4.7 Sequence plans for the programmer
The following sequence plans will assist you in programming
a higher−order PLC/IPC. They show you how to:
 create readiness to operate
 start NC records in Record Select mode
 start NC programs in Start/Stop mode
 quit faults.
The signal names are printed in upper case letters. For
example: READY stands for the READY signal, 1
stands for the
1 signal, 0 stands for the 0 signal.
4.7.1 Creating readiness to operate
When the power supply is switched on, the SPC200 performs
the initialization and self test of the connected modules. This
initialization phase can take a certain amount of time, de
pending on the equipment fitted on the system (max. 10 s).
Please note
During this initialization phase no further rising edge may
be generated at the START/RESET input.
After the initialization phase there may be a fault (e.g. hard
ware fault), even if the R EADY output supplies a 1−signal for a
short period. You must therefore wait a further ţ 100ms after
the first recognition
of the 1−signal at the READY output. The
signal at the READY output must then be scanned once again
for a 1−signal (see Fig.4/15 and Fig.4/16; Sequence plan
Creating the readiness to operate").
