Modbus RTU over RS-485

A wired bus allows several monitors to be brought together, each with its own address, on the same network. A controller or gateway consults the temperature measurements, door status and alarms of each piece of equipment.

Modbus is an open protocol widely used in automation. It makes it easy to integrate supervision with PLCs, management systems and SCADA, without depending on radio communication. Checking messages helps detect transmission errors.

It is a practical option when there is already an RS-485 line or a dedicated bus can be installed and simple integration with other compatible equipment is sought.

open door notice

The 105 dB buzzer warns when the door remains open for longer than the configured time. The delay is programmable to adapt it to the work of the cold room.

The equipment monitors the temperature, the door and the alarms. It does not regulate the cooling or modify the controller setpoint.
