Function Blocks
D.1.1 Functionality
Simulation
To support testing, either change the mode of the block to manual and adjust the output value,
or enable simulation through the configuration tool and manually enter a value for the
measurement value and its status. In simulation, the ENABLE jumper must be set on the field
device.
Note
All F
OUNDATION
™
fieldbus instruments have a simulation jumper. As a safety measure, the jumper
has to be reset every time there is a power interruption. This measure is to prevent devices that
went through simulation in the staging process from being installed with simulation enabled.
With simulation enabled, the actual measurement value has no impact on the OUT value or the
status.
Figure D-1. Analog Input Function Block Timing Diagram
37 OUT_D None
Discrete output to indicate a selected alarm
condition.
38 ALM_SEL None
Used to select the process alarm conditions that will
cause the OUT_D parameter to be set.
39 STDDEV
% of OUT
Range
Standard deviation of the measurement for 100
macrocycles.
40 CAP_STDDEV
% of OUT
Range
Capability standard deviation, the best deviation that
can be achieved.
