Timers in Multiple Instance Function Blocks

6/30/2006 9:55 AM	Rate (0)
jonsina Posts: 2 Rating: (0)	I have a CPU315-2DP for which I have written a function block which needs to have multiple instances. The function block works fine if only one instance occurs (using say DB100), but as soon as I add another instance (say DB101) then neither work. I have come to the conclusion that it is the timers in the Function Block which are not working as all the other variables appear to be correct. The question is how do I use timers in multiple instances? I have 8 S_ODT timers, T1 to T8, but I guess I must have to indirectly address them some how. Any help would be greatly appreciated.
