Mi-k-l Posts: 41 Rating: (1)	Hi, I have a new problem! Always!! I am using the solution above. It works very well on PLCSIM but not on my PLC s7-400. The CPU diagnostic module show me I have an area lenght error in writing. Why? I wrote that: [code]LAR1 P##ptr_dest L B#16#10 T B [AR1,P#0.0] L B#16#2 //ID to implement Byte data type in ptr T B [AR1,P#1.0] L 2000 //Repetition factor T W [AR1,P#2.0] L 240 //DB-num T W [AR1,P#4.0] L "index_archive" //start address T D [AR1,P#6.0] [/code] index_archive increase the address of my pointer every 16000bytes. Where is mmy area lenght error? Greetings, Michael
