Home > Products > Liaison S3

Low-power consumption, cool-running and compact, the Liaison S3 is nonetheless a full-featured Liaison communication processor with all the functionality of its larger sibling the S5 although fewer possible hardware resources.

The S3 is available in a wide variety of physical port formats starting with the standard two serial ports (RS-232, RS-232 or RS-485) and autoswitching 10/100 Ethernet with RJ-45 port.  S3s can be ordered with as many as 18 serial ports (RS-232 or RS-485), dual Ethernet ports and various fieldbus and proprietary interfaces (i.e Allen-Bradley Data Highway Plus)

Multiple independent channels are supported with your choice of protocols.

Sophisticated communication related behaviors can also be programmed to provide control over how, what and where data is sent. Remarkably all this power is easy to use and requires nothing more than the applications you already have on your computer.

Reliability is built-in with surge, overload, and reverse polarity protection (channel interfaces may provide isolation or isolation options).  Every channel is watchdogged independently of all others, allowing automatic recovery from transient conditions.  The S3 is also standard with channel redundancy and hot-swap capability.

Diagnostics, process data monitoring and configuration are remotely accessible over a LAN.  Software functions are accessible through common Internet browsers.  Diagnostics are designed to scale from the general to the specific, with pseudo-LEDs to indicate activity, status as if you were viewing a panel device.  Numerical status codes are associated with each mapping (query or update transaction).  Natural language logs for error, boot, monitor, system and debug logs.  The debug logs feature protocol analyzer function.  Logs can be viewed within the browser or downloaded as text files through Windows™ Explorer

Processor data can be viewed by data type or by tag name.

Liaison communication processors feature a project paradigm that lets each unit store as many projects as necessary or desirable.  Modifications or additions to the configuration

• Configuration, File Transfer, Monitoring and Diagnostics use standard MS Windows applications like MS Excel, Wordpad, Windows Explorer and Internet Explorer. No special configuration software is required

• Available in a variety of hardware configurations from an Ethernet port and two RS-232 serial ports up to 10 serial ports (RS-232 or RS-485). May include a selection of fieldbus interfaces (AB DH+, DeviceNet, Profibus DP, etc...)

• Simultaneous support for multiple protocols permitting a choice of protocol support for the end-user and interoperability between system components.

• Multi-level recoverability from communication errors (watchdogging) by channel.

• -Extensive logging, including error, trace, system, and authorization logs

• Scripting provides complete control over data flow, type conversion, scaling, etc...

• Extensive support for remote and secure monitoring, diagnostics and administration using encrypted internet protocols and access permissions. FTP, Telnet, HTTPS, SSH

• Low power consumption, Compact size, DIN rail mount, high electrical isolation

• Windows Explorer drag & drop file exchange, web-browser monitoring & diagnostics, spreadsheet (Excel) configuration (no specialized software required)
