dear all, In op77B as the software clock is not buffered,everytime i cut power the clock will be lost. it is only possible to synchronize with cpu(in my case cpu is 224xp) to get actual time here i am attaching the s7-200 program where i have set and read the RTC.(please see the attachment first) In that program, tags vw100,vw102,vw104,vw106,vw108,vw110 giving me year,month,day,hour,min,sec in INT data type. now same tags with same INT data type i am creating in wincc flexi and in i/o field i have taken format type decimal but i am not getting date and time on screen instead of date and time it is just showing me ## / ## / ## ## :## : ##. i think this problem is because of data type but i am not sure. please tell me possible solution. thanks in advance.
