TELEMETRY
Every Alliance RTO is equipped with a Programmable Logic Controller
(PLC)
equipped with a serial port that is attached to a purpose built paging modem.
The paging modem allows monitoring of the ladder logic as is
done with a conventional modem and the paging modem will
automatically
call and deliver detailed text messages to the mobile phones of our
service and engineering personnel to alert them immediately
in the case of any upset condition or warning.
The paging modem allows us to know of a problem instantly and
directly so that we can prepare a quick solution.
With the paging modem in place we are able to provide
extended hour support for the maximum uptime of the system.
In addition to the paging feature,
The
PLC performs both control of the RTO and data logging. Every
event, warning and fault is time and date stamped and stored in the
PLC memory. Key process variables are recorded at regular
intervals and stacked into the PLC memory.
