Machine PLC Symbols

PLC symbols

This page is generated from the Unity twin. Published from _docs/context/plc-symbols.md — edit it there, not here. Changes made in the wiki are overwritten on the next sync.

Every device that is a real PLC symbol: it carries oc.deviceType and neither oc.aggregatedBy nor oc.simulationDevice. 87 of them.

Devices excluded by that test are listed under their group's own page, so nobody generates a symbol for a panel button or a simulation-only device.

† From the reference scene only. Every scene instances the same Machine_1 prefab, but each adds its own vendor's operator panel, so this row is VC_Demo_1_Beckhoff_1's and another scene spells it differently. The machine is what is unmarked; a marked row is an example. Each vendor's own is on its page below.

Per device type

The interface a device type presents - its control function block, its process-image members and its bit layout - is on the type's own page, not repeated on every instance.
