The CLX_offset is the offset into the data for the connection. You can select the offset
where the data is located or you can leave it blank and AN-X will automatically assign
the offset.
The Genius_location consists of an address in the form bSBA where SBA is the 2-digit
serial bus address (SBA) of the module on the Genius bus, from 1 to 31.
Controlling Program Mode Behaviour
The ControlLogix processor that is the exclusive owner of the connection to the generic
module in slot 0 controls how the AN-X2-GENI module scans the Genius 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 to slot 0 is stopped or inhibited, the AN-X
stops scanning all devices on the Genius network. 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 ScanGeniProg in
the configuration file. This causes the AN-X2-GENI module to continue to communicate
with the Genius network when the ControlLogix processor is in program mode but set all
outputs to 0. 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 Genius network.
WARNING!
This option is included for debugging since it allows inputs to update in
the ControlLogix. 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.
If you create the ControlLogix configuration automatically when you autoconfigure the
Genius network, these items are mapped by default to ClxSlot 15.
TIP
If you map the diagnostic data to a separate connection, use a long RPI
to reduce the Ethernet traffic, since the diagnostics do not need to be
updated as frequently as I/O data.
