Does anybody knows this ABB legacy controller?
We have a problem with it. We sugested our client to change this controller because it is very old, but he was very satisfied with it. This controller was working fine without problems during more than 20 years. Last week a power fail ocurred and the controller didn´t start. We have the programs, the tools for program it (MPST) but we cannot communicate with it.
After several tests we think that the problem it is in the EPROMS where the operating system is loaded from. This ERPOMS are deleted.
Nobody in ABB Spain knows about this controller.
Could somebody help us?
