Applications
With STEP 7 and WinCC as of Version
V17, SIMATIC S7-1500 CPUs and ET
200 CPUs from firmware version 2.9
support innovated and standardized
secure PG/PC and HMI communica-
tion – referred to as Secure PG/HMI
communication for short.
You have the option of assigning a
password for protecting confidential
configuration data of the respective
CPU. This refers to data such as pri-
vate keys that are required for the
proper functioning of certificate-
based protocols.
OPC UA clients from any manufactur-
er can subscribe to alarms of the CPU
via OPC UA Alarms & Conditions.
Via GDS push management func-
tions:
• Automated update of OPC UA
certificates of an S7-1500 CPU
• Transfer of updated certificates
and lists in RUN operating state of
the CPU
Customer benefits
Secure and standardized crea-
tion or assignment of PLC
communication certificates
Additional password protec-
tion of confidential configura-
tion data
Without further measures,
alarms created once via OPC
UA are available as events and
alarms. The alarms can be
displayed by any display de-
vice with corresponding OPC
UA client functionality.
The automation of the certifi-
cate management eliminates
any manual work required for
reconfiguring the CPU, for
example, after a certificate has
expired, and a new download
to the CPU.
