Description
S1...S16 Alarm2
-101.0…2000.0deg 0.1deg 0.0deg
Sets the value for Alarm 2. The alarm is activated if
the measurement goes above or below this setting
mode (depends on the selected mode in "Sx
Alarm2 >/<").
When the RTDs have been set, the values can be read to SCADA (or some other control system). The
alarms can also be used for direct output control as well as in logics.
Events
The resistance temperature detector function (abbreviated "RTD" in event block names) generates
events and registers from the status changes in ALARM and MEAS INVALID. The user can select
which event messages are stored in the main event buffer: ON, OFF, or both. The function offers
sixteen (16) independent stages; the events are segregated for each stage operation.
The events triggered by the function are recorded with a time stamp and with process data values. The
function registers its operation into the last twelve (12) time-stamped registers.
