IEC60870-5-101 Master Communications Module

MVI71-101M

The MVI71 IEC 60870-5-101 Master Communication Module allows Rockwell Automation PLC processors to interface easily with IEC 60870-5-101 slave (controlled unit) devices.

Features and Benefits

The MVI71-101M module interfaces up to 32 serial communication devices with the Rockwell Automation PLC processor. Two communication ports on the module act as controlling devices (masters) to interface with controlled devices on their own networks. Each port is individually configurable and can be set for balanced or unbalanced mode. Data is exchanged between the serial network and the Rockwell Automation processor using the internal database contained in the module and direct control by the controller's ladder logic.

General Specifications

• Single Slot - 1771 backplane compatible
• The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
• Ladder Logic is used for data transfer between module and processor. Sample ladder file included.
• Configuration data obtained from configuration text file downloaded to module. Sample configuration file included.

The MVI71-101M module is the ideal solution for many applications where IEC protocol connectivity must be added to a PLC system. The IEC solution is designed to address the expanding interest in the IEC protocol and the use of IEC compatible devices in industrial applications such as those in the water/wastewater power and oil & gas industries.

Compatible devices include relays, breakers, sub-station Communication Modules and other serial communication devices.
