I need to Migrate 10 micro logics 1100/1400s. They are all in the same room but in different cabinets. Changing any wiring would be expensive and not an option. They all have small projects and have between 0 and 30 I/O each. The processes are critical and can not shut down or be unreliable in any way.
Option one:
Micro 800s and CCW. I realize this is the straight forward answer but my customer hates CCW and may refuse this.
Option two:
Install one nice modern controller to replace all of them and use remote I/O.
This is my first instinct but I am worried about these critical processes now depending on Ethernet networking to function, I doubt the customer wants to pay for network upgrades.
Option three:
Multiple compact logics i.e. L306s
To me this is nice, but overkill and expensive.
Any better option?
Open to opinions
