SCADALink IP GATEWAY
FOR PIPELINE SCADA COMMUNICATIONS
The SCADALink IP Gateway integrating
Modbus TCP Gateway, Serial Ethernet Gateway, and Modbus Multiplexer
function in a single integrated device is ideal for pipeline
automation systems where multiple masters must communicate to
multiple slave devices.
Pipeline companies can utilize the SCADALink IP Gateway to allow SCADA communications to PLC, RTU's, Flow Computers, and
Gas Analyzers over IP communication networks. Modbus TCP Gateway Slave Mode
The IP Gateway is a Modbus TCP Gateway which enables communications
between Modbus TCP
master devices and Modbus RTU slave devices or between Modbus
RTU master devices and Modbus TCP slave devices (devices can
include: SCADA Host PCs, PLC, RTUs, Gas Analyzers, flowcomputers,
data loggers, VFD's, etc, ...).
Configured in slave mode, the IP Gateway connects directly
to Modbus RTU slave devices to enable communications to remote
Modbus master TCP devices.
Modbus Master Mode
Configured in master mode, an IP Gateway connects directly
to legacy Modbus RTU master devices to enable communications
to remote Modbus TCP slave devices.
Serial Ethernet Gateway
The IP Gateway supports
Modbus TCP, TCP, and UDP protocols in both client and server
modes. The IP Gateway serves as a 3 port Terminal server and
in Virtual Serial mode provides a transparent logical serial
connection over Ethernet and emulates a Nailed-up
serial connection, giving protocol independent operation. In
Slave mode the IP Gateway can allow shared multiplexed access
to a serial port, for Master/Slave request response protocols
such as Modbus.
Multiplexer
The IP Gateway can also functions as a Modbus Multiplexer,
allowing up 2 local Modbus Master serial ports, and 3 IP clients
to share a Modbus Slave port.
Communications
Flexibility
The SCADALink IP
Gateway has timing control features to enable IP communications over a range of media
including satellite, radio, frame relay, ADSL, and fiber connection..
