1

Item suffix

The new item ID used for the virtual item that is created by the module consists of the item ID of the source item + the specified suffix. Original item ID and suffix

are separated by a dot. E.g. if suffix is calculated and the source item is NETx\XIO\KNX\IP_Router\01/0/000, the ID of virtual item that is created by the module is NETx\XIO\KNX\IP_Router\01/0/000.calculated.

string

mandatory

2

Base path or base item ID

Specifies the

base path for searching within the item tree when multiple items shall be selected.

string

empty

3

Selector

If multiple items shall be selected, the selector specifies the matching pattern for the items below the base path. The selector itself is a regular expression. E.g. if the base path is NETx\VAR\Numeric and the selector is the regular expression .*Item00.*, the items NETx\VAR\Numeric\Item001 toNETx\VAR\Numeric\Item009 are selected.

string

mandatory

4

Data type

BOOL, STR, BYTE, CHAR, INT8, UINT8, INT16, UINT16, INT32, UINT32, INT64, UINT64, FLOAT, DOUBLE, DATE, TIME

R

5

Access mode

The access rights of the virtual item that is created.  Allowed values are R (read-only), W (write-only), RW (read and writable).

6

Description

The description of the virtual item that is created. If left empty, the description of the source item is used.

7

Persistent

The persistent flag of the virtual item that is created. If left empty, the flag of the source item is used.

empty/true/false

8

Synchronize

value * 10 + 5

.
