MP280 Datasets not communicating
I have an MB300 network with multiple MP280 nodes. The datasets in one node recently stopped communicating with other nodes. All other nodes Datasets work ok transmitting datasets between themselves. The faulty node is communicating with the Masterview so the MB is ok. Why are datasets not communicating from this one node only?

The most common problem is if a member of the dataset table has been removed (e.g. using the DINS command) causing a "hole". If this have happened you may have to dump source code and retranslate it back again to "fill" the hole. Unsure if CRDB reuses "holes" or not.
Run ANPER Channel Load Utilization analyze for a minute, then check if you have any activity on the CXADSx (=DataSet) channels.
Check the CXAA000 task to be running (not listed as "Dormant" in status) using the LTI command (LTI CXAA000) part of the expert command processor set. If it is not running you could try to start it with ACT (ACT CXAA000).
A warmstart (ECONFIG/DICONFIG) is the official method to start up all necessary tasks.
Be observant on any system messages emitted when you attempt to start.
Probably, you should file a support case with your regional ABB support center to get professional assistance.
