Hi, I would like to know in case of interupt i.e. calling OB 121 where is db register saved? Is this accessible by program instruction? I suppose you already imaging where I am heading... Having trouble to discover which of db have been called when OB 121 was call. There has been writting about OB 121 but not usefull in case when error occur in dynamic calling of the function and only in the time when plant is working not the case when is down time.... Anyone know some trap to make it and read what has been last call before call of OB 121? The programing is for s7-300 as known there OB register is not very helpfull. Thanks anyone for the help, best regards J. ------------------------------------------------------------------------------------------ |
