Write Configuration
This block is sent from the SLC 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 9997 in the first word. The module
will respond with a block containing the module configuration data. Ladder logic
must handle the receipt of the block. The block transferred from the module is as
follows:
M0 Offset Description Length
0 9997 1
1 to 6 Backplane Set Up 6
7 to 31 Port 1 Configuration 25
32 to 56 Port 2 Configuration 25
57 to 68 Port 1 Command # 0 Definition 12
69 to 80 Port 1 Command # 1 Definition 12
81 to 1244 Port 1 Commands # 2 to # 98 1164
1245 to 1256 Port 1 Command # 99 Definition 12
1257 to 1268 Port 2 Command # 0 Definition 12
1269 to 1280 Port 2 Command # 1 Definition 12
1281 to 2444 Port 2 Commands # 2 to # 98 1164
2445 to 2456 Port 2 Command # 99 Definition 12
Ladder logic must process this block of information and place the data received
in the correct data files in the SLC. The processor requests this block of
information using the following write block:
M1 Offset Description Length
7800 9997 1
Warm Boot
This block is sent from the SLC processor to the module when the module is
required to perform a warm-boot (software reset) operation. This block is
commonly sent to the module any time configuration data modifications are made
in the configuration data area. This will force the module to read the new
configuration information and to restart. The structure of the control block is
shown below:
M1 Offset Description Length
7800 9998 1
Cold Boot
This block is sent from the SLC processor to the module when the module is
required to perform the cold boot (hardware reset) operation. This block is sent to
the module when a hardware problem is detected by the ladder logic that
requires a hardware reset. The structure of the control block is shown below:
M1 Offset Description Length
