  1. TIA Portal HMI Button Not working

    1) 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.   How you confirm the HMI tags is match to the PLC Tags. Is it by DB address? You need to make sure the HMI is link to the correct PLC addrrss.   2) 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.   What means corresponding manual control subsequently do not work and the manual control that do work? This mean manual control work or not working?

  4. I guess you could use "Read_Var" and "Write_Var" to read and write.
