      Goodbye to everyone .. I finally finally managed to recognize the 1-Wire basic temperature sensor of the PLC .. it works properly ..
      But now I need a help ..
      I also bought two sensors of the UNICA Wire Sensor (temperature-humidity and light sensor) all in one.
      The problem is how to connect it .. I have two photos to let you know better.
      Virtually I connected to terminal 5 i + 5V, to 6 the DATA, 7 empty, 8 GND.
      I connected it to the Wire port I tried to make the recognition but with a negative result .. I also attach the screen of how I inserted the device in the Mervis..HO performed the same procedure for the 1-Wire sensor ..2_1504170021892_3.JPG 1_1504170021892_2.JPG 0_1504170021891_1.JPG

        @TriathletC Please check the pin map of the RJ45: https://www.unipi.technology/hardware_documentation/1-wire-network-46

        The wiring seems OK, but you have to wire at also both data lines to the sensor, or you break the topology.

        Also, do not strip the end of cables when you make the RJ45 connector. The connector cuts the plastic foil of the cable when you press it with the crimping tool. If you strip the cables before, the cables can touch each other which could cause shortcut....

                    @TriathletC Try to use FUPLA block called 'unica_u1wt'.

                        Yes, that it should work.
