Input POSITION is a double-indication signal, and it is GI enabled. This means
that any state transition, that is to ON, OFF, intermediate and faulty, is reported
spontaneously. However, the intermediate and faulty states may be suppressed by
setting the Report Intermediate Position = Off. See the settings for RS485 and
optical serial communication for more information.
Input SELECT is a single-indication signal, and it is also GI enabled. State
transitions to ON and OFF are reported spontaneously.
When input BLOCK is ON, the function will ignore GI requests and cease all
monitoring activity. Consequently, no transitions will be detected.
The I103POSCMD function is also equipped with two additional commands:
Operate and Cancel. These are hidden in ACT and respond only to base INF +2
and +3 respectively. The base INF (Information Number) parameter is an IEC
60870-5-103 identifier that associates a function in a 103 Master (such as Scada)
with its equivalent in the IED.
