If required, use the following parameters to define the limit values for alarm and warning
messages:
– HI_HI_LIM -> Limit value for the upper alarm
– HI_LIM -> Limit value for the upper warning
– LO_LIM -> Limit value for the lower warning
– LO_LO_LIM -> Limit value for the lower alarm
The limit values entered must be within the value range specified in the parameter group
OUT_SCALE.
8.
In addition to the limit values you must also specify the action taken if a limit value is exceeded
using the alarm priorities (parameters HI_HI_PRI, HI_PRI, LO_PRI, LO_LO_PRI). Reporting
to the the fieldbus host system only takes place if the alarm priority is higher than 2.

Connection of the function blocks
1.
A concluding overall system configuration is essential so that the operating mode of the Analog
Input Block can be set to AUTO and so that the field device is integrated into the system
application. To do this, a configuration software (e.g. you host system software) is used to
connect the function blocks - normally graphically - to the desired control strategy and then
the sequence of the individual process control functions is specified.

Download the configuration data into the field devices by the download function of the
FOUNDATION Fieldbus configuration tool.

Set the oerating mode of the AI Block to AUTO (parameter group MODE_BLK, parameter
TARGET). However, this is only possible under the following conditions:
– The function blocks are correctly connected with each other.
– The parametrization of the AI Block is correct (
