α _2 Simple Application Controllers_ 

## **1. Communication Capabilities** 

The α2 Simple Application Controller has a wide range of communication capabilities that include remote programming, sending SMS messages to mobile telephones or e-mail accounts, and reading/writing data using a dedicated protocol. These powerful features bring a new era of information transfer possibilities to the simple application controllers. 

The α2 can be used to monitor and control machines in remote stations and notify maintenance personnel in case of machine error or emergency situations. Remote monitoring through the AL-PCS/WIN-E software (version 2.00 onwards), hereafter referred to as VLS, can provide machine production and status updates as well as enable programming or parameter updates without the necessity of local access. 

The Dedicated Protocol option gives the user the ability to transfer and monitor data from a peripheral device without the use of VLS software. Programmers familiar with C, C++, Visual Basic, or similar packages can write specialized communication programs. 

Both standard and GSM modems can connect to the α2 controller. 

The most powerful function is the ability to send SMS packets to e-mail accounts or mobile phones. 

The new functional block which strengthens the communication from external equipment was added to  α2 Controller (version 2.20 or later). 

The new functional blocks is "Short Message Receiving(SMR) "and" Call Detect (CD)." "Short Message Receiving (SMR)" changes an output by the character string of a mail account. And "Call Detect (CD)" By GSM modem or an analog modem that supports"Calling Line Identification Presentation(CLIP)", an output is changed by call RING of a telephone. This functionality enables messages to be sent from remote locations to maintenance personnel or the appropriate staff thus reducing downtime for machines and the necessity for on site personnel at each location. The α2 Series Controller can connect to a GSM modem or standard modem to provide remote program upload/download, to monitor devices, set Function Block parameters, or change the I/O status. Program upload/download can be performed remotely by a PC that is using VLS software. 

The procedure for Dedicated Protocol, which can remotely monitor or set parameters without using the VLS software, is discussed in Chapters 5 - 9. 

Error messages can be prepared and placed on the α2 display to be sent as the SMS packet. Please refer to section 2.3 to view the available character set for SMS/GSM communication. The α2 Series Controllers communicates with a GSM or Standard modem from the connection port on the right side. 

**==> picture [37 x 38] intentionally omitted <==**

Note: The α controller communicates to a modem via the left side port and cannot connect to a GSM modem.

## **2. SMS/SMR/CD Functions and the Modem Setting** 

SMS messages can be sent to mobile phones and e-mail accounts via a GSM modem if certain parameters in the α2 controller are correctly configured. 

The output of SMR changes, when the command text is exactly included in Short Message. The output of CD changes, when called from the modem that supports Calling Line Identification Presentation (CLIP). 

These parameters can be set quickly and easily in the VLS software or from the front panel keys. 

Refer to section 1.1 for the system configuration. 

## **2.1 Set the parameters of the GSM modem from VLS software.** 

The Visual Logic Software (VLS) provides the easiest method to set the parameters and download them to the controller. The communication method is the first setting necessary in the VLS software. 

When use a standard modem by CD Funcion Block, see section 3.3. 

Open or start a new program and then choose “Option” on the menu bar. Click “GSM and Serial Communication” to open the dialog box necessary to begin parameterisation.

- Note: *1 If a number of SMS Function Blocks have been used in one program the user must take care when calculating the message sending order. The first message to be sent depends on the first input signal turning ON. Thus, if other messages are waiting to be sent they are then placed in a waiting queue. However, since the waiting queue is scan dependant, if after one scan the controller has failed to send the first message due to a busy line, thus, the following message order is no longer dependant on input signals turning ON but is solely dependant on the Function Block order.

## **Application Example: Open roller shutter by phone call** 

A roller shutter gates the entrance to a company field. Normally pedestrians only can pass this gate. Four employees need to pass the gate with a company car. These employees can open the gate by simply calling a phone number with their cell-phone. 

Opening the gate by phone call is enabled only during normal workdays and business times (Time Switch). Outside the business times the company owner can enable the function for a fixed time to give an employee the chance to open the gate.

