Hello,
I've to connect a cFP2020 controller with a temperature controller via RS485 in 2-wire mode (tcontrollers interface- must be 2-wire). The datatransfer is done (if RS485 works ;-)))) by MODBUS protocol using RTU mode (cFP-master, CAL9400-slave). To initialize the serial port (Com4 cFP), I shortened the adequate lines on the RJ-45 connector and tried to initialize the port in LabView RT 7.1, using the Property Node Function to switch to the 2wire/Auto tranceiver mode (write). Now if I tried to run this initialization, I always got an error at property node 😞
Has anyone an idea to avoid this error message ?
