Command Control Blocks (5001 to 5016)

Command control blocks place commands in the command list into the command

queue. The client has a command queue of up to 16 commands. The module

services commands in the queue before the user defined command list. This

gives high priority to commands in the queue. Commands placed in the queue

through this mechanism must be defined in the module's command list. Under

normal command list execution, the module will only execute commands with the

Enable parameter set to one. If the value is set to zero, the command is skipped.

Commands may be placed in the command queue with an Enable parameter set

to zero using this feature. These commands can then be executed using the

command control blocks.

One to six commands can be placed in the command queue with a single

request. The following table describes the format for this block.

The last digit in the block code defines the number of commands to process in

the block. For example, a block code of 5003 contains 3 command indexes that

are to be placed in the command queue. The Command index parameters in the

block have a range of 0 to 15 and correspond to the module's command list

entries.
