Use in integrated operation in SIMATIC Manager is not released.
Remote configuration: Addressing via computer names
When you access computers outside a subnet, use the "Simatic Shell" dialog to configure
access to a PC that serves as proxy for distributing your multicast packages.
As "Multicast Proxy", you can also directly enter the computer name, as alternative to the IP
address.
Archiving
Connect or terminate database backup with VBS
For connecting
or disconnecting a database backup, a new example is available in the WinCC
Information System under "VBS for creating procedures and actions > Examples of VBScript
> Examples of WinCC".
This example describes access to a swapped-out WinCC process value archive via the WinCC
OLE DB Provider. A backup file is connected, read and the connection is terminated again.
Compressed archive: Differences for ascending/descending values
As of WinCC V7.4, the differences for ascending and descending values of compression tags
are stored.
The difference is calculated for the ascending and/or descending process values of two
archiving cycles. The overflow of values is taken into consideration when the high or low
counter limit is reached.
New ODK function in alarm logging
As of WinCC V7.4, the advanced function "MSRTGetMsgCSDataExMC" enables access to
the configuration data of messages.
The function always returns the following data:
● Tag names with a server prefix in the "MSG_CSDATA_EX_STRUCT" structure via the
"MSG_CSDATA_CALLBACK_PROC" callback function
● List of message numbers, each with a callback to the given message
"MSRTGetMsgCSDataExMC" replaces the "MSRTGetMsgCSData" and
"MSRTGetMsgCSDataMC" functions.
The new function also supports distributed systems, in which clients with a separate project
are used.
