Offset Parameter Description
15 Session Count This word contains the number of session configured in the module.
16 Current Cmd This word contains the index of the current command being executed
in the command list.
17 Cmd Busy Flag This word is set to zero if no command is currently being executed and
waiting on a response. If the word is set to 1, a command is currently
executing.
18 Cmd Count This word contains the count of the number of commands configured
for the module.
19 Cmd Delay This word contains the command delay counter preset. There is a
fixed delay between each command to permit the module to perform

command list. If the executing command is from the command queue,
the word will be set to 1.
21 Cmd Queue
Count This word contains the number of active commands in the command
queue for the module. Up to 100 commands can be buffered in this
queue. These commands are transferred from the processor to the
module using special command blocks.
22 to 23 Online Status This double word value contains a bit for each of the 32 potential
sessions in the module. If the bit is set for a session in the double
