4. Start/End Mode:
The default program mode selection for the Relay Module is the
“Start/End” mode. In this mode enter a “start” and “end” node
number and the relay module will activate its relay based on data
from this range of nodes.
Also select how the Inputs and Outputs of the module are to be used
by using the appropriate checkboxes.
After the I/O is configured, determine which events within the
defined group of nodes will trigger the module’s relay. This is done
with the “Trigger Bits” checkboxes.
5. List Mode:
The second available program that can be used by the Relay
Module is the “List Mode.” This mode is accessed by selecting the
appropriate “radio button” from the Relay Module Configuration
dialog box.
When selected, eight data entry fields are displayed in place of the two
used in the Start/End mode. In these eight fields you may enter eight dis-
crete communication module addresses and the relay module will
respond based on data from these nodes. As shown in the example
above, the node addresses can be in any order. I/O operation and trig-
gers are selected by means of the same checkboxes as described in the
“Start/End” mode.
In addition, a “Voting” option can be included. By entering a number in
the voting field, the relay will only be activated when “n” modules from
the list have one or more of the conditions specified by the trigger bits,
where “n” is the number entered into the voting field.
In the example shown above, “3” is entered in the voting field and Alarm
1 and Alarm 2 are the triggers. When either Alarm 1 or Alarm 2 is pre-
sent in at least three modules from the list of eight, the relay will activate.
