Problem in Freelance controller, DCP10
In our plant, the DCP10 controller of ABB Freelance DCS got stopped while the redundant controller was out of service since long. This resulted to plant operational disturbance.
In an attempt to carry out CPU diagnosis through Hyperterminal using Diagnosis port, EDC unit ----Failed was encountered.
After 5 times attempt, it dispayed, Maximum error count has been reach: further operation will be rejected. With this display, the program got automatically Terminated.
After this, the Failure LED of the CPU glows continuosly in red.
I'm looking to reinstall the DCP10 firmware suitable for EPROM version:8.23 & 1st stage version:F07.100.00. However, I could not find any firmware for DCP10.
Please assist in getting suitable solution.
