IEC 60870-5-103 Master Network Interface Module for PLC

The MVI71 IEC 60870-5-103 Master Network Interface Module allows PLC processors to interface easily with IEC 60870-5-103 Slave devices. The MVI71-103M module interfaces up to 32 serial communication devices with the 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. The MVI71-103M is the ideal solution for many applications where IEC-compatible devices must communicate with the PLC platform. Compatible devices include relays, breakers, sub-station communication modules and other serial communication devices. Functionality of the IEC protocol is very similar to the DNP 3.0 protocol which features time stamping and True Report by Exception (TRBE). These features allow the MVI71-103M module to send a report to the processor without being polled, providing real time data transmission in critical situations.
