Settings for IEC 60870-5-103 communication
The general settings for IEC 60870-5-103 communication are the following:
•
SlaveAddress and BaudRate: Settings for slave number and communication
speed (baud rate).
The slave number can be set to any value between 1 and 254. The
communication speed, can be set either to 9600 bits/s or 19200 bits/s.
•
RevPolarity: Setting for inverting the light (or not). Standard IEC 60870-5-103
setting is On.
•
CycMeasRepTime: See I103MEAS function block for more information.
•
EventRepMode: Defines the mode for how events are reported. The event
buffer size is 1000 events.
Event reporting mode
If EventRepMode = SeqOfEvent, all GI and spontaneous events will be delivered in
the order they were generated by BSW. The most recent value is the latest value
delivered. All GI data from a single block will come from the same cycle.
If EventRepMode = HiPriSpont, spontaneous events will be delivered prior to GI
event. To prevent old GI data from being delivered after a new spontaneous event,
