Communication Between Unitronics PLC V560 and rectifier

[santosh]

Hello,

I am trying to communicate V560 with Rectifier through modbus RS485. 

PLC pin Details:-

Rectifier Pin details:- pcr01 protocol communication Ver 3_23 EN.pdf

protocol Support:-Mod bus ASCII

 

                                                                                                  fig 1.0

Please Reply Following Points:

1. Is it possible to communicate Unitronics PLC with Rectifier.

2. If Possible  how to connect between PLC and Rectifier.(PLC RS485 2 wire and Rectifier rs 485 4 wire ).

3. If I short TX+ to RX+ and TX- , RX- and connect A+ and A- terminal to PLC.

    is it okay this way?

4. Shall i need to use converter half duplex to full duplex .

5. Rectifier is Supports only MODBUS ASCII.

    Is it possible to connect as shown in  fig 1.0

Please reply with all possible solution.

Santosh,

It is possible to communicate as per shown in below set up.

You can connect multiple devices as per above set up with terminating last device with 120 ohm resister.

do it in this way and let me know.
