Could someone please comment as to the best way of transferring the OPC variables to S7 and if via a script, how to notate it? Regards, henno2000 |

Hi henno, Yup, you can create DB's on the PLC side and create regular tags in WinCC to read them. For performance issues, you should consider putting all of those tags in the same DB, and in contiguous positions... And you'd create a script (the trigger would depend on your needs) to get and set those tags! Here's some info on the GetTagMulti functions, to read multiple tags... oh... and don't use the GetTagMultiWait functions, since it'll probably mess up the performance! Best regards, Danielle |
