Data records

4.2.2.1

Data records 100 and 101

The data records are written to Slot 0. The number of the data record determines the relevant target device.
For this:

DS 100  Access to the technology unit (parameter range 150…199)

DS 101  Access to the frequency inverter (parameter range 0 … 999, except 150…199)

NOTE

The inverter parameters are mapped in the range 1000 to 1999, i.e. 1000 must be added to the
parameter number for parameterisation (e.g. (P508) - P1508).

Explanation

Parameter number

and

Order label

2 Bytes

FI or SK TU3 parameter

The parameter number is a 16 Bit value (+1000) and can be obtained from
the relevant operating manual for the frequency inverter or technology unit.

The order label is added to the parameter number. (upper Nibble)

Parameter index

2 Bytes

Parameter sub-index (see Section 4.2.3.2)

Parameter value

4 Bytes

New setting value (See Section 4.2.3.3).

4.2.2.2

Data record 47

This data record is written to Slot 0 and is then assigned to the relevant device on the basis of the axis. The
format is compliant withe the ProfiDrive profile.

Field

Data size

Explanation

Order reference

1 Byte

The order reference is transferred from the IO controller and is used for the
definitive allocation of the SK TU3-PNT response

Order label

1 Byte

Read / write parameter value etc. (see Section 4.2.3 )

Axis

1 Byte

Access to SK TU3-PNT parameter or FI parameter

0 = SK TU3-PNT

1 = Frequency inverter

Parameter number

2 Bytes

FI or SK TU3 parameter

The parameter number is a 16 Bit value (+1000) and can be obtained from
the relevant operating manual for the frequency inverter or technology unit.

Parameter index

4.2.2.3

Transfer of data record via PPO 1 and PPO 2

PPO1 and PPO2 objects are supported in order to simplify the conversion of an existing PROFIBUS system
to a PROFINET system. In addition to the cyclical IO data, there are also the acyclical parameter data (see
Section 4.2.4.4).
