Prompt Time Sequence
•
Bit 13 in the status word is set after the prompt time has elapsed.
•
Bit 13 remains set until you reset it in the control program.
•
The prompt time can be read at any time.
Caution
!
If the prompt time is reached in the STOP mode or during Power OFF, the prompt time
cannot be evaluated. It is always deleted on restart.
Example:
Setting and evaluating the prompt time
In the example program, the status of input I 0.6 determines whether the settings for the prompt time
are transferred. Before setting input I 0.6, you must transfer the settings to flag bytes FY130 and
FY135. Enter values that you do not wish to be evaluated as FF
You set the clock mode with input I 1.0. Use input I 0.1 to specify the the AM/PM bit for 12-hour
mode.
If the preset prompt time has been reached, set flag F 13.2. If errors are made while entering the
prompt time, the error bit, flag F 12.2, is set.
The clock data is stored in DB2 beginning with data word DW0, and the status word is flag word
FW10.
