Additionally, it listens for general interrogation (GI) requests andreplies to those with a GI response message with the current state of each connectedinput.Input POSITION is a double-indication signal, and it is GI enabled. This means thatany state transition, that is to ON, OFF, intermediate and faulty, is reportedspontaneously. However, the intermediate and faulty states may be suppressed bysetting the Report Intermediate Position = Off. See the settings for RS485 and opticalserial communication for more information.Input SELECT is a single-indication signal, and it is also GI enabled. State transitionsto ON and OFF are reported spontaneously.When input BLOCK is ON, the function will ignore GI requests and cease allmonitoring activity. Consequently, no transitions will be detected.The I103POSCMD function is also equipped with two additional commands: Operateand Cancel. These are hidden in ACT and respond only to base INF +2 and +3respectively. The base INF (Information Number) parameter is an IEC 60870-5-103identifier that associates a function in a 103 Master (such as Scada) with its equivalentin the IED.1MRK 511 408-UUS A Section 19Station communicationPhasor measurement unit RES670 2.2 ANSI 705Technical manual
