Device for maintaining automation systems for monitoring e.g. control variables, has central data center and external processing units forming virtual central warehouse for replacement equipment and/or spare parts for field devices

摘要

The device has multiple field devices (4) for determining, monitoring and controlling process variables. A central data center (1) comprises networked servers (5) with external processing units (2) connected with different locations, organizations, and/or inventory assigned by requesting and/or offering participants through an Internet site (6).
