Hi Guys,
I am having a major problem trying to find the root of the above error. (Siemens S7) OB121 is called when there is some kind of program error and the code is always an area length read/write fail. The HMI we are using (Micro Innovation Galileo)has tags set as e.g. F(loating point) pointed at a DB Real address or W(ord) pointed at a DB Integer. Comparing some of these tags with older ones I can't see the problem. I just wondered if anyone had come across some similar error. I'm still undecided as to whether the problem is in the PLC or HMI but I'm tending towards S7 for now, that's why I've posted this. I haven't had any luck finding anyone expert at Galileo.
Cheers
TIA
