Hello, I am currently using a T100MD2424 with an I-7017 module using the RS485 network. The PLC is the Master and the 7017 is the Slave.
I want to add a Maple Systems Touchscreen HMI, which I believe will act only as a Modbus Master. Can I still have the PLC interrogate the 7017 for analog data and still respond to commands from the Touchscreen? Or. do I have to reconfigure the system to have the Touchscreen interrogate the 7017 directly and then tell the plc to execute commands based on the data received from the 7017?
Primarily the HMI will be displaying readings of analog data recieved from the machine process, although I will be adjusting alarm setpoints on the display.
