Figure 411: 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 Enabled.
• 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, the pending
GI event is modified to contain the same value as the spontaneous event. As a result, the
GI dataset is not time-correlated.
21.5.2.2 Settings from PCM600
I103USEDEF
For each input of the I103USEDEF function there is a setting for the information number
of the connected signal. The information number can be set to any value between 0 and
255. To get proper operation of the sequence of events the event masks in the event
function is to be set to ON_CHANGE. For single-command signals, the event mask is to
be set to ON_SET.
