6.4 Measuring Point Designation
Each measuring point can be given a 10-digit alphanumeric designation to
optimally identify the type of sensor, the measuring location or the purpose of
the application. This designation appears in the 1st line of the display before
the measured value:
Meas.Point Designation
´
Temperature´
0001:Temperature
In case of outputs via interface the measuring point designation appears in the
program header as ´
COMMENT
´ and in the list of measured values (man. 6.6.1).
The input is performed within the function MEAS.VALUE with using the key
ENTER
according to 5.5.
6.5 Limit Values, Hysteresis
Two limit values (Max, Min) can be programmed for a measuring channel. The
exceeding of the limit values is, as the exceeding of the measuring range limits
and sensor breakage, handled as disturbance (see manual 6.3.9) and the
corresponding red control lamps will be on. The control lamps of MAX.VALUE
and MIN.VALUE still indicate the disturbance, even if it has disappeared
already. Disturbed measuring channels will be provided as output via the
interface during a measuring point scan within a measuring cycle. An
exceeding can also be used to start or stop a measuring point scan (s. 7.3.6).
Any disturbances only disappear after the measured value has dropped below
the limit value by the hysteresis. The hysteresis is, at every new initialisation,
set to 10 digits. However, it can, within the function
Hysteresis
, be commonly
set for all channels from 00 to 99.
