Relationship between ”Wire break” and measuring range
If the ”wire break” parameter is deactivated in the configuration software and the
measuring range
1.1 mA, then ”8000
H
” is output and bit 6 ”measuring range
underflow” is set in byte 21 of the station diagnosis.
If the ”wire break” parameter is activated and the measuring range
3.6 mA, then
”8000
H
” is output and bit 4 ”wire break” is set in byte 21 of the station diagnosis.
