Profibus-Dp Set-Up Using Non-Cyclic Data - Control Techniques Profibus-DP User Manual

TELEGRAM 4
The fourth telegram from the master has the stamp number set to 4.
The data bits contain the data low byte for the parameter that is being
written to.
Bit
Value
Data word = 0x04B0
When the fourth telegram has been received and processed in the
slave node, it will write the data (#1.21 = 1200) as transmitted, ignoring
the decimal point. If the operation is successful, the ERR bit is reset to
0 and the telegram is reflected in the non-cyclic IN word.
Bit
Value
Data word = 0x04B0
If there was a problem with writing the data to the defined parameter,
e.g. parameter is read only, does not exist, or data is out of range, the
ERR bit is set to 1.
Bit
Value
Data word = 0x4400

Profibus-DP Set-up using Non-Cyclic Data

The Unidrive Profibus-DP interface can also be configured via the non-
cyclic data channel. Menu 20 in the Unidrive contains the parameter
values currently being used, and these can be modified as required.
Cyclic data mapping parameters can be edited via the non-cyclic data,
but changes made to the data mapping will not take effect until the
UD70 has been reset.
Setting #17.19 to 1 will store the mapping changes in the Profibus-DP
interface, and reset the Profibus-DP interface. The Profibus-DP master
controller may detect an brief error while the Unidrive Profibus-DP
interface resets and re-configures itself.
The parameters listed below are the parameters that can be written to
configure the Profibus-DP interface.
