ControlNet Objects: Class Code 0x07 — Register Object D-11
Class Code 0x07 — Register Object
The Register Object is used to address individual bits or a range of
bits. It may operate as either a producer (input) register or a consumer
(output) register. A producer register object produces data onto the
network. A consumer register object consumes data from the
network.
Message writes to the Register Object can perform control functions.
Therefore, message writes are only allowed when the controller is not
actively controlling the module and the message write is done through
a connection with a time-out value not equal to zero. Writes cannot be
performed through an unconnected message. After a write, any
time-out or closure of the connection may cause the SCANport
product to fault.
Important: For firmware 1.001, connections to this object are not
supported. Therefore, it is a read only object.

➀
The command word is set to the value of the first word of the data where there are ones in
the second word of the data. command = (word 1 and not word 2) or (word 1 and word 2).
This only controls specified bits in the logic command data to the SCANport product and
does not change the reference value.
