Is there a way for the DT80 to set up a schedule to log the state of the latching relay and have it displayed on the LCD screen? I am setting up the unit such that the latching relay will be toggled by writing to the MODBUS register for it.

Unfortunately, I have not been able to set up a schedule to log the state of the relay in the unit itself. Any help on this would be appreciated.

Good morning ral,

Yes there is. The relay has a channel definition just like any other dataTaker channel type. If you want the current state of the relay then 1RELAY will return the state. One you have this command in the channel list it will appear on the display.

In DeLogger you will need to us the User channel type to read the state.

Cheers,
Roger
