The Allen-Bradley CSP/PCCC protocol supports communication with the Allen-Bradley devices of the SLC-500 series using a TCP connection.
It also supports communication via the DF1 gateway with SLCs that communicate via DH+ or DH485.
Communication was tested e.g. with the following SLC:
- SLC 5/05 1747-L551/C Ethernet Processor
- SLC 5/05 1747-L552/C Ethernet Processor
- SLC 5/05 1747-L553/C Ethernet Processor
Note: PCCC message encapsulation is also supported within the Ethernet/IP Protocol (communication with MicroLogix 1100 or SLC 5/05 1747-L553/C Ethernet Processor)
