8 APPLICATION INSTRUCTION
8.25 Timing Check Instruction
713
8
• The counted number of scans is stored among SD8330 to SD8334 in accordance with the special relay of the timing clock
output destination specified by (d).
• The counted number of scans stored among SD8330 to SD8334 is reset when the counted value reaches "(n1)+(n2)" or
when the command input (instruction) is set to on.
• When the command input is set to ON, the operation is started. The special relay of the timing clock output destination is
set to ON or OFF by the END instruction. Even if the command input is set to OFF, the operation is not stopped. In the
STOP mode, the operation is stopped. When the power to the CPU module is turned OFF, the operation is stopped.
• When (n1) and (n2) are set to "0", the status is as shown below:
• The table below shows the related devices.
Precautions
• The DUTY instruction can be used up to 5 times (points). It is not permitted, however, to use the same timing clock output
destination device for two or more DUTY instructions.
