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 251 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
www.motrona.com
The following register codes are available for readout:
C1 C2 Description
: 8
Actual conversion result, scaled as % of full scale output, format xxx.xxx % *)
: 9
Actual counting result
; 3
Actual output voltage of the analogue output, scaling 0 – 10 000 millivolts
*) under consideration of the scaling operands as shown in section 9.
