Hello All,
I am new to the forum.
I am part of a group upgrading PLC5 equipment to Control Logix. We have just started the upgrades and are looking for some different options.
One of the options we are looking at is taking a group of 3 PLC5/40 processors, that are currently in 16 slot racks that are full, just digital I/O, no analogue, and using a single 1756-L72 processor to control the racks. We would pull the 5/40 processors and install ASB's in the short term, and use 1756-RIO cards in the Control Logix rack.
My concern is that that the process is extremely time critical. I worry that the RIO network would not be fast enough to control the I/O in the racks compared to having its own processor doing this. Much of the I/O is hardwired to other pieces of equipment to achieve interlocking.
Does any one have ay experience with this? Any idea how to calculate RIO network times for a situation like this?
Thanks in advance for any "input"
