When the trigger bit (I103CmdExecute1) is set, the module will build a block
9901 with the command contained in the first command of the I103Cmds[ ]. The
module receives this block and builds and sends the command to the specified
control device. The data for the command element in the I103Cmds array is
shown in the following illustration.
The following rung displays ladder logic to build a 9902 block to place commands
2 and 3 of the user command list configured in the module's command queue:
When the trigger bit (I103CmdExecute2) is set, the module will build the block
9902 in the output image. The module will receive the new block and place the
commands into the command queue for execution.
