Hello guys,

I have one little problem with transfer data in DBxx

I structured DB with array 0..50 with 110bytes(words) and every conditioned cycle transfer data from DBxx.Position[n] to DBxx.Position[n+1] .... this right run without any problem

Now I increase array to 0..80 (total 8910 bytes) and transfer data not correct running

Now my question:

Is some condition for maximum transfered bytes inside DB´s per one cycle of CPU ???

I tried decrease array to 0..75 (total 8360 bytes) not correct running

If I decrease array to 0..74 (total 8250 bytes) transfer of data running correct ??? WHY ???

Have anybody some idea for this ??

Hello again,

I find answer for me

"the highest memory address in the DB than can be address would be 2^16/8 bytes = 8192"

Thx to all!
