Which PLC5 and SLC5 versions are compatible with ProSoft Ethernet/IP solutions?

PLC-5® and SLC™ 500 processors communicate using the Programmable Controller Communications Commands (PCCC) protocol.

Ethernet TCP/IP connectivity was originally added to the SLC 5/05 and PLC-5E using the proprietary Client Server Protocol (CSP), with embedded PCCC commands, CSP/PCCC.

The ControlLogix® and CompactLogix™ systems were developed with a new communications architecture based on the Control and Information Protocol (CIP).

In parallel, EtherNet/IP (EIP) has been developed to encapsulate CIP and PCCC.

ControlLogix and CompactLogix processors support EIP explicit messages, EIP/CIP, and EIP/PCCC.

The "Map PLC/SLC Messages" programming software feature allows the user to convert CIP to PCCC and vice versa.

CSP/PCCC is not compatible with EIP/PCCC or EIP/CIP.

PLC-5E and SLC 5/05 added support for EIP with embedded PCCC commands, EIP/PCCC.


The first PLC-5E revisions to support EIP/PCCC were:

 - Series C, Revision N.1

 - Series D, Revision E.1

 - Series E, Revision D.1


The first SLC 5/05 revisions to support EIP/PCCC were:

 - Series A firmware revision OS501, FRN5

 - All Series B and C.


ProSoft’s DFNT driver used in our 52xx-DFNT-xxxx gateways, support EIP/PCCC as Client, and EIP/PCCC and EIP/CIP as Server.

ProSoft’s EIP driver used in our PLX gateways and the AN-X2 driver used in our modernizations gateways, support EIP/PCCC and EIP/CIP as Client/Server. This driver supports also implicit I/O EIP as adapter (Server).
