5.2.4 Configuration Data Transfer Blocks (-9000, -6000 to -6004, -
6100 to -6104, 6000 to 6004, 6100- to 6104, and 9000)
When the module performs a restart operation, it will request configuration
information from the ControlLogix processor. This data is transferred to the
module in specially formatted write blocks (output image). The module will poll for
each block by setting the required write block number in a read block (input
image). Refer to Configuring the Module for a description of the data objects
used with the blocks and the ladder logic required.
Write Configuration Blocks (-9000, -6000 to -6004, and -6100 to -6104)
This block is sent from the ControlLogix processor, and causes 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. The blocks transferred from the
module are as follows:
Block -9000, General Configuration Data:
