I had to change the slave ID to 2 in order for the Homeseer ( Master ) to communicate with the Micro820 ( Slave ). The address would correspond to the address in the micro820 that I mapped to it. Still have not managed to get a register working yet. Will keep you posted.

No never was someone else was trying to. I am trying to get a register working so I can use it to tranfer the state of my dsc alarm system to an allen bradley micro800 series plc using modbus registers. the modbus plugin stops working about every 3 minutes and cant seem to get a register to work either.

WHYME Now I understand. Sorry. I initially had the problem of the modbus plugin stopping every few minutes. I changed the polling to once a minute and the problem went away. This is on the Modbus tab of the gateway device. It's worth a try in case you have a polling time that's longer. It's not the modbus plug-in that was stopping in my case, it was the unit I wanted to poll. Its Modbus access would shut off after two minutes unless it was polled.
