Serial Port Work
➢
Serial Port Work(Applied to the actual field work mode)
PC port of the host computer connected to the Ethernet port of this series of devices,This series of equipment
serial port and the lower computer PLC serial port connected(RS-232/485/422),Implement the transmission
of TCP to serial link on the Ethernet link.
Mode
Disabled, Tcpclient,
Tcpserver, Udp,
ModbusTCP(RTU_MASTER),
ModbusTCP(RTU_SLAVE),
ModbusTCP(ASCII_MASTER),
ModbusTCP(ASCII_SLAVE),
Default: Disabled
Set the data to the Ethernet switch and transmit the working mode of
the serial port. Tcpclient: In this working mode, the serial port
actively connects the remote IP destination ports. With Tcpserver into
pairs used. Tcpserver: In this working mode, the serial port listens for
the client connection. With Tcpclient into pairs used. The Udp:UDP
protocol does not establish a connection to send and receive data only
to the destination port of the remote IP when transferring using the
UDP protocol.
MODBUS TCP(RTU_MASTER): Master communication mode is
Modbus TCP, asynchronous serial
transmission(RS-422/485),Corresponding communication mode is
MODBUS RTU for slave.
MODBUS TCP(RTU_SLAVE): Asynchronous serial
transmission(RS-422/485),Corresponding communication mode is
MODBUS RTU for master. Slave communication mode is Modbus
TCP.
MODBUS TCP(ASCII_MASTER): Master communication mode is
Modbus TCP, asynchronous serial
transmission(RS-422/485),Corresponding communication mode is
MODBUS ASCII for slave.
MODBUS TCP(ASCII_SLAVE): Asynchronous serial
transmission(RS-422/485),Corresponding communication mode is
MODBUS ASCII for master. Slave communication mode is Modbus
TCP.
Disabled: Close the serial port.
Local Port
Number
1~65534
Set the local port number for this serial port.
RemotePort
Number
1~65534
Set this serial port through Ethernet communication remote device
destination port number.
RemotePort
IP Address
xxx.xxx.xxx.xx
x
Sets the IP address of the remote device that this serial port
communicates via Ethernet.
Bytes Max
Delay
0~999 default:500
Serial to Ethernet data time interval, when the set time interval
is reached, data forwarding, you can set the value of 0-999.
