Communication Ports on RP-V-5C-M
The RP-V-5C-M model provides the following communication ports:
One RS-485 port with RJ45 interface
One RS-485 port with terminal block
RS-485 Port with RJ45 Interface
The RS-485 port is labeled:
RS-485 Com A
The RS-485 Com A port is rated 3 W (24 VDC).
The RS-485 Com A port is an RJ45 port. Более подробную информацию см. RJ45 Pinout for the RS-485 Port(s) of the RP-V Controllers .
The RS-485 Com A port can be configured to use one of the following two communication protocols for different types of networks:
Sensor bus
Modbus
An RP-V can have only one of each network type.
The sensor bus is designed for communication with SpaceLogic Sensor devices. Более подробную информацию см. RP-V Sensor Bus .
The Modbus (RTU) network can be used for communication with standard Modbus devices. Более подробную информацию см. RP-V Modbus .
Default configuration:
Sensor bus on the RS-485 Com A port
