Hi,
I am updating an FB (S7-300 using V5.5), I added positive edge and added a stat variable to local interface, upload, I receive an "area length error when writing" message in diagnostics.
I remember at some point the PLC warned me about uploading the FB with updated interface as can cause PLC to enter STOP, maybe what I clicked turned off the setting to in future not upload the interface?
Please advise what the problem may be and when altering the local interface variables would cause PLC to enter STOP?
Many thanks
