Program Mode Behaviour Option
The ControlLogix processor that is the exclusive owner of the connection
in slot 0 controls how the AN-X-MOD (Master) module scans the S908
network. For that reason, when you map the data, you must always
include a connection to the generic module in slot 0.
When the ControlLogix processor with the exclusive owner connection
to slot 0 on the AN-X is in program mode or the connection is stopped,
the AN-X stops scanning the S908 network, just as a Modicon scanner
would. Even if other ControlLogix processors have exclusive owner
connections to other slots on the AN-X and are in run mode, AN-X does
not scan the network.
You can override this behaviour by including a line with the keyword
ScanModProg in the configuration file. This causes the AN-X-MOD
(Master) module to continue to communicate with the S908 network
when the ControlLogix processor is in program mode.
Similarly ControlLogix processors with exclusive owner connections to
other AN-X slots will also update. If the exclusive owner connection to
slot 0 stops, AN-X stops all communication with the S908 network.
WARNING!
This option is included for debugging since it allows inputs to update in
the ControlLogix. It is NOT recommended for normal operation. For
maximum compatibility with Modicon hardware, it should not be used
in normal operation.
Other Mappable Data
In addition to the I/O data, there are other items that can be mapped to
connection input data.
For all these items, you can assign an offset for the data within the
ControlLogix input data, or your can leave out the offset and let AN-X
assign the offset automatically.
