11 OPC UA Server
The OPC UA Server can be installed as an optional software package (see
"Software Units"). This chapter describes the use of the OPC UA Server on
Weidmüller controls with the Linux operating system.
OPC Unified Architecture (OPC UA) is a standard for manufacturer-indepen-
dent networking of devices in the automation sector. This provides standard-
ized access options to the control. This standard allows any program (e.g.
an OPC UA client) that supports this standard to communicate with the Wei-
dmüller control and access data. For general information see: www.opcfoun-
dation.org
Overview
The OPC UA Server runs in addition to the applications on the control and
allows OPC UA clients to connect.
