shanmugam Posts: 25 Rating: (0)	Dear Wizard, Actually in my project i was done with a software redundncy by using FB523,In hmi side i had created two tags for the both cpu, cpu 1 i have assigned(db1.dbb4) change conection limit tag setting are below, 1.upper limit is setted zero. 2.in event>>higher limit>>change connection:PLc_changer address =192.168.1.1 slot =3 rack=0 cpu 2 i have assigned(db1.dbb5) change conection limit tag setting are below, 1.upper limit is setted zero. 2.in event>>higher limit>>change connection:PLc_changer address =192.168.1.2 slot =3 rack=1 when cpu1 as a master(db1.dbb4=1, db1.dbb5=0) when cpu1 as a master(db1.dbb5=1, db1.dbb4=0) evry thing its happinig in my logic: => when cpu1 is live(power_on) and cpu2 is dead(power off) condition,cpu1 will be communicating with MP377 =>when cpu2 is live (power _on) and cpu1is dead(power_off) condition ,cpu2 will not be communicating with mp377,here i think connection change over is not happening.. how to check my project redundany is working or not?how it works? please give solution to solve the redundancy issue due this problem my project was got delay... best regards shan
