Problems downloading program at Freelance

Greetings sirs/madames from ABB,

I receintly had problems doing the download for two AC900 Controllers. The controllers have two independent Profibus networks and share a common Industrial Ethernet Switch. Randomly, the discharge presents problems, having to stop the two PLCs, reseting the PLCs and stopping the communication with the Workstations.

Please help me answering these questions:

1. What is the cause of this fault?

2. Is this fault related with network connections or earthing?

3. Is the fault related with memory restriction of the controllers?

4. How can I solve this problem?

Regards.

Hello,

From the first image it could be because of memory restriction and there PRAM and number of objects needs to be changed. be careful anychange here need controller full download(cold start).

But from second image error code ffff0104, Check in controller logs, this goes into fatal error history ? or when this error appears F(Failure) LED litup contantly RED ?

Strongly suggested to register a case via your local/regional L3 Support center.
