Hallo zusammen,
ich vermute das wurde schon mal behandelt, ich finde gerade nur nicht die richtigen Suchbegriffe.

Worum gehts: Ich empfange über meinen Modbus-Adapter aus meiner Wago Steuerung ein Word, in diesem sind halt 16 Bits also Booleans die ich gerne aufsplitten würde. Wonach müsste ich jetzt suchen um mich dort ein zu lesen?

gruss Markus

Danke für den Hinweis,
ich habe mir jetzt einen passenden Flow bei Node-Red angelegt. Habe den aber nicht selber erfunden sondern nur auf meine Bedürfnisse angepasst.

Im Modbus-Adapter habe ich dann Unsigned 16bit (Little Endian) verwendet. In der Wago SPS schreibe ich auf ein %MW.

Falls mal jemand diese Informationen brauchen sollte.
