2.1 General
Overview
Automating integration for Schneider Electric (SE) Modicon processors and
maximizing ease-of-use are the hallmark design criteria behind the new ProLinx
SE line of communication gateways. The first SE gateway, the 5204SE-MNET-
PDPMV1 Modbus TCP/IP to PROFIBUS DP-V1 Master gateway, easily turns a
Modicon M340 or Quantum Programmable Automation Controller (PAC) into a
PROFIBUS DP-V1 Master. The new Application Communication Logic functions
built into ProSoft Configuration Builder (PCB) automatically generate all the Unity
Pro data types, variables, and logic required for the processor to perform
PROFIBUS DP-V1 cyclic and acyclic communication.
PCB automatically generates customized export files based on the gateway's
PROFIBUS DP network configuration. You can import these files into Unity Pro
version 4 software without modification, eliminating the need to write additional
communication message logic.
Automatically-generated Derived Function Block logic also provides advanced
PROFIBUS DP-V1 acyclic message pass-through capability. Acyclic messaging
allows the processor to request extended slave data and diagnostics, as well as
access slave-specific special functions.
If you change the configuration of your PROFIBUS DP network in ProSoft
Configuration Builder, you can easily export new logic files, and then import them
into an existing project.
