Delta DVP- ES2 Series PLC

This guide will show you how to connect the Polar Gateway to Lovato Delta DVP-ES2 PLC. It will also take you through how to set up the parameters required Delta DVP-ES2 series drives to ensure communications to the Gateway.

Steps to follow:

  1. Connect power to the Gateway.
  2. Connect RS-485.
  3. Final checks.
  4. Power on the system.
  5. Configure the Delta DVP-ES2 Serial Parameters

1. Connect power to the Gateway.
Power Polar Gateway

Wire the Polar Gateway to a 12-24 V DC power supply. Connect the positive wire to the positive terminal and the negative wire to the negative terminal.

2. Connect RS-485.
Polar Gateway RS-485
DeltaDVP ES Series RS-485

Wire the RS-485 cable to allow communication with the Polar Gateway device. Connect A+ => D+ and B => D-.

3. Final checks
Before you switch on the device make sure you have done everything correctly in the previous steps.
 
  • Make sure the power is OFF while doing the cable wiring.
  • Re-check if there are no short circuits.
  • Check if the power cables are not loosely wired to the Gateway.
  • Check if the power cables are not loosely wired to the Programmable Logic Controller.
  • Re-check the RS-485 twisted pair cables is correctly connected A+ => D+  and B- => D-.
4. Power on the system

Now you are ready to go, you can now switch on the Polar Gateway and the Delta DVP-ES2.  

5. Configure Delta DVP-ES2 Serial Parameters
In order for the Gateway to correctly communicate with the Delta DVP-ES2  controller, there will need to be some changes made to the communication parameters. 

Note: It is critical to change the default settings to reflect the table below, these changes are made using a ISPSoft Software for PLC programming, you would need to understand PLC programming to do this or get a specialist to do that for you.

Serial Communication Setup

Edit the DFB_COM2_Protocol [DFB] function block parameters to match that of the table below.

 

Name Description Parameter Required
Station IDSlave ID/Node IDStat_Add1
ParityParityParity1 = None
Stop bitsStop bitsStop_B1
Baud RateCommunication SpeedBaud_R1 = 9600
Data lengthData lengthData_Len2 = 8 bits
Protocol Communication protocol A_R2 = Modbus RTU

You may now sign in to the Polar Portal to monitor the device remotely, the button on the right will take you through a setup process.
