This could be executed by a subroutine before PLC_RESET. With RET the subroutine will be
left.
(*SUBROUTINE*)
ResetCounter:
LD 0 (*the old value for operating minutes*)
ST M_DINT_MINUTESOLD (*is set to "0"*)
ST M_BOOL_RESET (*reset the flag for running this*)
(*subroutine*)
LD 1
ST CTU_COUNTER.R (*reset counter by input R*)
RET
(*END SUBROUTINE*)
The call of the subroutine could be executed at the end (after ST M_DINT_HOURS). Therefore
the flag (M_BOOL_RESET) must be set to 1. Instead of the flag an input address could be
used, for instance a command.
Reaching the command CALC the call of the subroutine will be executed. In the subroutine the
flag (M_BOOL_RESET) will be reset to 0, otherwise the counter would last at 0 as long as the
flag will be reset to 0.
LD 0 (*besides reset of the time the*)
ST CTU_COUNTER.R (*counter input R is set to "0"*)
LD M_BOOL_RESET (*if the flag is set to "1"*)
CALC ResetCounter (*call the subroutine ResetCounter*)
