2.14 SYSTEM_FLAGS
(Module number 151)
System flags are global variables which are permanently integrated into the run-time system. They
include functions that facilitate programming.
The following system flags are included in the 9300 Servo PLC/Drive PLC:
VariableName DataType Address Note
SYSTEM_bClock01Hz %IX151.0.0 0.1 Hz System clock
SYSTEM_bClock1Hz %IX151.0.8 1.0 Hz System clock
SYSTEM_bClock10Hz %IX151.1.0 10 Hz System clock
SYSTEM_bClock0100Hz %IX151.1.8 100 Hz System clock
SYSTEM_bTogCycleTask %IX151.2.0 Toggle marker cyclic task

Tip!
The system variables are not generated in simulation mode.
SYSTEM_bClockxHz
These system flags output a fixed clock pulse with an equal pulse/pause ratio.
• The flag is toggled in real time.
• When you use this system flag, take care with the frequency used for polling the flag (aliasing
effect). You should use at least twice the toggle frequency.
Example:
You would like to use the system flag
SYSTEM_bClock100Hz as a clock for a counter.
• The pulse/pause ratio is 5 msec/5 msec.
• To avoid an aliasing effect, the counter must always be polled with an INTERVAL-TASK
