Siemens Desigo SX Open - SX Configurator, V2.1 CM110702en_06

Building Technologies Worksheets in SX Configurator 20 Mar 2012

Column Description

Item Set Ref

Reference to an Item Set from the sheet of the same name.

Can be used for this

type of import.

Device Set Ref

Reference to a Device Set from the sheet of the same name.

Not used for this

type of import.

Depending on the number of items, the number of changes-of-value per unit of

time and the use of the values on the BACnet side, it is therefore advisable to

select update rates that are as long as possible, to avoid unnecessarily impairing

the performance of SX Open. If several groups are to be formed with the same

update rate, the update rates entered must vary by milliseconds, e.g. 1000ms,

1001ms, 1002ms, etc.

For OPC items which are VT_ARRAYS, each element of an array (matrix) uses one

row in the Configuration sheet.

SX Open supports only a fixed number of elements per VT_ARRAY.

For data imported from the OPC source, only the first row of the VT_ARRAY is

displayed. If other elements of the array are to be mapped, copy the row and

modify the array index and BACnet object name and keyname accordingly.
