Data from an Allen Bradley PLC using DF1 or CSP protocols is requested using a "file" identifier and a register number within that file as the specified starting address. The file may contain a mix of different data types. The RediGate's Poll Table is able to read a block of registers from the PLC and parse them into Real-time Database (RTDB) registers using the appropriate data types.


DF1 protocol can be used on Rockwell/Allen-Bradley devices:

The RediGate's DF1 and CSP protocols over an Ethernet connection is also referred to as PCCC. This document does not describe configuration of Allen Bradley EtherNet/IP CIP protocol. The RediGate does not currently support Data Highway Plus (DH+), which requires a special hardware interface.
