Note: If the ControlLogix processor previously had a connection open to the QTS-CLX-
PVX module when the autoconfiguration timed out, that connection remains open, even
though there is now no configuration on the module. However, if the module has no
configuration, itwill not accept new connections.
WARNING!
If the configuration in the PROVOX controller changes, you must repeat
this procedure to capture the new configuration. Failure to do so results
in the monitored values being incorrect.
Card and Data Limits
The QTS-CLX-PVX supports a maximum of 64 cards in monitor or master mode. If
there are more than 64 cards in the captured configuration, ClxPvxCfg displays a
message. You will have to delete some cards from the configuration. Right click on the
card and select Delete.
Note: You cannot delete a 10 Series Communication Card. It disappears automatically
when you delete all the other cards in the file.
In addition there are limits on the amount of available ControlLogix data space.
Depending on the type of cards, you may exceed one of these limits without exceeding
the maximum of 64 cards. In monitor mode, you will have to remove some cards from
the configuration or use two QTS-CLX-PVX modules as monitors. In master mode, you
can split the bus and use a QTS-CLX-PVX master on each bus.
Monitor-Only Files
A monitor-only file is created under two circumstances:

the captured configuration contains an unsupported card type
 a card in the PROVOX controller’s configuration is not responding on the bus
A monitor-only file can be used with the QTS-CLX-PVX in monitor mode but cannot be
converted for use in master mode.
Mapping the I/O Data
When you autoconfigure the monitor from the PROVOX bus, the configuration tool
automatically maps the I/O data to locations in the ControlLogix scheduled input and
status input data.
When you change the module to master mode, the configuration tool remaps the data to
ControlLogix scheduled input and output data.
If you delete any cards from the configuration, all mappings are cleared. Unassigned I/O
addresses are shown as Undefined in the tree. To remap the data, select Actions/Auto-
allocate Logix Addressing.
WARNING! Whenever the data mapping changes, make sure you export a new alias
file and re-import it into RSLogix 5000 so that you are using the correct
