jesuscardenas Posted December 7, 2022 Report Share Posted December 7, 2022 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. Quote Link to comment Share on other sites More sharing options...
DanT Posted December 8, 2022 Report Share Posted December 8, 2022 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. DanT Quote Link to comment Share on other sites More sharing options...
