CHAPTER 3 CREATING PANEL APPLICATIONS
3.6. Command Block and Status Words
Your can command the panel to do a variety of things using the command block. The command block is a block of words in
your controller or the internal memory. The panel scans the control block periodically and performs the specified
operations according to the contents of the control block. You can decide the size of the command block, the command
words that are required in the command block, and the rate of scanning the command block, so the overhead of reading
the command block is minimized.
The panel can provide its status information to you by writing status values to the status words. The status words are in
your controller or the internal memory. You can decide the status words that are required for your application so the panel
will not waste time to output useless status values.
