Hello everyone, I'm trying to write a safty tag from the designer, and I'm encountering this error. The connection to the PLC is good, and there don't seem to be any issues with that. Any suggestions for a fix? Thanks.
I strongly discourage you from interacting with safety code/data in any form via Ignition. It is bad practice and is likely a sign of a bad overall architecture.
SCADA is not a tool for any form of safety interaction.
If you need to monitor tags to show status, there is an entire system for mapping values to non-safe areas of the PLC that are better to read from.
As far as writing from SCADA to a safety routine? I am struggling to think of a use case where it would be appropriate.

GuardLogix specifically prohibits any writes of any kind to a safety tag outside of a safety routine. The only exception is using the safety tag mapping table where you can map a standard tag to a safety tag.
