The IEC 60870-5-101 Master Network Interface Module allows Quantum compatible processors to interface easily with IEC 60870-5-101 slave (controlled unit) devices. Typical applications for this protocol include power distribution. water treatment. lighting systems for highways. etc. Originally developed for the Power Utility industry. the IEC 60870-5 protocols are very similar in function to DNP 3.0. Both protocols offer Report by Exception functionality and dating of events (time stamping).
