PKV3500 Modbus to DH-485

The PKV3500-MB-DH-485 is a Modbus master/slave interface for computers, MMIs, and OEM based applications that require access to a node on AB's DH485 network. Highlights include palm-size portability, DC power, external Din Rail cabinet with Modbus USB or serial functionality to DH-485. The Modbus/DH-485 can be set to be either a Master or a Slave on the Modbus serial link, as well as communicate using either RTU or ASCII protocols. The Modbus/DH485 in Master Mode can read from and write to registers and coils in any Modbus Slave device connected. Slave Mode allows a Modbus Master device to read from or write to files in a A-B PLC or SLC connected to the DH485 network.
