Fig 40 OPCXMLeditor interface (SIMATIC S7 item classes)
On the left side of the data area, one or more data sets (associated to OPC serv-
ers) are shown in a tree-based structure. For SIMATIC S7, a large set of prede-
fined classes is given. Instead, for generic OPC units, an example of data set
named ‘Example OPC server’ is provided by default.
The command bar includes the following options:
A
Save the last changes on disk files
B
Copy (currently not available)
C
Paste (currently not available)
D
Delete the select object
E
Undo (currently not available)
F
Load an XML file previous saved by OPCXMLeditor
G
Save the selected data set into an XML file
H
Add a new data set of item classes (= a new OPC server): a name and an (op-
tional) server ‘Prog ID’ are required. If no Prog ID is specified, then the data set
is defined as generic and can be applied to any server.
I
Add a new OPC item class, which can then contains command, state and
transaction data
J
Add a command life-cycle data. This is an OPC data for transmitting a com-
mand from MM8000 to the field via the OPC server.
Format type and MM8000 property are required. Supported formats are:
Empty/Default (same format as the state), Short Integer (2 bytes), Integer (4
bytes), Single floating point (4 bytes), Double floating point (8 bytes) Currency,
String. The MM8000 property applied in this item class must be selected in a
drop-down list.
