4 Enter values for each parameter.
Parameter
Description
Display Name Template
Template string used to generate display name of OPC UA variable(s).
Note that 1 or more variables can be created for each record in the
Variables tab.
If more than 1 variable is created, the desired number of variables in
entered in the Number of variables field. Also, the Display Name
Template field must contain a C-style format string to include the index
of the variable, starting from 1.
Example: If the Display Name Template is defined as MyTag_%03d,
and the Number of Variables is set to ‘3’, then the following tags are
produced:
MyTag_001
MyTag_002
MyTag_003
Number of Variables
Number of variables in the group. In the example of above; 3
NodeId
Node ID of variable. This parameter is only applicable if:
Number of Variables = 1
Data Type = ByteString
Once the Variable is created, its NodeId is automatically assigned a
value from 1 to 63992. It is dependent on the starting bit index of the
byte (8 bits) or word (16 bits) that the variable is assigned to within the
PLX32-EIP-MBTCP-UA database.
Example: If a set of three Int16-type variables is assigned to PLX32-
EIP-MBTCP-UA database index 2000, 2001 and 2002, the NodeID =
32001 for the 1st variable, NodeID = 32017 for the 2nd variable, and
NodeID = 32033 for the 3rd variable.
Data Type
Data type of variable
Size
Size of data area used by a single variable in module memory, in bits
Length
Length of variable, in bytes. This parameter is only applicable if:
Data Type = String or ByteString
Offset in Bits
Variable’s position, starting at module memory 0, in bits.
Offset in Bytes
Variable’s position, starting at module memory 0, in bytes.
Offset in 2-byte Words
Variable’s position, starting at module memory 0, in words (2 bytes).
Parent Folder Name
Name of the parent folder, relative to the folder Root/Objects/PLX32-
EIP-MBTCP-UA. If it is empty, the variables are created in this folder.
This parameter is applicable in the UA Client’s Address Space. It
displays the variables that the UA Client is receiving from the UA
Server.
Example: If the Parent Folder Name is “MyInt16TypeTags” and there
are three “Int16Tags_%03d” tags configured, the UA Client displays
the tags in the following manner:
PLX32-EIP-MBTCP-UA
|_ MyInt16TypeTags
|_ Int16Tags_001
|_ Int16Tags_002
|_ Int16Tags_003
