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. WebModBus is ontwikkeld voor het verbinden van en communiceren tussen industriële apparaten zoals PLC’s. Omdat de data input van de huidige PLC’s veel groter is dan …
