Example:
Read parameter r52051[2] (temperature power unit 3) from DO 2 (in this case, DCP_CTRL)
Service "Get Attribute single" with the following values:
EtherNet/IP task
Value
Comment
Class code
402 hex
Drive object 2 (default: DCP_CTRL)
Instance ID 52051 Parameter r52051:
temperature sensor power unit display
Instance Attribute
2
Index 2: temperature power unit 3
Example:
Write to p0009 (device commissioning parameter filter) in DO 1 (in this case, CU_DCP)
Service "Set Attribute single" with the following values:
EtherNet/IP task
Value
Comment
Class code 401 hex Drive object 1 (default: CU_DCP)
Instance ID 9 Parameter p0009:
device commissioning parameter filter
Instance Attribute
0
No index
Data
1
Parameter value: [1] device configuration
The data type of the parameter, and therefore the representation in the user data of the
Parameter Object, is specified by the drive and can be found in the SINAMICS DCP List
Manual (Chapter "List of parameters").
Note
For write access, the number of us
er data bytes must correspond to the parameter data
width.
Otherwise, the write request is rejected.
Examples:
•
Precisely 2 bytes must be transferred for a parameter, data type Integer16 (e.g. P0010).
•
Precisely 4 bytes must be transferred for a parameter, data type FloatingPoint32.
