PROFIBUS Master for Modicon Modbus TCP/IP


Discontinued: No new product for sale. More Info
Recommended replacements: PLX51-PBM

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 a 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 M340 or Quantum to perform PROFIBUS DP-V1 cyclic and acyclic communication.

PCB automatically generates customized export files based on the PROFIBUS DP network configuration for the gateway. These files import into Unity Pro version 4 software without modification, eliminating the need to write additional communications message logic.

Automatically-generated Derived Function Block logic also provides advanced PROFIBUS DP-V1 acyclic message pass-through capability. Acyclic messaging allows an M340 or Quantum to request extended slave data and diagnostics, as well as access slave-specific special functions.

Whenever the PROFIBUS DP network configuration changes, new logic files can be automatically created, exported, and imported into an existing project, reducing engineering demands and cutting deployment time. Changes to gateway configuration can be password-protected.

The Modbus TCP/IP (MNET) driver can be used to interface many different protocols into the Schneider Electric Quantum family of processors as well other software solutions supporting the protocol. The MNET driver supports Client connections as well as Server connections.

The PROFIBUS DP Master protocol driver (PDPMV1) supports complete Master specifications according to IEC 61158 on either a Mono-Master or Multi-Master network. The module supports the DPV1 specification.
