Hello everyone, I need some help in configuring ob13 to be called every 1 second. I tried using an example in the siemens manual but the cpu kept going into stop mode. The manual said to tranfer value to BS97. The cpu wouldn't allow this. So I put the following in ob21 & ob22. L kf+100 T SD97 BE I'm not sure the SD is right for the system data word. I know sometimes in the Siemens manual they use the German mnemonics instead of english. Any help appreciated!!
