Take care in software redudant that, you can not use any S5 timers and counters. you can only use IEC timers and counters available in your Library. The programming has to be done in a such a way that your DB follow a consecutive numbers and you do not jump db numbers. The switching time depends upon your User program so take care of that. The software redudant system is given in place where the process is not time critical, where few minitues of plant down shall not affect the process. Have fun....
