IEC60870-5-101 Slave Communications Module

MVI71-101S

The MVI71 IEC 60870-5-101 Slave Communication Module allows Rockwell Automation PLC I/O compatible processors to interface easily with IEC 60870-5-101 protocol compatible hosts. The module's two powerful and highly configurable ports allow the many SCADA host systems supporting the IEC protocol to be integrated into the PLC platform.

Features and Benefits

The MVI71-101S module is the fastest and easiest way to add IEC 60870-5-101 protocol interface support to the PLC platform. It is a single slot, backplane compatible solution for the Rockwell Automation PLC platform. This module has two powerful and highly configurable IEC 60870-5-101 Slave ports, allowing the many SCADA and field devices supporting the IEC protocol to be integrated into the PLC platform.

The MVI71-101S module acts as an input/output module between the IEC 60870-5-101 telecontrol network and the Rockwell Automation PLC backplane. The data transfer from the PLC processor is asynchronous from the actions on the network. A 5000-word register space in the module exchanges data between the processor and the telecontrol network.

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.

Applications

The MVI71-101S Slave module is designed to address the application where a host systems using the IEC 60870-5-101 protocol must communicate with a PLC processor. As such, the IEC Slave module can be used as a gateway in many SCADA installations in industries such as:

• Power and distribution applications
• Petrochemical
• Water and Gas Applications
• Oil and Gas production

Functional Specifications

The MVI71-101S module accepts commands from an attached master unit. A port configured as a virtual slave permits a remote master to interact with all data contained in the module. This data can be derived from the PLC processor. The remote master device uses the fully-configured databases in the module to control outputs and monitor inputs. The module can operate in balanced or unbalanced mode.

• Supports time stamp events
• Supports time and data synchronization from a master or the processor
• Supports monitored data
• Event queue supports 99 points for each data type
• Reports events by configurable priority order
• Order monitored points by interrogation groups
• Configurable deadband for monitored measured points
• Supports Master Class 1 and Class 2 polls with configurable parameters
• Acknowledgement transmission is handled internally by the module
• Configurable data link address, Common ASDU address and Information Object Address
• Configurable pulse duration.
