N
Used to input and displays the feedforward value and status.
Range and unit of the FF_SCALE
Note: The feedforward input is multiplied by the gain (FF_GAIN) before it is added to
the calculated output value OUT.
S
Used to input the proportional gain (factor).
1.0
Note: The parameter must be set to a value unequal to 0, otherwise a configuration
error is set in the BLOCK_ERR parameter and the block goes into O/S mode.
D
Grant or deny access of a fieldbus host system to the field device.
Note: This parameter is not evaluated by the Type 3787.
D
Shows the status of the alarm for the high alarm limit (HI_LIM), including details about
the alarm timing (date, time) and the value which triggered the alarm.
Note: The unit of the alarm status parameter is taken on by the PV_SCALE parameter.
Additionally, the active alarm can be manually acknowledged in this parameter group.
D
Shows the status of the alarm for the high high alarm limit (HI_HI_LIM), including
details about the alarm timing (date, time) and the value which triggered the alarm.
Note: The unit of the alarm status parameter is taken on by the PV_SCALE parameter.
Additionally, the active alarm can be manually acknowledged in this parameter group.
S
Input of the alarm limit for the high high alarm (HI_HI_ALM).
If the value PV exceeds this limit, the HI_HI_ALM alarm status parameter is issued.

3402823466 x 10
S
Determines the action to be taken when the high high alarm limit (HI_HI_LIM) is
exceeded.
0
The violation of the high high alarm limit is not evaluated.
1
No message issued when a violation of the high high alarm occurs.
2
Reserved for block alarms.
3...7
The violation of the high high alarm is issued with the corresponding
priority (3= low priority, 7= high priority) to notify the user.
8...15
The violation of the high high alarm is issued with the
corresponding priority (8= low priority,15= high priority) as a critical alarm.
0
S
Input of the alarm limit for the high warning alarm (HI_ALM). If the value PV exceeds
