New functions Applications Customer benefits
Communication of the CPU
Network management pro
tocol SNMP
A simple configuration option is now available
for using SNMP services. For new configura
tions, this is disabled by default in line with
"Security-by-Default".
Simpler configuration
OPC UA server – Reading the
diagnostics status of the own
address space
The own namespace of the OPC UA server can
be accessed by using the OPC UA instruction for
reading ("OPC_UA_ReadList").
This allows you to read out the following status
and react to it in the user program:
• Status of the own OPC UA server
• Status of the connections of OPCUA clients
• Status of the session
• Status of subscriptions
This allows connection problems to be
quickly detected, for example, and plant
availability to be increased.
OPC UA server – Time stamp
ing of the source time of
nodes
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).
Distinction between the "source" and "server"
time possible
OPC UA server – Increased
configuration limits
The following configuration limits have been
increased:
• Possible number of nodes in the server
interface
• Maximum possible number of subscriptions
per session
• For subscription, the recommendation for
monitored values was increased
Further applications for CPUs as OPC UA serv
ers
Web server of the CPU
New Web API methods Many new API methods expand your access
options to the CPU via the Web API.
Additional applications for the Web server
Dynamic management of cer
tificates
The Web server certificate for HTTPS commu
nication can now also be managed via the OPC
UA GDS mechanism, without separate down
load of the hardware configuration.
Flexible certificate management
