7. If the conditional contact is not enabled, there is no pulse output.
8. When the on-line editing is used, please reset the conditional contact to initialize the
instruction.
Example:
When the program is executed, the values in D0 and D2 are 1000 and 2000 respectively. When
X0.0 is ON, the pulses illustrated below are output from Y0.0. When X0.0 is OFF, Y0.0 is OFF.
