BACnet - A Data Communication Protocol for Building Automation and Control Networks
ASHRAE 135 INT 21
Year: 2019
Abstract: This parameter, of type BIT STRING, represents the bitmask that defines the bits of pMonitoredValue that are significant for comparison with values of pAlarmValues.
This value is bit-wise ANDed with the pMonitoredValue before comparison with pAlarmValues
The above statement means that each bits in the BitMask is ANDed with the bit in corresponding position of the pMonitired Value, i.e Present_Value.
This means that the length of the pMonitired Value and Bit_Mask should be same
