Frequently Asked Questions

Does it run in a virtual machine?
Yes, connectivity servers run well in VMs; give them stable network access to controllers.

Can it buffer data on network loss?
The data logger can store-and-forward into SQL, covering short outages.

Is a license dongle required?
Licensing is per driver bundle with runtime counts.

Tips from Real Projects

A plant standardized every machine connection through one KEPServerEX instance; when the historian changed, not a single PLC project was touched. The connectivity layer is the firewall between the shop floor and every IT fashion.

Tips from Real Projects

During a packaging-plant retrofit, Kepserver 6.8 paid for itself on the first night shift — three faults that would have stopped the line were caught in the office instead. What worked: force tables prepared before each FAT session, so scenarios could be demonstrated in seconds instead of argued about for hours. One caution from the field: keep the tool and firmware revisions matched to the target controller, or cross-loading a project will silently downgrade instructions.
