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

#CMT# #/CMT# 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). The external processing units have information about inventory of spare equipment. The central data center and the external processing units form a virtual central warehouse for a replacement equipment and/or spare parts for the field devices. #CMT#USE : #/CMT# Device for maintaining automation systems for monitoring and controlling control variables. #CMT#ADVANTAGE : #/CMT# The device minimizes cost for storing and retrieving the replacement equipment and/or the spare parts for the field devices, provides a firewall that protects the server and/or the networked servers from intrusion by authorized external processing units and avoids provision of the field devices and/or the spare parts, thus minimizing cost of the device. The device accelerates the access to the replacement equipment and the spare parts, and can easily procure the field equipment and the spare parts that are not produced and reuse the replacement equipment and the spare parts. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a device for maintaining automation systems. 1 : Central data center 2 : External processing units 4 : Field devices 5 : Networked servers 6 : Internet site.
