S5-90U/S5-95U
Integral Real-Time Clock
Example: Setting the operating hours counter
The status of I 32.7 determines whether the operating hours counter values are transferred. You
must transfer these values to flag bytes FY136 to FY140 before setting input I 32.7 (not
implemented in the example program). Values that are not to be changed should be preset with
FF
H
.
Errors are displayed in flag F 12.3. The clock data area is in DB2 beginning with data word DW 0,
and the status word is flag word FW 10.
