I think I now better understand why Siemens has had such difficulty gaining market share in the US. Their product is robust and flexible, but often terribly counterintuitive and unfriendly.
Here's another dummy question. I have searched to the ends of the earth and cannot find where the scaling function in the Siemens HMI is. My co-workers tell me it does exist, but will not tell me precisely where it is located in the HMI programming interface (hazing the newbie of course). Google gets me nowhere, just like the Siemens support website.
Good grief Siemens support is just horrendously bad. If you don't have a co-worker to show you what you need to know you are really and truly on your own to somehow intuit your way through the pitch black fog, which often means literally guessing your way through some of the most arcane interfaces and terminology I have ever seen in my life.
Thus far, simply refusing to give up has been my only consistently effective survival strategy.
