Communication monitoring
Communication with the slave devices is constantly monitored. The monitoring is
activated as soon as the device is selected (basic configuration).
If the communication with the device cannot be established or gets lost, individual
alarm is triggered:
● B-Alarm "3005: I/O extension module, Modbus communication error"
● B-Alarm "3011: Duct pressure sensor, Modbus communication error"
● Configurable "3012: Supply air fan, Modbus communication error"
● Configurable "3013: Exhaust air fan, Modbus communication error"
An adjustable delay time to avoid false alarms due to short disturbances can be
configured.
