  1. TIA Portal HMI Button Not working

    I am hoping someone can help me.   I have a siemens system in our facility that was built by a 3rd party.  It arrived in less than stellar fashion, and doesn't work as it should.   After 10 months of being here and not getting any resolve, I am going after it myself to tackle what should be relatively mundane issues to fix.  That said, I have an AB background, and have worked with Automation direct, eaton, and fanuc controllers.  I am new to siemens.   I have made my way around the ladder pretty well, but I am having some issues with the HMI.  Specifically, the vendor programmed in manual controls for our system, but they do not all work.  I checked the HMI tags; they appear to match the plc tags as I expect, but when I press the HMI buttons on the screen, in online mode, I cannot see the tags become energized in the ladder.   The corresponding manual controls subsequently do not work.  The manual controls that do work, I can see the bits energize when I press the HMI buttons.   Is there anything specifically I should be looking at that I am overlooking possibly?  Typically, the HMI is an easy part of a project, but I am a bit dumbfounded by my inability to figure out something so seemingly simple.     Thanks, KK
