Hi,
Remove the 'poll rate' from your Modbus object, and connect a Switch to the 'Poll' datamember.
The object will now poll, and hence dial, only when you flip the Switch.
If you however want to stay connected after dialing, connect another switch to the OffHook datamember to do this. Flip the Switch off to not stay connected.
Rgds,
Khalid 🙂
