I have a switch connected to a Modbus Write coil where it is only working once its in the "active" stage (que-reconnect-initialize-connected-active). At every other stage sending a 1 or 0 out would get missed. Is there maybe a que option where it would make sure it gets sent out once its active again?

Dig around in the advanced settings of the config node, pretty sure there is a queue option there somewhere.

There is a que option, but how would I que a boolean value until the write coil modbus becomes "active" thanks

The node should queue the request until the connection is working.
