Hello,

We are using CODESYS 3.5 SP19.70 in an educational environment with several WAGO PFC200 controllers (CODESYS Runtime).

Our campus network is currently configured as a /16, which creates a very large broadcast domain.
We observe slow device discovery and long scan times when opening the network view.

Before restructuring our architecture, we would like to know the recommended network practices for CODESYS:

Recommended broadcast domain size for device discovery

Possible impact of large networks (/16) on scan performance

Usual recommendations (VLANs, /24 segmentation, etc.)

Known limitations or points of attention in extended networks

Any guidance or official recommendations would be very helpful.

Thank you.
