Modbus Communication on AC900F controller
I trying to connect three Devices from different areas in the Plant to my AC900F Controller Modbus Channel. There are 2 Scales from Area1 and Area 2 Respectively, and a Modicon Controller from Area 3.
Unfortunately my channel 1 is been used for other critical scales.
I want to use Channel 2 on the AC900F Controller for this. I cannot daisy chain them as they are from different areas. Can I do this configuration below, Three Cables from different plant areas direct to the Channel 2 TX/Rx.
Suggestion will be welcome.
Attached is an image of network.
But the third device on a separate bus is not possible. Where would you terminate the 3rd device? You can't do it on the controller, because that would mess up the Termination of the line with the controller in the middle.
Maybe a Modbus multiplexer that connects to the 3 devices and has a single line connection to the controller could help you?
