OUT_SCALE
LOW_CUT
OUT
SIMULATE
XD_SCALE
CHANNEL
L_TYPE
Shows output value and status. When the Block mode is Man and O/S, the value is held.
Sets the range, unit, and digit of the output scale.
Used for simulation. It sets the value and status arbitrarily from the transducer. Use this parameter for loop
checking. Refer to 7.3 Simulation Function
When the output value is smaller than the value set by this parameter, the output value is 0. To enable the low-cut
function, this parameter must be enabled in IO_OPTS.
Sets the range of inputs from the transducer block that corresponds to 0% and 100% in the AI function block. Also
sets the unit of the range, inputs values that correspond to 0% and 100%, and four decimal values.
Selects the signal which is calculated in SENSOR Transducer Block. The relation between the signals and
channels are shown below;
Channel 1: PRIMARY VALUE (differential pressure)
Channel 2: SECONDARY VALUE (H-side static pressure)
Channel 3: TERTIARY VALUE (L-side static pressure)
Channel 4: EXT_TEMP_VALUE(external temperature)
Channel 5: FLOW_VALUE(flow)
Channel 6: CAP_TEMP_VAL (capsule temperature)
Channel 7: AMP_TEMP_VAL (amplifier temperature)
Flow value(channel 5) can be assigned to only one AI block at one time.
Other variables can be assigned to one or more AI blocks simultaneously.
The operation function of the AI function block can be selected from Direct, Indirect Linear, or Indirect SQRT:
Direct
: The Signal from the transducer block is directly output by filtering only, but without scaling or
square root extraction.
Indirect Linear : Values scaled according to the range settings of XD_SCALE and OUT_SCALE are output.
Indirect SQRT : Values are scaled according to the range settings of XD_SCALE and OUT_SCALE, and then
square root extraction is performed for them before being output.
