Broken io Variables Vijeo Designer
Hi, I am currently working with a Modicon m221 PLC (machine expert v.1.2 SP1 software) and a HMIGTO6310/6315 HMI (Vijeo Designer v.6.2 Software) The old programs were written in prior versions of Vijeo Designer and worked like a charm, after opening an old program in v6.2 it prompted an update to the file and this update seemed to break the communication with the PLC direct IO's.
All variable addresses that are memory allocated, %m, %mw, etc... all work fine. The HMI can read all these variables still but any direct address to IO cards %i, %Q, etc.. All show as a faded value. If I create redundant memory addresses for each io and store the values in memory the HMI can acknowledge the values.
This fix would be sufficient but the program has over 80+ Variables that would need to be rewritten and any old code that needs updated would all need new variables.
I have attempted to import the variables back into the HMI program but that did not solve the Issue. The variables don't show a non connection error, they are just dotted and faded out.
