User manual - DP400S - 15 

- **Sampling value** . This proceeding performs a calibration of the analog input on two points of the scale taking as reference two known values (for example for a load cell these values could be Zero balance and Reference weight). It is possible to link the calibration lower limit (parameter 6 Lower lim.) to the minimum value of the sensor or to the minimum position of the potentiometer while the calibration upper limit (parameter 7 Upper lim.) may be linked to the max value of the sensor or the maximum position of the potentiometer.

- **Full-scale % value** . This proceeding is available for 6wires (4wires+2 wires calibration) strain-gauge sensors and for Melt transducers. It is possible to calibrate reading of analog input by choosing the percentage of the full-scale value at which the calibration of the upper limit will be performed. At first the operator will be asked to select the percentage for the calibration of the upper limit. Afterward the lower limit value and upper limit value (% of full-scale value) will also be calibrated, as for the sampling value. The two calibration wires of the sensor can be connected to relay of output Q2 to perform a semi-automatic calibration. In this case it is necessary to select the option Calibration % on parameter Alarm 2 - Type of alarm. If contact Q2 will not be used to generate sensor calibration signal, it is possible to short-circuit externally the two wires, waiting for stabilization of reading on the device and then proceeding to calibration of upper limit.

## **7.8 Customizable linearisation of analog input** 

Selecting **16 steps** on parameter 17 **V/I custom** and connecting a linear sensor it is possible to customize the linear input for a max. of 16 steps. On parameters **xx-Input value** it is necessary to enter the value of the input to which the value selected on the corresponding parameter **xx-Custom value** will be related. EExample: sensor 0-5V. 

01-Input value=> 0.000V 02-Input value => 2.000V 03-Input value => 4.000V 04-Input value => 5.000V 

01-Custom value=>0mBar 02-Custom value=>100mBar 03-Custom value=>500mBar 04-Custom value.=>1000mBar 

At each value in Volt (input) a value in mBar (customized) is related: if the sensor supplies 2V the device visualizes 100mBar, if it supplies 4V the device visualizes 500mBar. For intermediate tension values the value in mBar is calculated linearly between the entered values containing it: 1V = 50mBar, 3V=300mBar and 4,5V=750mBar.

User manual - DP400S - 23 

## **9 Data logger** 

DP400S features a basic data logger function which can be enabled on parameter 109 **Data logger.** After the initial start-up following the switch-on, the device will start to save process data on EEPROM according to a selected time basis. Sampling time must be selected on parameter 110 **Datalogger time** . Stored data may be read via Modbus protocol starting from address 6001 (MSW) or 9001 (LSW) (see following section of this manual). The following table provides info about the stored data: 

6001(H) 6002 (L) Data logger: frmware version 6003(H) 6004 (L) Data logger: sensor type 6005(H) 6006 (L) Data logger: decimal point 6007(H) 6008 (L) Data logger: measure unit 6009(H) 6010 (L) Data logger: sampling time in seconds Data logger: flag end of memory. **0** indicates that memory is still available. **1** indicates memory is saturated 6011(H) 6012 (L) and device restarted to store data from address 6033/6034 6033(H) 6034(L) First analog input value stored. 6035(H) 6036(L) Second analog input value stored. ... ... ... 8031(H) 8032(L) Last analog input value stored. 

Reading of value 0x80000000 (-2147483648) stands for end of stored data: eventual data which should be read afterwards are not valid. 

## **10 Serial communication** 

DP400S is equipped with RS485, it can receive and broadcast data via serial communication using MODBUS-RTU protocol. The device is configured as a Slave. This function enables the control of multiple devices connected to a supervisory system. Each controller responds to a master query only if the query contains the same address as that in the parameter 126 **Slave address** . 

The permitted addresses range from 1 to 254 and there must not be controllers with the same address on the same line. 

24 - DP400S - User manual 

Address 255 can be used by the master to communicate with all the connected equipment (broadcast mode), while with 0 all the devices receive the command, but no response is expected. 

DP400S can introduce a delay (in milliseconds) in response to the master request. This delay must be set on parameter 129 **Serial Delay** . 

Each parameter change is saved by the controller on EEPROM memory (100000 writing cycles). 

**NB** : changes made to Words that are different from those reported in the following table can lead to malfunction.
