6.3.6 Status of measurement
Read status of measurement (object 6150h):
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
600h + ID 8 40h 50h 61h 01h 0 0 0 0
Response from CANopen strain link:
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
580h + ID 8 4Fh 50h 61h 01h 00h 0 0 0
Byte 5:
00h actual measurement
03h overflow of AD – converter
05h underflow of AD – converter
The object 6150h is read only.
6.3.7 Process value 16bit
Read process value 16bit (object 7130h):
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
600h + ID 8 40h 30h 71h 01h 0 0 0 0
Response from CANopen strain link:
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
580h + ID 8 4Bh 30h 71h 01h 2Ch 01h 0 0
Byte 5 + 6:
2C’01h 01’2C (LSB first) 300
300 / 10
Number decimal digits
(6132) + unit(6131) = 3.00 µ
ε
The process value is quoted as 16-bit Integer double complement.
The object 2112h is changing the process value from 16bit (object 7130h) to 24bit (object 8130h) and vice
versa.
Example of negative strain:
ID DLC Byte1 Byte2 Byte3 Byte4 Byte5 Byte6 Byte7 Byte8
580h + ID 8 4Bh 30h 71h 01h D4h FEh 0 0
Byte 5 + 6:
D4’FEh FE’D4 (LSB first) -300
-300 / 10
Number decimal digits
(6132) + unit(6131) = -3.00 µ
ε
The object 7130h is read only.
