Is there a way to force an MBregisterV2 or similar object to query the MODBUS slave while still leaving the updatePeriod at zero? I need the forced query while the object and its parent screen are already enabled without enabling automatic querying (i.e. without setting updatePeriod to non-zero).

I have been able to force the queery by re-enabling the object by setting enabled to true (even though it is already enabled). I am wondering if there is a more proper or direct way to do it.

There is not a Query method. I think what you're doing is the best approach.

Forcing query by re-enabling works as you suggest. Thank you.
