Table 1. Operational Technology terms

Term	Definition
Equipment model	The service records that describe how an industrial operation is organized to produce an output or product.
Production process	The relationships between equipment model entities and the various stages of the workflow from the raw material to finished goods.
Site	A parent equipment model entity record that has no parent. This is a special equipment model entity record because it is used to assign read or write level access to the OT devices assigned to the site.
OT device (site assignment)	The site assignment is needed for role-based security (RBAC) of OT devices. This is implemented as a choice list reference field on the OT Device Details (cmdb_ot_entity) table portion of the OT device record because an OT device can belong to only one site.
OT device (automates::automated)	The automates::automated by relationship describes how the OT device is related to the production process, which could include more than one equipment model entity.
Windows	In both OT and IT networks, the Windows server is represented in the cmdb_ci_win_server server. Additionally, the Windows server in the OT network has a reference in the cmdb_ci_win_server.cmdb_ot_entity field pointing to a record in the cmdb_ot_entity table that describes its function in OT and other OT characteristics like Purdue Level, site, and so on.