The 8-bit binary computer link string is sent from peripheral equipment to the α2 Series Controller using a combination of a AL2-GSM-CAB and user-made cross-cable. The Transmit message consists of either Format A or Format B. Refer to section 5.3 for further outline information. The reply generated from the α2 Series Controller informs the user of the status of the communication line, erroneous messages, status of function block bit data, status of function block word data and the status of the Time Switch settings. 

Accessible devices include: System Bits, Input/Output Terminals, Key Inputs, Link Inputs/ Outputs, Analog Inputs and Control (N) bits. Additional parameters must be entered for information exchange with Function Block data (Bit or Word) to be enabled.

## **5.2 Configuration Diagram** 

The Peripheral equipment acts as the Master in all configurations, hence, messages are never initiated from the α2 Series Controller. This configuration involves a personal computer acting as the Master and the α2 Series Controller the slave unit. 

Currently the α2 Series Controller contains an RS-232C interface, thus, only 1:1 communication is available.

## **5.3 How to read Dedicated Protocol** 

Format A for computer link is used for checking the communication line between the computer and the α2 Series Controller. Thus, the read/write format for the structure of the string is identical. Refer to section 7.1 for detailed 8-bit binary string structure. 

Format A: Communication Line Check

Format B for computer link is generally used for reading/writing to all internal devices, reading/ writing to function block bit/word data, run/stop mode and configuring the Time Switch settings. Thus, the command string is more complex compared to the Format A equilvalent.Refer to section 8.3 for detailed 8-bit binary string structure.

## **6.3 Settings for Dedicated Protocol - Front Panel Keys** 

The α2 Controller must be set up to use the Dedicated Protocol. The settings can be performed from the front panel keys or downloaded from the VLS software. The VLS settings are the simplest and most convenient method to enter the required settings but they can also take place from the front panel. 

After the settings are changed in the controller, the power MUST be cycled for the Dedicated Protocol settings to take effect.

_**The Command String 7**_ 

α _2 Simple Application Controllers_ 

## **7. The Command String** 

The following chapter explains the structure of both types of dedicated protocol format for the α2 Series Controller. The 8-bit binary protocol is available in two different formats: 

- 1 ) Format A 

- 2 ) Format B 

The Dedicated Protocol is based on a PC or Peripheral device sending messages to the α2 controller and in return receiving replies to those commands. The string of data that accomplishes these tasks is called the Command String. The Command String can be used to check the communication line, read/write from/to internal bit/word data, perform remote Run/ Stop operation with the controller, and to edit Time Switch data. The data contained in the Command String varies with the type of action to be accomplished. 

Two formats have been designed to carry the data - Format “A” for simple Communication line checks and Format “B” for the more involved data processing instructions. The information to construct and read Command Strings is explained in this   chapter. 

Communication between the computer and the α2 Series Controller is handled using interrupts. The Transmit/Receive process is completed after the last operation has been completed in the Function block sequence order. Refer to the Communication Timing section for further information concerning response delay time. 

**==> picture [37 x 38] intentionally omitted <==**

## Notes: 

## _Communication requirements_ 

- a ) Power to the α2 Series Controller 

- b ) Switching the Serial Com mode to Dedicated Protocol. Using the front panel keys select “Serial Com” from the “others...” menu. Select “Other Com” then proceed to cycle the power to accept the setting. Or, using AL-PCS/WIN-E please refer to Chapter 6. 

## _Communication Settings_ 

- a ) Baud Rate:                    9600bps 

- b ) Datalength:                    8bits 

- c ) Parity:                            None 

- d ) Stop bit:                         1 

- e ) Synchronous method:   Half-Duplex 

- f ) Framing, Overrun or communication errors will occur if the default communication dedicated protocol setting have not been entered. Using the front panel keys, select “Serial Com” from the “others...” menu. Select “Other Com” and adjust the “ComFormat, Station No. and Link Block” accordingly. Refer to Chapter 6 for detailed information concerning Front panel screen. However, the user can also set the default communication dedicated protocol settings from the VLS software.

