Looking to interface a MUX (16ch) to a Allen Bradley point IO. The main reason behind this is to make some savings from using the PLC AI cards.
Currently the process has a main PLC - compact logix L33ER with a number of digital I/Os.
Next to that is a point IO with a few digital I/Os and a large number of AI. All of which are temp transmitters.
There are 80 transmitters in total.
In short:
L33ER-------------DeviceNetPointIO-------MUX---MUX---...
I am hoping to use a 16 channel MUX from some vendor (possibly IFM?) that can use a Ethernet based protocol (possibly IO Link) to connect to the point IO.
Which can then be received at the main (compact logix PLC).
Can anyone please share your thoughts on achieving this design this way or a better way?
What are some of the considerations I need to take in place to get this in terms of configuration, network traffic etc?
Thanks in advance.
