Your scripts contain numerous tag reads, often you are reading the same tag several times in the same script. Therefore I would recommend that you use GetTagMultiWait at the start of the script to write the tag values into a set of variables and reference these variables in your script. This will speed up the tag requests as you are making only one request to the DataManager and consequently should speed up your script. Also it will prevent the need to have multiple requests for the same tag.

GetTagMultiWait allows you to request multiple tags in one go and is usually beneficial when requesting large amounts of data from tags. You can find the format definition and an example in the WinCC manual.

Please try this and let us know how you get on.
