11. Appendices

This chapter has five parts: a glossary, a command format reference, the optional cluster failover feature, the supported-device list and the per-interface support tables:

• 11.1. Glossary: definitions and calculation methods for concepts such as Machine OEE Data, Group OEE Data and Group Part Count.
• 11.2. Command Format: the format of commands such as PLC Data Task, Precondition, Task Interval, Post-processing ($DA$ / $POST$ / $MOCK$), External PLC Data Task, External Machines, Protected API and Authorized APIs.
• 11.3. Cluster Failover (Optional): how the shared standby pool works, how to build it, failover and switch-back behaviour, forced takeover, and what is not replicated.
• 11.4. Supported Devices: the device types, systems and models the gateway can connect to.
• 11.5. Interface Support: which interfaces and which fields each system and model supports, for HTTP, MQTT RPC and task collection alike.

Enabling, authenticating and configuring clients for the gateway’s built-in MCP server is covered in 9. MCP Service.
