Setting up of OPC UA server
3.1 Prerequisites
NOTICE
Protection against security risks
To protect industrial plants and systems comprehensively against cyber attacks, measures
must be applied simultaneously at all levels (from the operational level up to the field level,
from access control to copy protection). Therefore, before setting up of the OPC UA server,
apply the "Defense in Depth" protection concept in order to avoid security risks in your
environment.
Ensure that you do not connect the company network to the internet without suitable protective
measures.
You will find further information on the Defense-in-Depth concept, suitable protective
measures and Industrial Security in general in the Configuration Manual Industrial Security
(https://support.industry.siemens.com/cs/de/en/view/108862708).
Requirement
● OPC UA requires SINUMERIK Operate.
● OPC UA requires an OPC UA license (6FC5800-0AP67-0YBO).
● Make sure that the HMI time is set correctly, since this is a prerequisite for encrypted
communication.
