PROTOCOL-SPECIFIC INFORMATION
Register
The inverter register number (refer to section 4) that the BACnet object's present value will access.
Bitmask
Specifies which bit(s) in the 16-bit value designated by the "Register" that the binary object will map to.
This mechanism allows up to 16 binary objects to be simultaneously assigned to one register (each
binary object mapping to a single bit of that 16-bit word). It is possible to map binary objects to multiple
bits within the designated register.
The effect of the "Bitmask" field when reading: When the present value property of a binary object is
read by a BACnet client, the bitmask is used to determine the active/inactive state of the object by
inspecting the value in the designated register at the bit location(s) indicated in the bitmask. If all of the
bit locations at the designated register are set, then the object's state will be returned as "active". Else,
the object's state will be returned as "inactive". This resultant state is reversed prior to being placed on
the network if the object's "Polarity" is set to "Reverse".
Active Text
Specifies the description of the object's "active" state. Enter a string of up to 32 characters in length.
This field is optional and may be left blank.
Inactive Text
Specifies the description of the object's "inactive" state. Enter a string of up to 32 characters in length.
This field is optional and may be left blank.
