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

7800 9999 1
