Refer to the Modifying the Module Configuration section for a description of the
configuration of the module. The MVI56-DFCMR module must be configured at
least once when the card is first powered, and any time thereafter when the
parameters must be changed.
2.1.1 Changing Parameters During Operation
A copy of the module's configuration data is mapped in the module's database as
displayed in the table above. These values are initialized when the module first
receives its configuration from the ControlLogix processor. Any node on the
network can change this data. A master port on the module may poll a slave for
the data or a slave port could receive the data from a remote master unit. The
module will not use this data until it is commanded. Ladder logic can be written to
issue a Write Configuration command block (9997) to the module. A remote
device can set a value of 9997 at address 7800 (N46:0) in the module to
download the configuration to the processor. Alternatively, the
configuration/debug port on the module can be used to issue the command
directly to the module. All three of these methods will force the module to
download the configuration to the ControlLogix processor. Ladder logic must
exist in the processor to accept the blocks sent by the module. If everything is
configured correctly, the module can receive its configuration from a remote
device.
