Offset Parameter Description
20 Cmd Count This word contains the count of the number of
commands configured for the module.
21 Cmd Delay This word contains the command delay counter
preset. There is a fixed delay between each
command to permit the module to perform class
polls on controlled stations.
22 Cmd Queue This word is set to zero if the command executing
is from the command list. If the executing
command is from the command queue, the word
will be set to 1.
23 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.
24 to 25 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 word, the station
is online. If the bit is clear, the station is offline.
Use this value to determine if commands sent
from the processor will have a chance of
succeeding.
