CTI 2572 Installation and Operation Guide
92
To trigger a coupled mode command for command slot 1 (Assuming the module is logged at Word
1-8):
1. Enter the Command Block data in V memory.
2. Enter the address of the Command Block in WY5.
3. Change the value of WY4 to hex 6000. WX2 should change to hex 2000, indicating that the
module is executing the command.
4. If WX2 changes to hex 2000, set the value of WY4 to hex 0000 (clears the trigger). If WX2
eventually transitions from hex 2000 to hex 0000, the command was executed successfully.
5. If WX2 changes to hex A000, a command error was encountered. Acknowledge the error by
changing WY4 to hex 8000; then clear error acknowledge by setting WY4 to hex 0000. Inspect
the command error word (Command Block - Offset 0), correct the error, and repeat the operation.
6. If WX2 changes to hex E000, you have entered an incorrect address in WY5 or you have an
invalid connection number in the Command Block. Acknowledge the error as described in step 5
above and repeat the operation.
