Modbus chip
WebThat's because the RS485 interface is outputting an idle condition i.e. B is the inverse of A because the transmitter is enabled. When idle, the lines A and B from the slave are both HIGH. This is because the slave is set to receive data and the RS485 chip has no control on the lines . External pull-ups are the likely cause of this. WebOn the signal ground, it is best practice to use the wire shield of the Modbus cable between devices, and then add another wire to connect the shield to an earth ground. Only connect the shield wire to earth ground at one end, otherwise you can create ground loops. Do not do it in the middle of the wire run, and don’t do it at both ends.
