I try to design everything so that the PLC can continue to operate the process even if the HMI dies. The way I look at it the PLC is doing the work and the HMI is the part that tells you what is happening. Some of it I learned by doing it and realizing what makes my job more difficult or makes things work better for the customer. Is anyone intricately familiar enough with the FactoryTalk View Studio ME datatype inference? I'm wondering if for some reason it's not taking it as a string and if I could some how format variable #147 as a string datatype to get this to work without extra tags. The only problem is I'd prefer to avoid creating that many more tags just to contain the same value as the tag name so I guess my question is: Additionally, if I create a system tag in the HMI file then it also works.

The weird part is that if I assign #147 a controller tag that is a string variable type and contains the string A03_MANUAL_MODE it works just fine. The #147 is the string I put in the Global Object Parameter Values section of my Global GoToDisplay button which opens the display with the macro button on it. My problem is that when I put the name of the macro into my GoToDisplay's Global Object Parameter Value in the following formats, it doesn't work:įailed to resolve item's ID 'A03_MANUAL_MODE' because it does not exist on any server. Since this faceplate is variable I'm trying to use the 'Use variable Macro' feature. One of the objects on the faceplate is a macro button. That object accepts values for another faceplate I've created. I have a global object that is a GoToDisplay button that calls up a variable 'Skid' display which contains.
