Modbus TCP/IP to IEC 61850 Gateway
Modbus TCP/IP to IEC 61850 Gateway
The ProLinx 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
|
Benefits
|
|
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 is stored in an 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, 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
The gateway is enclosed in a sturdy extruded aluminum case with DIN-rail-mounting.

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 with a maximum of 2000 commands to talk to multiple servers
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
