Modbus communication allows Flair 23DM relays to be connected to a supervisor or any other device with a master Modbus communication port. Flair 23DM is always the slave. Accessible data: Modbus communication can be used to perform functions remotely such as:  Reading of measurements, counters and diagnosis  Reading of status conditions and remote indications  Transfer of time-tagged events  Reading of Flair 23DM identification  Time-setting and synchronization  Reading of settings  Remote settings when these have been enabled
