This could be executed by a subroutine before PLC_RESET. With RET the subroutine will be
left.
(*SUBROUTINE*)
ResetCounter:
LD 0
ST M_DINT_MINUTESOLD
ST M_BOOL_RESET
LD 1
ST CTU_COUNTER.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
flag will be reset to 0.
