Hello, Is there a way to stop single user defined scan retrying
to poll after timeout?

I need scan to stop, because other scans added to the same master are blocked. Is it possible to disable scans bind to the IMaster  ?

Hi Arturas,

The message you've provided isn't a scan (READ request for data) it's the master asking the outstation to disable unsolicited reporting.

A conformant outstation should at least be able to respond to this request with the FUNC_NOT_SUPPORTED IIN bit.

That said, you can stop the master from sending disable/enable unsolicited messages via configuration:
