Prosoft PLX82-MNET-61850 Modbus TCP/IP to IEC 61850 Gateway

The Modbus® TCP/IP to IEC 61850  gateway enables communication between

the Intelligent Electronic Devices (IEDs) on an IEC 61850 network and

Programmable Logic Controllers (PLCs) or Programmable Automation

Controllers (PACs) on a Modbus TCP/IP network.

The configuration utility software provided with the gateway uses IED

configuration files to import complex IEC 61850 data structures. The utility

creates Variable files and Function Block files for import into Unity Pro projects

for Quantum or M340 processors.

IEC 61850 is the international standard that defines the hardware and

communication requirements for all devices within substation automation. The

standardized naming conventions imposed by the IEC 61850 standard

improves interoperability between systems provided by diverse manufactures or

created by multiple system integrators.

Features

Configuration Utility Integrates

Tightly with Unity Pro

 Application-specific Variable and Function Block files are automatically generated.

 Users are not required to develop communication logic or tag structures in their PLC or PAC

projects.

Configuration Archive and

Diagnostics

 The gateway configuration file can be stored on an optional removable 1GB industrial SD

card. This allows for rapid disaster recovery by moving the SD card from a failed gateway to

a replacement gateway.

 Extensive diagnostics for the gateway and for both Modbus TCP/IP and IEC-61850 networks

are available via the configuration utility.

Import Configured IED files

 All IED data attributes are available for convenient mapping to Modbus registers.

Modbus TCP/IP Client/Server

support

 Enables multiple Modbus TCP/IP devices or SCADA devices to interface with IEC-61850

devices simultaneously.

Configuration

ProSoft 61850 Configuration Manager software, provided with the gateway, is used to develop and manage gateway

configuration files, as well as to view communication and network diagnostics.

 Import CID and SCD files

 Drag and drop IEC 61850 Data Attributes for Modbus mapping

 PLC or PAC Tag names are automatically created

 Print mapped tag list

 Tag file export (.CSV)

 Export .XSY (Variable) and .XFM (Function Block) files for use with Unity Pro

Specifications - Modbus TCP/IP

The Modbus TCP/IP driver allows multiple independent, concurrent Ethernet

connections. The connections may be Clients, servers, or a combination of both Clients

and servers.

Modbus TCP/IP Client

 Actively reads data from and writes data to Modbus TCP/IP devices using MBAP

messages on Service Port 502 or Encapsulated Modbus RTU messages on other

Service Ports.

 Supports up to 10 Client connections (max. 2000 commands) to multiple servers.

 Modbus Command optimization - Multiple tags can be combined into one Write

command with up to 120 words.

Modbus TCP/IP Server

 Accepts incoming connections on Service Port 502 from Clients using Modbus

TCP/IP MBAP messages and on Service Port 2000 (or other Service Ports) from

Clients using Encapsulated Modbus messages.

 Supports up to 20 independent, concurrent server connections for any combination

of Service Port 502 MBAP messages and Encapsulated Modbus RTU messages

on other Service Points.
