12. Open Analog Input function block 1.
13. Set the operating mode in the MODE_BLK parameter group (TARGET parameter) to
OOS, i.e. the block is out of service.
14. Use the parameter to select the process variable which should be used as the input
value for the function block algorithm (scaling and limit value monitoring functions).
The following settings are possible: CHANNEL → Uninitialized Primary Value 1
Primary Value 2 Sensor Value 1 Sensor Value 2 Device temperature
15. In the XD_SCALE parameter group, select the desired unit and the block input range
for the process variable concerned.
Incorrect configuration
Please ensure that the selected engineering unit suits the measured variable of the
selected process variable. Otherwise, the BLOCK_ERROR parameter will display the
"Block Configuration Error" error message and the operating mode of the block cannot
be set to AUTO.
16. In the L_TYPE parameter, select the type of linearization for the input variable
(direct, indirect, indirect sq. root), see Section 13.
Please note that if the "Direct" linearization type is selected, the settings in the
OUT_SCALE parameter group are not taken into account. The engineering units
selected in the XD_SCALE parameter group are decisive.
17. Define the limit values for alarms and warnings using the following parameters: –
HI_HI_LIM → limit value for the high alarm – HI_LIM → limit value for the high
warning – LO_LIM → limit value for the low warning – LO_LO_LIM → limit value for
the low alarm The limit values entered must be within the value range defined in the
OUT_SCALE parameter group.
18. In addition to the actual limit values, the behavior in the event of limit value
overshoot must be specified by "alarm priorities" (HI_HI_PRI, HI_PRI, LO_PR,
LO_LO_PRI parameters), see Section 11. Reporting to the fieldbus host system only
occurs if the alarm priority is greater than 2. In addition to the settings for the alarm
priorities, digital outputs can be defined for limit value monitoring. These outputs
(HIHI_ALM_OUT_D, HI_ALM_OUT_D, LOLO_ALM_OUT_D, LO_ALM_OUT_D
parameters) then switch from 0 to 1 when the specific limit value is exceeded. The
general alarm output (ALM_OUT_D parameter) in which different alarms can be
grouped must be configured appropriately via the ALM_OUT_D_MODE parameter.
The behavior of the output in the event of an error must be configured in the
parameter Fail Safe Type (FSAFE_TYPE) and if FSAFE_TYPE = "Fail Safe Value" is
selected, the value to be output must be defined in the parameter Fail Safe Value
(FSAFE_VALUE).
