To reboot the module
1 Enter the hexadecimal value 16#9999 in the
PTQPDPMV1_Out_Stat.LastInMailID[0] or the
PTQPDPMV1_OUT_Stat.Setoperatingmode[0] register. The following
illustration shows the PTQPDPMV1_OUT.Stat.LastInMailID[0] control word
variable being used.
2 Add the following Structured Text lines to the program file. These allow the
processor to clear the cold boot command after the reboot, and return to the
normal data transfer cycle.
In order to reset the logic, the program must be written in a way to look for
word 72 in the input status. If word 72 is equal to 16#0099, the logic will reset
the value in PTQPDPMV1_Out_Stat.LastInMailID[0] to 16#0000.
Note: It is normal for the remote (passive) Master in Hot Standby applications to reboot twice
during this procedure.
