The real world is where you live and work, and far too often communication products are designed without taking that into consideration.  Liaison communication processors are the result of our own frustration with commercial solutions. Our communications processors are designed from the ground up for the realities we encounter every day in various process industries.

Because perfect information is a fantasy and surprises are unsurprising, Liaison communication processors is ready for those last minute changes and additions.  Units come standard with serial and Ethernet ports with options to add various fieldbus interfaces and the S3 and S5 supports simultaneous utilization of multiple ports using multiple protocols.  Once you've installed a Liaison communication processor, you can simply add data points, channels without having to buy yet another little black box.

Successful communication links are often about more than just communication.  Liaison communication processors are smart--smart enough to know how and when to send or read data, and how and when not to.  Liaison scripted logic provides a whole new dimension to implementing communication links, allowing the insertion of real-time logic to rescale data or to apply permissions or threshold values  to determine when data can be transmitted or queried.  Data can also be time-stamped and archived to internal or external storage (PI servers or similar).  If you can think of it, we can probably do it--right out of the box.

Liaison communication processors feature extensive resources to handle large data point volumes over mutliple, independent communication channels.  Channel redundancy is a standard feature with true primary/secondary switching for serial (where supported by client devices), Ethernet and fieldbus protocols.  How many points?  Thousands.  How many channels?  dozens by experience, hundreds theoretically.  Liaison communication processors are also hot swap redundant.

The Liaison system features deep diagnostics and process data monitoring remotely accessible over Ethernet (or WIFI) using standard internet browsers.  Indications are organized from the general (pseudo-LEDs showing activity and status) to transaction-level error codes, natural language error messages and finally packet-level protocol analyzer capability.  Configuration can also be conducted through the browser.  The S3 and S5 units also have files accessible as Microsoft Windows™ network drives for easy back-up.  All units support FTP (file transfer protocol) and Telnet or SSH.  A TTY connection is also available over a user-selectable serial port.

Any Liaison communication processor can be configured with multiple projects, or configurations.  These projects can be loaded by menu selection to instantly change the character and function of the unit, enabling it to instantly replace any one of several  active units as a pre-validated spare.
