These clock signals are used in the user programs, toggles on/off
every half cycle. The clock signal can be delayed or distorted in
accordance with program execution time as the signal toggles
after scan has been finished, therefore, it is recommended that
clock of enough longer than scan time be used. Clock signals
starts from Off when the initialization program or scan program
starts
•
Example: _T100MS clock

Usable in user programs.
_1ON *
BOOL
−
First scan On
Turn On only during the first scan after the operation has started.
_1OFF *
BOOL
−
First scan Off
Turn Off only during the first scan after the operation has started.
_STOG *
BOOL
−
Scan Toggle
Toggles On/Off at every scan while a user program is being
executed. (On at the first scan)

Program
Complete
If this flag is set to on in the initialization program in an user
