I need to control my objects and I thought that I used it as one comand tag from HMI for save space... I hope you understand my question Thanks for reply Regards

There is "Struct_typ" (as I need)...also it is in Input area (I had it in InOut - but i think it is the same...?) but if I loaded my project to CPU then I have error. If I move my "Strcut_typ" to static area - problem has gone but I cant control my object. I am using CPU 315-2 DP and STEP7 proff V11. May I have the "Sturct_typ" too long? It has 7 bytes (2x Int & 3x8 bool). Any idea? Thanks

Although is not there(in struct) any Input or Output variables but it is working. We simply read and write to static variables. If it is placed in InOut we havent any response from PLC and our textlist show us "lost communication" as value "0" in inteeger. Problem with controlling object was we had not rebuilded software cause we are using faceplates and inner connections was some damaged. We are dealing with this problem again today, cause 2nd FB (we will have cca 50 FBs) with this structure responds very slowly. I think we will do two structures(for input and output variables) and maybe it will work. I let you know how it working Again I hope you will understand my English and my idea
