Example pricing scenario:
Takeaway: Enterprise is roughly 3x the cost of a standalone system. Only pay it if downtime costs justify it. kepserver enterprise vs kepserverex
| Feature | KepserverEX (Standard) | Kepserver Enterprise | |--------|----------------------|----------------------| | Deployment | Single Windows instance | Multi-node, load-balanced cluster | | Failover | Manual or basic third-party tools | Automatic, built-in failover | | Centralized Management | No (per-instance config) | Yes (Configuration API / central admin) | | Licensing | Per-instance, per-device tag count | Per-node + enterprise-wide tags | | Best for | Small to mid-size sites | Large-scale, mission-critical operations | Example pricing scenario:
Many engineers assume the standby node sits idle. It does not. The standby node actively polls all PLCs at the same rate as the active node to maintain current values. This doubles the load on your industrial network. If you have 100 PLCs, each polled 10x/sec, the standby node adds another 1000 polls/sec. Ensure your network switches can handle it. Takeaway: Enterprise is roughly 3x the cost of

Result: Manual or "bumpless" failover is not guaranteed.
Some factories use Kepware to aggregate data from 10+ sub-networks (each with its own PLC). If that aggregator goes down, all dashboards, MES, and historians go blank. Enterprise ensures that aggregator is redundant.
