Most SLC 500 systems move to CompactLogix in phases. The processor is replaced first, inside one planned shutdown, and the new controller runs the SLC I/O you have. The I/O follows later, one rack at a time.

SLC 500 processors and I/O, and the networks around them: DH-485, Data Highway Plus, DeviceNet and Ethernet. Most plants move to CompactLogix, on Rockwell's standard migration path. If you would rather move to another platform, we will work to that.
The engineers who upgrade your system will plan the work around your shutdowns. Behind them are the controls engineers, electricians and panel shop that rebuild and upgrade plants and vessels across the Pacific Northwest. If the job needs another trade, we will send them.
