Tjome Posts: 30 Rating: (1)	I get 3 different errors. In diagnsotic messages from CPU ( 315 -2 PN/DP ) it says:. 1. FC NOT LOADED. Requested OB is OB121, and it says that FC number 244 is not loaded. Event ID is 16#253C. But thats completly true. I can not find any FC244 and I can not find any call to FC244 either? Can I find out about message by help of Event ID 16#253C ? 2 IO ACCESS READING ERROR requested OB for that is OB122. P area, byte access. Access adress : 270 Event ID is 16#2942. Only modulethat have "nearby" adress to 270 is CP340 rs232C ( I am not ready with programming that one yet ). Adress in HW for it is 272- 287. 3 AREA LENGHT ERROR WHILE READING Requested OB is OB121, and it says: Global DB, byte access, access adress 27. In witch DB can I find that one? I have DB1,DB2, DB3, DB4, DB5, DB6, DB7, DB8, DB9, DB10 and DB 206. Event ID is 16#2522

Tjome Posts: 30 Rating: (1)	Hi ( again) !!! Yes , I compeare on/off line and was looking for FC244, and there is no. But there is some "other" FC , i thought was deleted !!!! And there was even one FB 3, witchI has rewrite/copy from old S5 applictaion ( it has to to with printer function in old s5) .When I start write "new" S7 text block/function I was delete those " old converted" FB and DB .But, But FB3 was still "online" in CPU. Now Idelited FB3 onlineand it´s OK about FC244, since I do not need FB3. (Instead I got message that FB 3 is missing , but I found that call in OB1) Can I just not restart/clear my CPU byhold down button to STOP and wait for two flashes, and than , quick, once again, until it flash twice fast? And than downlaod it again? Or shall i go online and "delete" everything that way?

Tjome Posts: 30 Rating: (1)	Hi Marcjan. I just do MRES ( but probably wrong since I didnt clean memmory in CPU ), but it was still there. But I delit all OB, FB, PB and DB "manual" when online, by marking everything and pressing "delite". Andthen I did MRES again. Download HW config, and finaly application. Now its gone Now I ( still ) have: IO ACCESS READING ERROR, adress 270

To make a factory reset follow this (requires firmware 2.5 or higher): https://www.automation.siemens.com/mdm/default.aspx?DocVersionId=29564002699&Language=en-US&TopicId=24570788363

I will try that nexttime. Now it ok, but realy good to know - I was doing " my" MRES at least 10 times today ( but I never check online if its realy was "clean", because I was for shure that CPU was cleard each time).
