Limit Switches are sensors with an electrical limit control contact output at a specific temperature. Unit allows the user to easily select automatic or manual reset. Applications include gas fired heater limit control and burner control.
- We are trying to program a temperature control and receive the following message - Communication error > address 01: no response from controller at register 795 (031A). What could be causing this error?
- The register 795 is a Modbus register. One of the reasons why there is a communication error is the -992 for the RS-485 communication is LOVELINK Protocol, if you are trying to communicate with Modbus® protocol, it will not work. See the LoveLink™III Software.
