5.1.8 Configuration Data Transfer
When the module performs a restart operation, it will request configuration
information from the PLC processor. This data is transferred to the module in a
specially formatted write block when the BTR/BTW interface is used. The module
will poll for the block by setting the Block Sequence Number in the read block to
a value of 9000. The format of the configuration BTW block is shown below:
When the side-connect interface is used, the module will read the configuration
information directly from the specified application user data file. The format of this
file is shown below:
