Hello! The screenshots show the code instructions, HW configurations and the slave Modbus communication module. The slave receives a message from the PLC, but does not transmit the registers, because the Rx message does not have a CRC. My hardware: Simatic S7-1200 CPU 1212C DC / DC / DC, ET 200 SP, CM PtP. A half-duplex RS-485 2-wire interface is used. Thank you! AttachmentMODB_DATA.zip (207 Downloads) |
