Why is a Liaison communication processor a better choice than a protocol converter or other specialized device?
First, communication links are often necessarily the last element considered in any project and it is the unexpected considerations that make the flexibility and power of the Liaison communication processors a valuable tool. Liaison technology was created in response to our experience in commission on-site links. The economic considerations of a communication link extend well past the capital equipment expenditure. Commissioning time, time required for troubleshooting and support all have significant value, usually far more than the rather minor expenditure for the equipment. Liaison communication processors provide extensive diagnostic and monitoring capabilities, many of which are usually only found in high-end RTUs (including remote monitoring, diagnostics and configuration). Secondly, Liaison communication processors provide a wider range of options for dealing with unforeseen and unknown elements of a communication link. User-defined functions can produce programmatical behaviors
