Module Configuration
This block is sent from the ControlLogix processor to the module to force the
module to write its current configuration back to the processor. This function is
used when the module's configuration has been altered remotely using database
write operations. The write block contains a value of -9000 in the first word. The
module will respond with blocks containing the module configuration data. Ladder
logic must handle the receipt of these blocks. Refer to Configuration Data (page
27) for information on configuration data requests.
The blocks transferred from the module are as follows.
