Hello it seems Siemens "forgot" to translate the example program from German mnemonics into English ones. There's two ways to fix this: 1.) change your Step 7 to Germanmnemonics (Options menu->Customise->Language tab), entertheexample program into your OB86 and then change Step 7 back to English mnemonics. 2.) Use the following English mnemonics based commands in place of the German ones: SPBN--> JCN U --> A AUF--> OPN I hope this helps |
Cheers |
