The inputs of theKL3022 are differential inputs which share a common earth.

5 As aresult theKL3022 is ideally suited to measuring earth free current loops. A voltagedifference at the inputs, due cross voltages, of up to 35 V result in anegligible inconsentency in the measured value of the formatof process dataIn the default setting, process data is represented in the twos complement(-1 corresponds to 0xFFFF). By way of the feature register, other modes ofrepresentation can be selected ( amount representation,Siemens output format).Measured valueDecimal outputHexadecimal output4mA00x000012mA163830x3 FFF20mA327670x7 FFFLED displayThe four RUN LEDs indicate the operating state of the affiliated LEDs: RUN:On normal opeationOff a watchdog-timer overflow has occurred.

The Terminal s data ismapped differently in the bus coupler s memory depending on the type ofthe bus coupler and on the set mapping configuration ( / Intelformat, word alignment,..). For parametrization of a Terminal , the control/status byte must also be LightbusCoupler BK2000In the case of the TRS Lightbus coupler BK2000, the control /status byte isalways mapped besides the data bytes.
