Hi all!
I'm seraching for the best solution for that:
I have several modbus tcp relays connected to LM via wifi. Due to non stable wireless connection rarely, when I write a new value to mapped object, relay doesn't change the state. It's clear, that telegram simply does not reach the relay, but new value is correctly stored in LM's database.
Do I understand correctly, that we need to check a relay state periodically (or after writing new object value) and compare it to the object value? And in case of different values write the correct value to the bus again?
Thx!
