(SIMULATE of AI/DI block)
Set the physical device (PD) tag and block tags. Up to 32 alphanumeric characters can
be set for each of these tags. Refer to Section 5.4, “Setting of Tags and Addresses.”
Sets the range of input from the transducer block corresponding to the 0% and 100%
points in operation within the AI function block. The maximum oxygen concentration scale
value shown on an order sheet (WS 1F6A0-01E) is the factory default setting.
Set four data: the unit of the range, the input value at the 0% point, the input value at the
100% point, and the decimal point position.
Set the scale of output corresponding to the 0% and 100% points in operation within the
AI function block. It is possible to set a unit and scale that differ from the measurement
range.
Set four data: the unit of the scale, the output value at the 0% point (i.e., the lower output
scale limit), the output value at the 100% point (i.e., the upper output scale limit), and the
decimal point position.
Select the calculation function of each AI function block from the following:
• Direct:
The output of the transducer block is directly output only via filtering
without scaling and square root extraction (in the range set in
XD_SCALE).
• Indirect: Proportional scaling is applied to the input to the AI function block, and the
result is output (in the range set in OUT_SCALE).
• IndirectSQRT: Square root extraction is applied to the input to the AI function block and
the result is output (in the range set in OUT_SCALE). This setting is not
used for a AV550G.
Simulation of each AI/DI block can be performed in such a way that the value and status
of the input to the block can be set arbitrarily. Use this function for loop checks or the like.
Refer to Section 6.3, “Simulation Function. ”
