V350-T2 RS-485

[jesuscardenas]

HELLO, I have an oplc vision V350-35-T2, I want to make a modbus communication
 with two frequency inverters through the communication connector configured in RS-485.
 I want to know if in this configuration it is possible to load/download the oplc and enter online mode.

Hi;

The V350-35-T2   has 1 Com Port  and a USB port for programming.   -- They both share the Same port - Port 1.

        Programming, Online Monitoring  and RS485 Modbus through this port will be a challenge for troubleshooting and programming.

 

I will recommend using a 2nd   Com Port for the RS485 communications   -- V100-17-RS4X ( isolated RS485)

     Then you will be able to go online and monitor the communications with the drives thru the programming port - Com 1.

    The cost of the module  will pay for itself in reducing time and effort.
