Write Configuration Block (-9000)
This block is sent from the PLC 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:
Blocks -6000 to -6003 and -6100 to 6103, Master Command List Data for ports 1
and 2, respectively:
-6000 to 6016 and -6100 to 6116
-6000 to 6016 and -6100 to 6116
Each of these blocks must be handled by the ladder logic for proper module
operation. The processor can request the module’s configuration by sending a
configuration read request block, block code 9997, to the module. The format of
this request block is as follows:
