Write-Property Traffic

Overview

• Writing data to another controller. Writing to an object to do an action.
• Checks for excessive writes to any object.
• For security reasons, you shouldn’t have a lot of writes.

Why it fails

• Misconfigured programming – devices doing Write-Properties unnecessarily.
• Incorrect data exchange.
• Bad device selection (e.g. device with output doesn’t have programming space).
• A configurable device has an output on it.
• Cybersecurity attack.

How to fix it

• Identify who is sending the Write-Property traffic.
• See if you can change the write to a read.
• If not, reduce the amount of Write-Property traffic.
