7.3.1 Sensor Transducer Block
It is necessary to set parameters as shown in
Table 7.2 when the simulation function is used.
When SIMULATE MODE in SENSOR Transducer
block described at Table 7.2 is set to “1: Pressure
Value”, the sensor transducer block uses the
simulation value instead of the pressure value
“SECONDARY_VALUE_1” before carrying out
scaling and linearization.

7.3.2 AI Function Blocks
When the parameters are set in the transducer
block, it is necessary to set parameters as shown in
Table 7.3 in the AI function blocks. When Simulate_
Enabled in AI function blocks described at Table 7.3
is set to “1: Enabled”, the each AI function block that
set this parameter uses the simulation value instead
of the data from the transducer block.
