Codes
before
register
addresses:
R = Read only
W = Write only
RW = Read and Write
Register addresses are in decimal numerical system.
R1000: Displayed value high 16 bit
R1001: Displayed value low 16 bit
Remark: the displayed value is 32 bit, signed, integer.
This value is without reference to the place of decimal point.
See refer the R1002 register also.
R1002: Number of decimal character (0-4)
Caution !
The displayed value (R1000 and R1001) is valid only when
fault (R1003) is 0.
R1003 (Error):
0 = no error
1 = missing calibration (repearing must be carried out in
service)
2 = input not connected
3 = potentiometer is not calibrated yet
4 = A/D overflow
5 = A/D underflow
6 = scaling error (e.g.: in case of bad scaling)
7 = displayed value < allowed minimum value
8 = displayed value > allowed maximum value
R1004 (Input mode):
0 = temperature measurement
1 = potentiometer position displayed in %
2 = resistance measurement
3 = potentiometer position displayed in scaled form
R1005: (wire mode):
Pt100 / Pt500 / Pt1000 / resistance / potentiometer
connection (2 / 3 / 4 wire)
