SFC 1 does not return any specific error information.
The current date and time are available at output CDT.
14.1.3 SFC 2 ... 4 - Run-time meter
VIPA CPUs have 8 run-time meters.
You can use:
SFC 2 SET_RTM set run-time meter
SFC 3 CTRL_RTM run-time meter starting/stopping
SFC 4 READ_RTM read run-time meter
You can use a runtime meter for a variety of applications:
n for measuring the runtime of a CPU
n for measuring the runtime of controlled equipment or connected devices.
When it is started, the runtime meter begins to count starting at the last recorded value. If
you want it to start at a different initial value, you must explicitly specify this value with the
SFC 2.
If the CPU changes to the STOP mode, or you stop the runtime meter, the CPU records
the current value of the runtime meter. When a restart of the CPU is executed, the run-
time meter must be restarted with the SFC 3.
The runtime meter has a range of value from 0 ... 32767 hours.
14.1.4 SFC 2 - SET_RTM - Set run-time meter
The SFC 2 SET_RTM (set run-time meter) sets the run-time meter of the CPU to the
specified value. VIPA CPUs contain 8 run-time meters.