Note: 

- 1 ) Format B WRITE/(RUN/STOP) operation can produce an error code even though a standard complete flag has been sent. If the Transmit message contains the correct syntax then a complete flag will be sent, however, if the reply data is corrupt then a NAK message will be generated. 

- 2 ) The write message string is intended for BIT data accessing, therefore, only one byte has been allocated to the Device Status setting. To write to WORD data, 2 bytes must be allocated to the Device setting. Thus, caution in setting the No. of communication bytes and the sum code check must be taken. 

Read/Write operation for Format B follows a different structure to Format A. Format B uses a more complex string to access internal devices. However, the write operation contains the Device Status parameter used to indicate the ON/OFF state of the intended device. 

Time Switch settings follow Format B protocol, however, the structure and content of the string differs from the standard READ/WRITE mode operation. Refer to section 7.6.5 for further detailed information concerning Time Switch settings for Format B.

## Note: Format B cautions 

## 1 ) READ Message - BIT data 

The maximum number of BIT devices that can be read at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB) and Device No. (HB). _**(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB)) = (250 - 4) / 3 = 246 / 3 = 82**_ 

Therefore, the user can read 1 - 82 BIT devices at any one time. 

## 2 ) READ Message - WORD data 

The maximum number of WORD devices that can be read at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB) and Device No. (HB). _**(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB)) = (250 - 4) / 3 = 246 / 3 = 82**_ 

Therefore, the user can read 1 - 82 WORD devices at any one time.

α _2 Simple Application Controllers_ 

## 3 ) WRITE Message - BIT data 

The maximum number of BIT devices that can be written at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB), Device No. (HB) and Device Status (1byte). 

_**(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB) + Device Status) =**_ 

_**(250 - 4) / 4 = 246 / 4 = 61**_ 

Therefore, the user can write 1 - 61 BIT devices at any one time. 

## 4 ) WRITE Message - WORD data 

- The maximum number of WORD devices that can be written at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB), Device No. (HB), Device Status (LB) (1byte) and Device Status (HB) (1byte). 

_**(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB) + Device Status(LB) + Device Status(HB)) =**_ 

_**(250 - 4) / 5 = 246 / 5 = 49**_ 

Therefore, the user can write 1 - 49 WORD devices at any one time. 

- 5 ) Time Switch READ Message. 

The READ operation of a Time Switch settings follows the identical structure to reading a Communication Word device in Format B. The maximum number of Time Switch devices that can be read at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in the reply message. 

_**(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (RTC0 + RTC1 + RTC2 + RTC3) =**_ 

_**(250 - 4) / 4 = 246 / 4 = 61**_ 

Therefore, the user can read 1 - 61 Time Switch settings at any one time. 

Refer to section 7.6.5 for further infromation concerning Time Switch settings. 

- 6 ) Time Switch WRITE Message 

The maximum number of Time Switch devices that can be read at any one time is restricted by the maximum number of communication bytes (250 bytes) contained in a single message. Each device is represented by the Device code, Device No, (LB), Device No. (HB), RTC+0, RtTC+1, RTC+2 and RTC+3. 

_**(Max No. of Comm. bytes - (Format No. + Stat No. + Command + No. of Devices)) / (Device code + Device No(LB) + Device No. (HB) + RTC0 + RTC1 + RTC2 + RTC3) = (250 - 4) / 7 = 246 / 7 = 35**_ 

Therefore, the user can write 1 - 35 Time Switch settings devices at any one time. Refer to section 7.6.5 for further infromation concerning Time Switch settings.

Locations for the System Bits, Inputs, Outputs, Keys, Link Input, and Link Output are permanent but the Function Block settings (Communication Bit and Word Devices) must be set in the “Options/Dedicated Communication” dialog box in the VLS software. Remember to set aside some memory in the same dialog box for these devices. Refer to section 6.1 for VLS settings.

## **7.3.8 Device Number** 

The Device Number is used in conjunction with the Device Code. Once the Device has specified what the internal device represents, then the Device Number is used to select the appropriate device from the range mentioned above. Each Device Number is comprised of 2 bytes: 

Lower byte (LB) 

Higher byte (HB) 

Example - The user wants to check the status of Input 11. Converting input 11 to a four digit Hexadecimal number 00 0B. The Higher Byte (HB) = 00. The Lower Byte (LB) = 0B. Thus, the user will enter the Device Code followed by 0B 00 to read/write data from/to Input 11. 

## **7.3.9 Device Status** 

- 1 ) BIT Device - A single byte is allocated to the Device Status when used for both READ and WRITE operations. 

## _**Table 7.9: Byte representation of the BIT status**_ 

|**State**|**Device Status (Hex)**|
|---|---|
|ON|01|
|OFF|00|



- 2 ) WORD Device - Two bytes are allocated to the Device Status when used for both READ and WRITE operations. Therefore, both the lowerbyte (LB) and Higherbyte (HB) of the device status when used in conjunction with a WORD application can allow the user to enter a maximum value of: 32767 (decimal) and minimum value of -32768 (decimal). The counter function block has a minimum value of 0 and the PWM function block has a minimum value of Period Time.

## **7.3.10 Sum Check** 

The Sum Check is the four digit Hexadecimal total of the numbers between the Format No. and the ETX command. The Sum Check numbers are Hexadecimal numbers with the Lower byte written directly after the ETX command and the Higher byte as the last two digits in the Command String.   The Sum check is used to verify the validity of the message. Format B - READ message

## 3 ) Command Example - **Weekly Time Settings** 

- The data in the Command code for a Weekly Time Setting consists of 4 bytes of data. To determine the hexadecimal numbers to put in the Command string, the entry data has been set up per the Table below. The Hexadecimal numbers can be determined after filling in the box with the appropriate data. 

_**Table 7.15:  Weekly Time Setting Schedule**_ 

|**Level**|**b7**|**b6**|**b5**|**b4**|**b3**|**b2**|**b1**|**b0**|
|---|---|---|---|---|---|---|---|---|
|RTC+0|“1”|“0”|“0”|“0”|“0”|“0”|“0”|“0”|
|RTC+1|Week 5|Week 4|Week 3|Week 2|Week 1|Saturday|Friday|Thursday|
|RTC+2|Wednesday|Tuesday|Monday|Sunday|Hour|Hour|Hour|Hour|
|RTC+3|Hour|Min|Min|Min|Min|Min|Min|On/Off|



**==> picture [38 x 36] intentionally omitted <==**

## Notes: 

The Values in quotation marks “x” are defined for the weekly setting and will not change. The Values for the Hour parameter is a 5 digit binary number with a range of 0 to 23. The Values for the Minute parameter is a 6 digit binary number with a range of 0 to 59. 

a ) Example - Send Data to Time Switch Setting 1 so that Monday, Wednesday, and Friday of the First Week of Every month at 10:00 AM the Output turns On. 

## Step 1 

The values in +0 level are fixed as described above. 

|**Level**|**b7**|**b6**|**b5**|**b4**|**b3**|**b2**|**b1**|**b0**|
|---|---|---|---|---|---|---|---|---|
|RTC+0|“1”|“0”|“0”|“0”|“0”|“0”|“0”|“0”|



Step 2 

The **Weekly** values are shown below where only Wk 1 is activated. 

|**Level**|**b7**|**b6**|**b5**|**b4**|**b3**|**b2**|**b1**|**b0**|
|---|---|---|---|---|---|---|---|---|
|RTC+0|“1”|“0”|“0”|“0”|“0”|“0”|“0”|“0”|
|RTC+1|Wk 5 = 0|Wk 4 = 0|Wk 3 = 0|Wk 2 = 0|Wk 1 = 1|Saturday|Friday|Thursday|
|RTC+2|Wednesday|Tuesday|Monday|Sunday|Hour|Hour|Hour|Hour|
|RTC+3|Hour|Min|Min|Min|Min|Min|Min|On/Off|



Step3 

The **Daily** Values have Monday, Wednesday and Friday = 1. 

|**Level**|**b7**|**b6**|**b5**|**b4**|**b3**|**b2**|**b1**|**b0**|
|---|---|---|---|---|---|---|---|---|
|RTC+0|“1”|“0”|“0”|“0”|“0”|“0”|“0”|“0”|
|RTC+1|Wk 5 = 0|Wk 4 = 0|Wk 3 = 0|Wk 2 = 0|Wk 1 = 1|Sat = 0|Fri = 1|Thur = 0|
|RTC+2|Wed = 1|Tues = 0|Mon = 1|Sun = 0|Hour|Hour|Hour|Hour|
|RTC+3|Hour|Min|Min|Min|Min|Min|Min|On/Off|

_**The Command String 7**_ 

α _2 Simple Application Controllers_ 

## Step 4 

The **Hourly** value is a five digit binary value for 10. 10 (dec) = 01010 binary. 

|**Level**|**b7**|**b6**|**b5**|**b4**|**b3**|**b2**|**b1**|**b0**|
|---|---|---|---|---|---|---|---|---|
|RTC+0|“1”|“0”|“0”|“0”|“0”|“0”|“0”|“0”|
|RTC+1|Wk 5 = 0|Wk 4 = 0|Wk 3 = 0|Wk 2 = 0|Wk 1 = 1|Sat = 0|Fri = 1|Thur = 0|
|RTC+2|Wed = 1|Tues = 0|Mon = 1|Sun = 0|Hour = 0|Hour = 1|Hour = 0|Hour = 1|
|RTC+3|Hour = 0|Min|Min|Min|Min|Min|Min|On/Off|



## Step 5 

The **Minute** value is a 6 digit value for 0. 0 (dec) = 000000 binary. 

|**Level**|**b7**|**b6**|**b5**|**b4**|**b3**|**b2**|**b1**|**b0**|
|---|---|---|---|---|---|---|---|---|
|RTC+0|“1”|“0”|“0”|“0”|“0”|“0”|“0”|“0”|
|RTC+1|Wk 5 = 0|Wk 4 = 0|Wk 3 = 0|Wk 2 = 0|Wk 1 = 1|Sat = 0|Fri = 1|Thur = 0|
|RTC+2|Wed = 1|Tues = 0|Mon = 1|Sun = 0|Hour = 0|Hour = 1|Hour = 0|Hour = 1|
|RTC+3|Hour = 0|Min = 0|Min = 0|Min = 0|Min = 0|Min = 0|Min = 0|On/Off|



## Step 6 

Finally, the On/Off value is 1 for On and the table is complete. 

|**Level**|**b7**|**b6**|**b5**|**b4**|**b3**|**b2**|**b1**|**b0**|
|---|---|---|---|---|---|---|---|---|
|RTC+0|“1”|“0”|“0”|“0”|“0”|“0”|“0”|“0”|
|RTC+1|Wk 5 = 0|Wk 4 = 0|Wk 3 = 0|Wk 2 = 0|Wk 1 = 1|Sat = 0|Fri = 1|Thur = 0|
|RTC+2|Wed = 1|Tues = 0|Mon = 1|Sun = 0|Hour = 0|Hour = 1|Hour = 0|Hour = 1|
|RTC+3|Hour = 0|Hour = 0|Min = 0|Min = 0|Min = 0|Min = 0|Min = 0|On =1|



To values to put into the Command String must be in Hexadeximal values. Combine the table bits b4-b7 and b0-b3 to give a two digit Hexadecimal number. 

Step 7 

_**Table 7.16:  Weekly Setting Table with Hexadecimal Values**_ 

|**Level**|**b7**|**b6**|**b5**|**b4**|**b3**|**b2**|**b1**|**b0**|**Hexadecimal Command**<br>**String Value**|
|---|---|---|---|---|---|---|---|---|---|
