Problems with setting Modbus Master CP341

PLC_inside Posts: 9 Rating: (0)	Can anyone helps with such problem. I have CPU313C with CP341, and I can't receive data from other Modbus RTU slave. Protocol sets similar, I can see that we have request for slave by blinking TXD on CP341. But I not receive any data. I think that I have errors possible in not correct request. My project is in attachment. I try to use 03 func modbus, and read 30h function data. My best regards. Attachment master.ask.slave.zip (57 Downloads)
