Hi, I am facing the same issue, and incidentally it is also with KTP900 Basic. In my case problem is specific with array tags, in PLC there is a DB with an array of Array[0..51] of Int. Elements of this array are set through HMI in IO fields (Low Limit=1, High Limit=359). Whenever the value is set from HMI, it is correctly being assigned to PLC array elements, and also updated/displayed on HMI screen, but after a while, all the array element assigned IO Fields show value "0" and background color changes to orange as it drops below the Low Limit, but when checked in PLC DB values are present and the machine is functioning with correct values. Before reading this thread I thought it has something to do with array assignment, as all other settings which are normal variables in PLC DB memory do not have this problem. But now I am confused because another user faced a similar problem with the same KTP900 but without arrays. Any thoughts on how to resolve this issue?
