4.11 Integration of single parameters
The following diagram applies to both the additional network variables of standard RXC
applications and to the network variables of third-party applications.
The term “single parameter integration” refers to the mapping of an individual NV
element to the Event Main Value (EVM) of a link point (AI or AO) without any special
additional function.
The diagram below shows the principle of this mapping process.

(The term “LON device” refers to both RXC and third-party device.)
An input (nvi) of the NIDES.RX is mapped to the EMV of an AI point.
An output (nvo) of the NIDES.RX is mapped to the EMV of an AO point.
The link point address consists of two parts: Group address'Element address
The group address of the link point is Device number x.
The Element address of the link point identifies the input (nvi) or output (nvo) on the
NIDES.RX side. The allocation of inputs/outputs to the element addresses is fixed, and
documented in Tables 4.10.1 and 4.10.2.
The NIDES.RX input nviStatus (Object Status) is mapped to parameter ERSTA for all
VISONIK points that belong to the LON device concerned (cf. Mapping rule in Section .
The Object Status must be integrated explicitly for each third-party device.
