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,
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.
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.
In addition there is a setting on each event block for function type. Refer to
description of the Main Function type set on the local HMI.
