Setting up the büS network
Type ME43
Denethedirectionfortransmissionoftheprocessvalues(from/toPLC,from/tobüSdevice):
ThedirectionisassignedfromtheperspectiveoftheeldbusgatewayME43intheeldbusbüS.
Example:
-Theset-pointvaluesofabüSdevicearetheoutputvaluesoftheeldbusgatewayME43.
-TheactualvaluesofabüSdevicearetheinputvaluesoftheeldbusgatewayME43.
ProcessoutputvaluesofthePLCarereceivedbytheeldbusgatewayME43asprocessinputvaluesvia
Industrial Ethernet. These process input values are converted and provided as process output values via
büS.
Conversely, process output values of the büS device are received as büS input values. These process input
values are converted and output as process output values via Industrial Ethernet.

Based on the type of conversion, büS devices can be addressed directly using their process values and the
direction of conversion.
