Object Formatting
This manual will display the Object and Entry data using the model detailed below.
Object Description
Index | Name | Object Code | Data Type |
XXXXh | Index Name | VAR | I/U |
Index
The Index is the hexadecimal number that represents the index number of the object in the CANopen Object Dictionary. With the exception of IMS Manufacturer specific objects these are defined in CiA Device Profile for Drives and Controls DSP402. The applicable objects are defined in this document as well.
Index Name
The Index Name is the general name and description of the object. With the exception of IMS Manufacturer spe- cific objects these are defined in CiA Device Profile for Drives and Controls DSP402.
Object Code
VAR - Variable
Data Type
Physically, the types consist of one or more bytes. One byte consists of 8 bits (Bit 0 to 7). Bit 0 is the LSB (Least Significant Bit). A byte can also be depicted hexadecimally (0x00 ... 0xff).
If a data type consists of n byte, the following applies:
Data byte 1 (Byte in address x) = highest value byte
Data byte n (Byte in address
The data coding and the value ranges for the respective data types apply, unless otherwise explicitly stated in the data description of an MDrivePlus communication object.
