Lost program changes after power off

Hi there,

I met problem with usage of LOGO!8 + HMI KTP700. I change value of yearly timer or counter (with retentivity) by HMI panel. Program in LOGO is changed (I check it by online connection). After that I turn off power supply and after minutes turn on again. Changes of LOGO program made by HMI are lost. Does anybody have idea why?

Here is list of used resources (in LOGO is SDcard because of layout memory):

Still strange - I copy program to SD card, then remove this card and program runs (even better) :)

So memory card is good to use for static program or for logging, is it right?
