FAQ / Frequently Asked Questions

Half-duplex transmission of RS-485 is performed on LE-series. Even if it is possible to transmit, it is not possible to receive.

It might be not possible to receive at the time of the simulation, because RS-485 driver is in active condition at all times.

To set "AUTO" to the driver control (DRVCTRL), press "MENU" button and then "1" (INTERFACE).
