6.4 Manufacturer specific objects
The definition of the following objects is manufacturer specific. They are used to set the CANopen strain link.
List of supported objects:
Object Name
2000 Averaging time
2001 Store autozero
2002 IIR filter cut-off frequency
2003 Autozero
2004 Status autozero
2100 Baud rate
2101 Identification
2112 Transmit data type 16/24bit
6.4.1 Averaging time
The average time specifies the time in ms over which the measured values are arithmetically averaged. The
average time can be set between 0..1000 (0..3E8h).
The sensor internal averaging contains a 32bit buffer. If an averaging time >32ms is selected, just every 2
nd
measurement is used. With averaging time >64ms just every 3
rd
value is used, and so on.
If the IIR-filter is enabled, the averaging should be disabled and vice versa.
Read averaging time (object 2000h):
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
600h + ID 8 40h 00h 20h 00h 0 0 0 0
Response from CANopen strain link:
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
580h + ID 8 4Bh 00h 20h 00h 1Eh 00h 0 0
Byte 5 + 6:
1E’00h 00’1Eh (LSB first) 30ms (Default value)
Change of averaging time:
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
600h + ID 8 22h 00h 20h 00h 64h 00h 0 0
Byte 5 + 6:
64’00h 00’64h (LSB first) 100ms
Response from CANopen strain link:
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
580h + ID 8 60h 00h 20h 00h 0 0 0 0
