Modbus TCP and PCCC Register Map. For a detailed explanation of the register
contents, please see the description of the associated DataStick Command in the
DataStick Measurement System Instruction Manual, Catalog Number MAN011DS-4.
7.1.1 Modbus TCP Reference
Modbus-IDA,
7.2 Programmable Controller Communication Commands
(PCCC)
This section describes how to communicate with an Ethernet product using an Allen-
Bradley SLC 5/03, SLC 5/04 or SLC 5/05 PLC using Programmable Controller
Communication Commands (PCCC).
The Ethernet product (server) mimics the behavior of a PLC5 in order to enable
communications with a PLC5, SLC 5/03, SLC 5/04 or SLC 5/05 PLC (client). The
PCCC object in the Ethernet product is accessed remotely using explicit messaging via
EtherNet/IP. In order to read registers in the Ethernet product, the PLC must issue a
Peer-To-Peer Read command to the Ethernet product. In order to write registers in the
Ethernet product, the PLC must issue a Peer-To-Peer Write Command to the Ethernet
product.
The PCCC Register numbers are shown in the tables in Section 7.3,
