Modbus TCP/IP to IEC 61850 Dual Port Gateway
PLX82-MNET-61850
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.

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 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

Specifications – SNTP/NTP Client
The gateway supports a Simple Network Time Protocol (SNTP/NTP) client service that can synchronize the gateway’s time by periodic update requests to a Coordinated Universal Time (UTC) system. The user can configure the SNTP/NTP server details in ProSoft 61850 Configuration Manager. The resolution of the time is in milliseconds (ms).
| Configurable Parameters | SNTP/NTP server synchronization rate (in minutes)
