Hello, I am developing an application where I am connecting RAPID SCADA to Devices using Modbus TCP. I can read and send commands to the first device in the added devices under Modbus TCP communication line. But when I am trying to send ON/1 command to the second device, message pops up as ‘The Command is rejected by the server’. But I can read and write continuous values for the same device. Please help to fix it. Thanks in advance.
