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:
Offset Description Length
0 -9000 1
1 -9000 1
2 to 7 Backplane Setup 6
8 to 32 Port 1 Configuration 25
33 to 57 Port 2 Configuration 25
58 to 63 Spare 6
Blocks -6000 to -6003 and -6100 to 6103, Master Command List Data for ports 1
and 2, respectively:
Offset Description Length
0 -6000 to 6016 and -6100 to 6116 1
1 -6000 to 6016 and -6100 to 6116 1
2 to 11 Command Definition 10
12 to 21 Command Definition 10
22 to 31 Command Definition 10
32 to 41 Command Definition 10
42 to 51 Command Definition 10
52 to 61 Command Definition 10
62 to 63 Spare 2
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:
Offset Description Length
