## Chapter 2 UDP Based Monitoring for the SX Series Safety Laser Scanner 

The SX Series Safety Laser Scanner supports a UDP client-server communication over Ethernet (up to 100 Mbps) that allows a PLC or computer (client) to run the SX Series Safety Laser Scanner monitoring function on the SX Series Safety Laser Scanner (server). 

**==> picture [256 x 239] intentionally omitted <==**

PLC or SX5 (alone<br>computer or cluster)<br>Start Monitoring<br>Monitoring Frame<br>Monitoring Frame<br>...<br>Stop Monitoring<br>**----- End of picture text -----**<br>


Activating the monitoring function makes it possible to receive measurement distance data and information about the status of the scanner. Information is sent to the PLC or computer by a continuous flow of UDP packets. 

If multiple scanners are connected to each other as a cluster, the main unit, Master unit, is responsible for collecting and sending all monitoring frames to the client (PLC or computer). 

The data sent from the master device to the client for each complete scan are structured in 6 monitoring frames (see "Monitoring Frame (from Device to Client)" on page 11 ). If remote devices are connected to the Master device, an additional monitoring frame is sent for each remote device. 

## Client Disconnection 

Because UDP is a connectionless protocol, disconnecting the client (PLC or computer) from the network (that is, unplugging the Ethernet cable or power off the client) does not result in stopping the monitoring function: If the client’s IP has not changed, reconnecting the client to the network allows the monitoring frames to reach the client again. If the client’s IP has changed (or the client has been replaced with another one), frames do not reach the client since they are still sent to the previous IP address and port.

UDP Based Monitoring for the SX Series Safety Laser Scanner 

## How to Create the Start and Stop Messages 

The start and stop messages, referenced in the next section, are created in the SX Series Safety Laser Scanner Configuration Software. 

In the Configuration Software version 3.1.3 or higher the option to Generate Advanced Monitoring Messages exist. Open the desired configuration that contains the topography of the cluster (Master model and appropriate number of remotes) or create the structure. Under the small Options menu is Advanced Monitoring . 

## Generate Advanced Monitoring Messages 

From this box the area from which the data is gathered can be limited by entering a start and stop angle. The angular resolution can be selected. The scanner’s safety function has a resolution of 0.1 degree, but this results in a lot of data. The resolution can be selected from 0.1 degree up to 5 degrees. For the remote scanners, the resolution can be selected from 0.5 degree up to 5 degrees (only 1 packet per remote). 

If any of the special data is desired, enable it in the Special Data box. First, enable the Special Data box from the Special Data menu in the Data box. 

To receive data from a remote scanner, select the desired remote page in the Generate Advanced Monitoring Messages page. Then enable the Monitoring .

SX5 Safety Laser Scanner Advanced Measurement Communication Manual 

Enter the IP address and port of the client (PLC or computer) in the Network box. 

After the desired settings have been selected, click Generate to create the START and STOP messages. Once generated the START and STOP messages can be copied. 

WARNING: Advanced Measurement data may only be used for general monitoring and control activities. Do not use this data for safety-related applications.

## Chapter 3 Command List 

The Advanced Measurement protocol includes the following messages: 

- Start Request 

- Start Reply 

- Monitoring Frame(s) 

- Stop Request 

- Stop Reply 

The "Appendix" on page 22 provides some examples of the available messages described in this chapter. 

## Start Requestion (from Client (PLC or computer) to Device) 

The start command must be sent to the SX Series Safety Laser Scanner IP address using UDP port 3000. This command provides the device with information to be sent back to the client. 

NOTE: Banner recommends that the Start command be generated using the SX Series Safety Laser Scanner Configuration Software ( Options › Advanced Monitoring ). This ensures that the message is correct and that the information requested meets the communication band. 

The UDP payload uses the following format.  Unless otherwise indicated, the byte order is little endian.

## Monitoring Frame (from Device to Client) 

Monitoring frames are sent by the SX Safety Laser Scanner after a start command. Monitoring frames are sent to the IP address and UDP port specified by the Start Command message. 

Each monitoring frame is always composed of: 

- 6 messages for the Master device 

- 1 message for each Remote device 

Each message is composed of the following elements: 

- The same information is always stored in the first 19 bytes. 

- The remaining bytes are variable in number and depend on the configuration sent with the Start Command. Each configuration sent with the Start Command prompts the system to send data in the monitoring frame. For more information on decoding additional information, refer to "Additional Information" on page 13 

- The end of the message is given by either the length or the end message header ID with LEN 0.

Command List 

SX5 Safety Laser Scanner Advanced Measurement Communication Manual 

The formula to compute the angular region interested by the measures of a frame is: 

Start angle = “FromTheta” /10 {degrees} 

End angle = (“FromTheta” + (“Resolution” × “Number of Samples”)) / 10 {degrees} 

For example: A frame with “From Theta” equal to 0, “Resolution” equal to 1 and “Number of Samples” equal to 500 covers the angular region from 0 to 50°.

## I/O Pin State 

The input state area is split into two sections: physical inputs and logical inputs. 

Because inputs may change at a frequency higher than the message transmission, the physical input section consists of three identical records that store the last three sets of input values. Each record is described in the following table:

## Data Processing Time 

The time to process data from UDP command communications is as follows.

The communication time between the SX5 and other devices (that is, PLC or computer) differs depending on your communication environment. 

The time elapsed from the acquisition by the SX5 of the first measure contained in a frame and the expedition of the corresponding UDP frame depends on the actual scanner and on the number of connected SX5 devices. Refer to the following table.

## Monitoring frame created by the Master Scanner 

The Master scanner divides its 275° into six zones: five zones of 50° each and the last zone of 25°. Each zone corresponds to a different frame (the Master scanner needs a total of six frames to transfer a complete set of measures). 

The following figure shows the Master frame for the first zone (0° – 50°).

## Monitoring frame from Remote Scanner 

Differing from the Master, a Remote scanner does not divide its 275° into six zones, but it can send all 275° of values through a single frame. The maximum resolution it can support is 0.5 degrees, which is why a single frame for each scan is enough to send all the data. 

The following figure shows the frame of a Remote Scanner:

In this case, the Master frame is received as in "Master Frame Content on page 30: the first and last frames are outside the angel range requested and all header IDs are present except for the payload of measure related data (measure, intensity and point in safety), for which the header ID length is equal to one. 

The second and fifth frames contain measure related data of only a part of the sector.
