New functions

This section contains an overview of the most important new firmware functions of the CPU
compared to the predecessor CPU (V2.9).
New functions of the CPU in firmware version V3.0
New functions

OPC UA server – Reading the
diagnostic status of the own
address space
OPC UA server – Time stamping
of the source time of nodes
OPC UA server – Increase of the
quantity structures
Web server of the CPU
New Web API methods:
Dynamic management of certi­
ficates

Equipment Manual, 11/2022, A5E33591411-AE
Applications
A simple configuration option is available for
using the SNMP services. For new configura­
tions, this is disabled by default in terms of
"Security-by-Default".
By using the OPC UA instruction for reading
("OPC_UA_ReadList"), the own namespace of
the OPC UA Server can be accessed.
This allows you to read out the following
statuses and react to them in the user program:
• Status of the own OPC UA server
• Status of the connections of OPC UA clients
• Status of the session
• Status of subscriptions
By using the OPC UA instruction for writing
("OPC_UA_WriteList") it is possible to change
the "SourceTimestamp" as well as the status
code of an OPC UA variable (node).
The following quantity structures have been
increased:
• Possible number of nodes in the server
interface
• Maximum possible number of subscriptions
per session
• For subscription, the recommendation for
observed values was increased.
Many new API methods extend your access
options to the CPU via the Web API.
The web server certificate for HTTPS communic­
ation can now also be managed via the OPC UA
GDS mechanism, without separate download of
the hardware configuration.
Customer benefits
Can be enabled/disabled in the CPU proper­
ties. Community strings can be configured.
This allows connection problems to be
quickly detected, for example, and plant
availability to be increased.
Distinction between the "source" and "serv­
er" time possible
Further applications for CPUs as OPC UA
servers
Additional applications for the web server
Flexible certificate management
