7. Readout of the Actual Counter State by
Serial Communication
At any time you can read out the actual counter state and more values via serial link. For
setting of serial communication parameters etc., you must however apply PC setup anyway, as
shown later.
ZU 252 uses the DRIVECOM communication protocol according to the ISO 1745 standard.
Details about the protocol can be found in our document “SERPRO.doc”, available for download
under
The following register codes are available for readout:
C1 C2 Description
:
8 Actual conversion result, scaled as % of full scale output, format xxx.xxx % *)
;
0 Actual count of input A
;
4 Actual count of input B
;
3 Actual output voltage of the analogue output, scaling 0 – 10 000 millivolts
*) under consideration of the scaling operands as shown in section 10.
