IEC
60870-5-101
The IEC 60870-5-101 standard is derived from the IEC 60870-5
protocol standard definition. In the Allen-Bradley 865 devices, IEC
60870-5-101 communication protocol is available via menu
selection. The Allen-Bradley unit works as a controlled outstation
(slave) unit in unbalanced mode.
Supported application functions include process data transmission,
event transmission, command transmission, general interrogation,
clock synchronization, transmission of integrated totals, and
acquisition of transmission delay.
