PID_Control_DUT

This DUT can be used with the following instruction(s): FP_PID

We recommend specifying the non-hold type area.

Elements of the DUT (identifiers):

w0

Since this is a DUT with overlapping elements, the BOOL members occupy the same data areas as the WORD member w0. Therefore by using w0 you can simultaneously access all bits.

b0_AT_Request

(Bit 0)

When set, auto- tuning is requested. This bit is reset when auto-tuning is complete. Reset this bit to cancel auto-tuning. When not set, PID control will be executed.

b1_AT_Complete

(Bit 1)

When set, auto-tuning has been completed successfully.

b2_HoldMV

(Bit 2)

When set, the manipulated value output is held when the execution condition changes from FALSE to TRUE.

b3_UseAnalogOutputControl

(Bit 3)

• FALSE to use PWM control.

• TRUE to use an analog output unit for output. In this case transmit the output value (F356_Parameters_NonHold_DUT.MV) to WY of an analog output unit.

b4_UseReducedInternalOutputRange

(Bit 4)

• When FALSE, the maximum value of the internal output is the output upper limit value +20% of the output range (output upper limit value - output lower limit value), and the minimum value is the output lower limit value -20% of the output range.

• When TRUE, the maximum value of the internal output is the output upper limit value, and the minimum value is the output lower limit value.
