Hi Ausman,
Yes i tried, but it didn't work. I couldn't set coil. I read this post https://unitronicsplc.com/Download/SoftwareHelp/VisiLogic_Knowledgebase/Ladder/Operands/System_Operands_(SI)_(SL)_(SB)_(SDW).htm I think I can't use SB53 as output. So my question is, is there other way to assign the function of the Enter HMI button to an input?
Thanks In Advance
