You can also write a shell script to do it and not tie up the DM.
#!/bin/sh
LOGS=3D/opt/myScripts/logs
mkdir -p $LOGS
exec >$LOGS/`basename $0`.$1 2>&1
set -x
/opt/fox/bin/tools/omset -b T C1:B1.P1 C2:B2.P2
sleep 2
/opt/fox/bin/tools/omset -b F C1:B1.P1 C2:B2.P2
Save it as:
/opt/myScripts/scripts/Pulse
Invoke it as:
dmcmd run /opt/myScripts/scripts/Pulse
Good things should happen.

You can do the following in Foxview to do multiple momentary contacts=20
with a few issues.
1) configure the ACTION as a Display Command
in the Command String Window
setb C1:B1.P1 1
setb C2:B2.P2 1
sleep 2
setb C1:B1.P1 0
setb C2:B2:P2 0
This will set both C:B.P high for 2 seconds, then set them low=20
again. The equivalent of a timed momentary contact in the old DM.
HOWEVER ! Sleeps put the entire display to sleep for the 2 second=20
interval, so no values update, and nothing else can be picked during=20
the sleep time. We have used this (judiciously) in special=20
instances. Not a great solution, but a good stop gap workaround.
Regards,
David
