New functions of the CPU in firmware version V3.0
New functions Applications Customer benefits
Communication of the CPU
Network Management Protocol
SNMP
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".
Can be enabled/disabled in the CPU proper
ties. Community strings can be configured.
OPC UA server – Reading the
diagnostic status of the own
address space
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
This allows connection problems to be
quickly detected, for example, and plant
availability to be increased.
OPC UA server – Time stamping
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 "serv
er" time possible
OPC UA server – Increase of the
quantity structures
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.
Further applications for CPUs as OPC UA
servers
Web server of the CPU
New Web API methods: Many new API methods extend your access
options to the CPU via the Web API.
Additional applications for the web server
Dynamic management of certi
ficates
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.
Flexible certificate management
