Note
If you select incorrect parameters when setting the system time,
and if the time has been set correctly at least once, the error IDs
are transferred, however, the previously set system time is
retained.

"Setting the time"
You want to set the system time as follows:
"Thurs, 24.11.1991, 11:30, 0 seconds, 24 hour format"
It is assumed that the time parameters will be stored in data block
DB 10 from data word DW 0 onwards. The system time should be set
accurate to the second by triggering a process interrupt (trigger bit,
e.g. I 1.0 - button in the vicinity of the PLC).
First, program data block DB 10 with the following values and load it in
the PLC. You must include the STEP 5 operations for calling OB 150 in
OB 1 in such a way that the operations for calling OB 151 are only
executed in the case of a rising edge of the trigger bit:
