Word two of the block can be used by the ladder logic to determine if the
command was added to the command queue of the module. The command will
only fail if the command queue for the client is full (the queue can handle up to
100 commands for each client).
Command Control
Command control blocks place commands in the command list into the command
queue. Each client has a command queue of up to 100 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 or two. 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 format of the block is displayed below:
