AN-X2-GENI (AN-X-GENI/B)
May 2013
Using Ghost Mode
In ghost mode, the AN-X2-GENI monitors inputs and outputs on an existing Genius
network and passes the monitored data to a ControlLogix via scheduled connections.
Ghost mode is useful when the AN-X2-GENI and a ControlLogix is to replace an
existing control system and you want to verify the data and timing on the existing system
before replacing it.
WARNING!
You must be careful in setting up ghost mode that you do not disrupt the
existing sytem when you connect and configure the AN-X2-GENI
Configuration is best performed when the existing system is connected
but is not running.
The AN-X2-GENI requires an available serial bus address on the Genius network.
You can use the autoconfiguration feature of the AN-X2-GENI to locate all the devices
on the network and generate a starting Genius configuration file.
Genius Configuration File
You must configure the Genius I/O on the network being monitored. The configuration
file format is the same as described earlier (see page 18). Ensure that the Scan field is
removed from all Genius devices so that the AN-X2-GENI doesn’t write outputs to the
network.
ControlLogix Configuration File
The output data on the Genius network is mapped to ControlLogix scheduled inputs.
Data definitions for the monitored outputs consist of lines that define the mapping of the
Genius output data into the ControlLogix data table.
They consist of lines of the form
CLX_offset (optional), Genius_Location, tagname
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
msourceSBA>destSBA[length]
where
sourceSBA is the serial bus address (SBA) of the module on the Genius bus that is
sending the data
destSBA is the serial bus address of the destination
