The terminal allows exchange of information by means of a LCD which displays the
values of all controlled parameters, selected set-points, alarm thresholds and in
general all data concerning the controlled variables in the specified formats.
Moreover, the display will show particular messages any time an alarm condition
occurs. A keypad allows the setting of configuration parameters such as set-points,
alarm thresholds, alarm activation delays, etc. ...
