The Integral Real-Time Clock S5-100U
Example: Setting the operating hours counter
The status of input I 0.7 determines whether the operating hours counter values are transferred.
You must transfer these values to flag bytes FY136 to FY140 before setting input I 0.7 (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 data block DB2 beginning with data
word DW0, and the status word is flag word FW10.
