SCADALink SS20 SCADASwitch – Modbus Multiplexer / RS-232 Switch
The SS20 is a datacom interface device for SCADA & industrial control applications where two independent host or master devices need access to a slave device or network of slave devices, and/or to provide communications failure detection of serial networks.
The SCADASwitch SS20 has two RS-232 input ports and one output port that has both RS-232 and RS-485 interfaces. The SS20 also has a USB connection for configuration, Local operator interface to connected devices, and built in protocol analyzer. With low power draw, small size, DIN rail mounting, and Class I Div 2 rating it is ideal for use in remote EFM/RTU applications.
SCADA Host/Modbus Multiplexing Mode
Allows 2 SCADA hosts to simultaneously poll the same network of RTU / EFM devices. The SS20 can perform multiplexing on any request-response protocol including Modbus RTU, ASCII, ROC Protocol, and BSAP Protocol.
Modbus RTU Address Translation
Translates Modbus address on Input Port to a different address on Output Port. This feature is useful when the same RTU exists on 2 different SCADA networks and needs to be addressed with a different Modbus address on each network.
Prevent Modbus Writes to PLC/RTU/EFM on a specific Input Port. This feature can be used to grant Read-Only access to a third-party SCADA host.
Monitor communications traffic through the SS20 and indicate com failure via relay output. This feature can be configured to watch for specific types of messages or specific addresses and has configurable timeout settings and relay output states.
RS232 Radio Keying
Allows an RTU with no handshaking signals to key a radio modem that requires keying.
Converts RS-232 to RS-485.
Simultaneous RS232/RS485 Outputs
Allows flexibility in SCADA Installations where both RS-485 and RS-232 devices need to be interfaced without adding extra converters or serial splitters. Isolated RS-485 Outputs prevent ground loops.
USB Override (LOI) Mode
When the USB Port is connected and the USB mode switch is set to LOI, the USB port overrides the RS232 inputs and routes USB traffic directly to the RS232/RS485 outputs. This mode is used for programming and maintenance access of downstream devices.
USB Data Tap Mode
When the USB Port is connected and the USB mode switch is set to TAP, the USB port can be used to monitor the output port traffic. This mode can be used for data communications troubleshooting.
Custom Industrial Serial Applications
The flexible SS20 platform can be the basis for custom industrial serial applications including:
- Protocol Conversion such as Modbus Protocol interfaces for specialized devices
- Serial Communications Monitoring
The SCADALink SS20 is configured using the SS20 GUI Software connected via the USB port.
