Hi experts, A. Used Hardware: 1. PLC s7_1214C DC/DC/DC_Version 4.1 2. CM 1241 (RS442/485) version 2.1 B. Used Software: 1. TIA PORTAL V13_SP1(Step 7 + PLCsim) 2. MODBUS_MASTER_RTU intruction version 2.2 3. MODBUS_COMM_LOAD_RTU intruction version 3.0 C. The following content: When I simulate the program on PLCSIM: No problem with MODBUS_COMM_LOAD However, when MODBUS_MASTER is clicked a positive edge, the BUSY leg moves from 0 to 1, it stays in state 1 without returning to state 0. As a result, the MASTER_DONE does not move to 1 to indicate the sending process. The request to SLAVE is complete. No errors occurred during program execution. Please help! Thanks!
