(4) Bus Off Counter will be forced to 0 whenever set regardless of the
data value provided.
(5) Allocation_byte
bit 0 explicit – set to 1 to allocate
bit 1 polled – set to 1 to allocate
bit 2-3 reserved (always 0)
bit 4 change of state – set to 1 to allocate
bit 5 cyclic – set to 1 to allocate

Assembly Object
Class Code: 04 (0x04)
The Assembly Objects bind attributes of multiple objects to allow data
to or from each object to be sent or received over a single connection.

16 (0x10) No Yes Set_Attribute_Single
(1) Max Class ID:
Assembly Input Object 101 or TBD
Assembly Output Object 102 or TBD
Max Class ID is the max value of Assembly Input Object and
Assembly Output Object.
(2) Produced Data:
bit 0 = Sensor1 (DIP instance 1 state)
bit 1 = Sensor2 (DIP instance 2 state)
bit 2 = Sensor3 (DIP instance 3 state)
bit 3 = LB/SC Selenoid1 (DOP instance 1 status)
bit 4 = LB/SC Selenoid2 (DOP instance 2 status)
bit 5 = Not Used
bit 6 = Not Used
bit 7 = Not Used
bytes 2-5 = Maintenance counter
bytes 6-9 = Cumulative counter
bytes 10 = Cycle timer "open": in sec
bytes 11 = Cycle timer "close": in sec
(3) Consumed Data:
bit 0 = Not used
bit 1 = Not used
bit 2 = Not used
bit 3 = Not used
bit 4 = Not used
bit 5 = Solenoid 1 (DOP instance 1 state)
bit 6 = Solenoid 2 (DOP instance 2 state)
bit 7 = Reset Counter (UDO instance 1 reset
counter)
Connection Object
Class Code: 05 (0x05)
The Connection Objects manage the characteristics of each
communication connection. As a Group II Only Slave device the unit
supports one explicit message connection, a POLL message
connection.
