CI590-cs31 communication with plc PM592-ETH
CS31 bus is serial bus system, so be careful about not loop it.
Starting from master(plc) you have to jump from one node to other till last one.
At last point to terminate bus by using CI590 pins with cable(which is shown at its manual)
I also add a pdf which shows how to add CS31 bus to your plc system
Lastly be careful about adressing CI590 by its rotary switches.
Hi. There is limitation up to 31 stations (with up to 120 DIs/120 DOs or up to 32 AIs/ 32AOs per station) for solution based on CI590-CS31-HA (direct CS31 link connection to CPU).
If you are looking for more flexible solitution regarding I/O segmentation, there is ationally possible to design new schema/solution via CM574-RS + specific libraries (see attached document). Hope this help.
