17.3 ZP.CSET (Programmable Controller CPU Monitoring Register/Cancel)
17.3.3 Functions
(1) To register the programmable controller CPU monitoring, this instruction
registers data necessary for the Q series C24 to execute the programmable
controller CPU monitoring function.
When the data registration to execute the programmable controller CPU monitoring function is completed
normally, the Q series C24 begins monitoring the programmable controller CPU and transmitting monitoring
results to an external device.
(2) To cancel the programmable controller CPU monitoring, this instruction ends
the Q series C24's monitoring operation of the programmable controller CPU.
When canceling of the programmable controller CPU monitoring is completed normally, the Q series C24
terminates the operation of the programmable controller CPU monitoring function.
(3) A maximum of 10 blocks can be designated for a word device or bit device to
monitor the device memory.
To register the device memory to monitor, designate the word device blocks for the registered word blocks, then
designate the bit device blocks for the registered bit blocks.
(4) Before sending the programmable controller CPU monitoring results to the
external device, the user frame and user frame number should be registered
with GX Configurator-SC in advance.
(5) To register the programmable controller CPU monitoring once again, cancel
the programmable controller CPU monitoring before registration.
(6) Whether the CSET instruction is being executed or has been completed
normally/abnormally can be checked by the completion device (D2)
designated as a setting data.
(a) Completion device ((D2) + 0)
Turns on at the END processing of the scan where the CSET instruction is completed, and turns off at the next
END processing.
(b) Completion device ((D2) + 1)
Turns on and off depending on the completion status of the CSET instruction.
• Normal completion: Stays off and does not change.
• Abnormal completion: Turns on at the END processing of the scan where the CSET instruction is
completed, and turns off at the next END processing.
