PNOZ mc8p Ethernet IP / Modbus TCP
Introduction
This chapter describes the special features of communication with the PNOZ mc8p expan-
sion module on Ethernet IP and Modbus TCP. Acess to PNOZmulti data via tables and
segments is described in Chapters
Basics [ 13] and PNOZ mc2p, PNOZ mc2.1p, PNOZ
mmc11p (SDO and PDO) [ 21] .
Overview
The expansion module PNOZ mc8p connects the configurable control system PNOZmulti
via Ethernet to control systems that support the Ethernet IP and Modbus TCP protocols.
Ethernet IP and Modbus TCP are designed for fast data exchange at field level. The expan-
sion module PNOZ mc8p is a passive Ethernet IP (adapter) or Modbus TCP (slave) sub-
scriber. The basic functions of communication with Ethernet IP or Modbus TCP conform to
IEEE 802.3. The central controller (master) reads input information from the slaves and
writes output information to the slaves as part of each cycle. As well as the cyclical transfer
of usable data, the PNOZ mc8p can also be used for diagnostics and commissioning func-
tions.
