IBX-Input2
This bit represents the status of the corresponding “open” input on
the IntelliVAC Base. When an IntelliVAC is used in a multi
contactor system this input does not directly open the contactor but is
simply a generic input into the DeviceLogix engine. For further
information see the section detailing LOGICAL MASKS.
Stop Status
This is a dual function bit which can be used to describe the status of
the multi contactor system. In most systems this bit would be set low
whenever any of the contactors in the system are closed and set high
only when all contactors in a system are open. The bit would then be
communicated via network to give an indication of the status of the
system to a remote computer or PLC.
Interim 1-5
These are dual function bits which can be used for any purpose the
user desires.
MC Start Status
This bit has a similar function to the recommended use of the stop
status bit. It is “1” if any of the contactors in the system are closed,
“0” only when all contactors are open.
Start
This is a dual function bit which can be used to represent the status
of the “START” push button, or other form of start command such as
a network input.
Stop
This is a dual function bit which can be used to represent the status
of the “STOP” push button, or other form of stop command such as a
network input.
FWD
This is a dual function bit which can be used to represent the status
of the “FORWARD” push button, or other form of forward
command. This command would be used in a reversing starter.
REV
This is a dual function bit which can be used to represent the status
of the “REVERSE” push button, or other form of reverse command.
This command would be used in a reversing starter.
