15 Reserved

14 Array

13 Parameter value can be reset only

12 Parameter has been changed from

factory setting

11 Reserved

10 Additional text array available

9 Parameter is read-only

8 Standardizaton factor and variable

attribute not relevant

0-7 Data type

Number of Array Elements

Contains the number of array elements, if the parameter is an array; the string length, if the

parameter value is a string; or 0 if the parameter is neither.

Standardization Factor

Conversion factor for scaling a given parameter value to standard SI units.

For example, if the given value is in mV, the standardization factor will be 1000, which converts

the given value to V.

The standardization factor is in Float format.

Variable Attribute

Consists of 2 bytes. The first byte contains the variable index, which defines the physical unit of

the parameter (e.g. Ampere, Volt).

The second byte is the conversion index, which is a scaling factor for the parameter. In general

all parameters accessible by PROFIBUS are organized and transmitted as real numbers. The con-

version index defines a factor for conversion the actual value to a standard physical unit. (a

conversion index of -1 means, that the actual value must be divided by 10 to become a standard

physical unit e.g.. Volt.

Name

Contains the parameter name, limited to 16 characters, e.g. “LANGUAGE” for parameter 1. This

text is available in the language selected in par 1.

Lower Limit

Contains the minimum value of the parameter. Format is 32 bit signed.

Upper Limit

Contains the maximum value of the parameter. Format is 32 bit signed.
