輸入H將保持當(dāng)前步驟的剩余時間，并通過操作5和禁用定序器的推進(jìn)但將允許操作1、2、3和4將定序器移動到新步驟的開始位置。當(dāng)最后一個定序器步驟完成時，SC將設(shè)置為高（1）。序列器不能移過最后一個
步驟，除非復(fù)位輸入R變高（1），迫使其移動到位置1。只有在位置1時，定序器才能向前移動。網(wǎng)絡(luò)通信將允許定序器移動到新的步驟和剩余時間
將當(dāng)前步長的值更改為新值。當(dāng)使用離散組且需要一個步驟為“僅定時”時，應(yīng)使用一個離散輸入以防止將定序器移動到下一步的輸入掩碼。這可以通過要求高（1）輸入和則不連接該輸入，因為未連接的輸入將被視為0。如果使用離散組，并且希望某個步驟為“僅事件”，則該步驟的時間參數(shù)應(yīng)設(shè)置為0.0。模擬輸出將保持在上一步驟的AEP值，或者，如果在步驟1，模擬值將為0.0。當(dāng)定序器前進(jìn)到下一步時，模擬輸出將轉(zhuǎn)到已完成的AEP值步
通電-在熱啟動期間
，如果PU LAST設(shè)置為“是”，則所有輸出、步數(shù)、軌跡變量和剩余步進(jìn)時間將在斷電前的最后值初始化。冷啟動期間，所有輸出均為：初始化為0，并且PRSEQ處于復(fù)位狀態(tài)。QHD_功能塊允許更改實際值在線使用快速設(shè)置功能。街區(qū)是由將在中顯示的8字符名稱標(biāo)識快速設(shè)置模式。該塊配置有以最小比例和最大比例輸入的范圍，以設(shè)置可用范圍，小數(shù)點位置參數(shù)可以
設(shè)置允許的精度。保持值不能為超出這些限制的-10%至110%值并且將隨著脈沖發(fā)生器的轉(zhuǎn)動而連續(xù)變化。這個最大值必須始終設(shè)置為大于最小值。也可以通過斷言強(qiáng)制塊跟蹤輸入TV輸入TC高（1）。固件1.30添加了參數(shù)QSCHANGE。它使要在中連續(xù)更新的塊輸出快速設(shè)置模式：當(dāng)脈沖發(fā)生器旋鈕旋轉(zhuǎn)或僅旋轉(zhuǎn)至使用數(shù)字顯示中的值更新輸出當(dāng)按下存儲按鈕時。
配置DPP（小數(shù)點位置）時，將分辨率保持在所需的最小值很重要
用于操作更改。如果分辨率太高，操作員轉(zhuǎn)動脈沖發(fā)生器的時間會更長。例如如果只需要0.1%的更改，則將0-100范圍配置為0.0–100.0，而不是0.000–100.000。在熱啟動或熱啟動期間，QHD將在冷啟動期間的最后位置以-10%范圍值通電。比率功能塊可用于每個循環(huán)基礎(chǔ)。它們提供了一種在中設(shè)置比率的方法外部設(shè)定點應(yīng)用，在保持比例的同時控制俘獲流在野生流和圈養(yǎng)流之間期望值。輸入A和E（外部比率）以及運算符集比率R值相乘并變?yōu)椋汗δ軌K輸出O1。
Input H will hold the remaining time of the current step and disable advancing of the sequencer by operations 5 and
6 but will allow operations 1, 2, 3, and 4 to move the sequencer to the starting position of a new step.
When the last sequencer step is completed, SC will be set high (1). The sequencer cannot be moved past the last
step unless the reset input R goes high (1) forcing it to position 1. The sequencer can be moved forward only when in position 1. Network communications will allow the sequencer to be moved to a new step and the remaining time
of the current step to be changed to a new value.
When discrete groups are used and a step is desired as ‘timed only’, one discrete input should be used to prevent the
input mask from moving the sequencer to the next step. This can be accomplished by requiring a high (1) input and
then not connecting that input, since unconnected inputs will be treated as 0.
When discrete groups are used and a step is desired as ‘event only’, the TIMe parameter for the step should be set to
0.0. The Analog Output will remain at the AEP value of the previous step or, if at step 1, the Analog value will be
0.0. When the sequencer advances to the next step, the Analog Output will go to the AEP value for the completed
step.
POWER UP - During a warm start, if PU LAST is set to YES, all outputs, step number, track variable, and
remaining step time will be initialized at the last values prior to power fail. During a cold start all outputs are
initialized to 0 and the PRSEQ is in a reset condition. QHD_ function blocks enable a real value to be changed
on-line using the QUICKSET feature. The block is
identified by an 8-character name that will be displayed in
the QUICKSET mode. The block is configured with a
range entered as MIN SCALE and MAX SCALE to set a
usable range, and a Decimal Point Position parameter can
set the allowed precision. The hold value can not be
changed beyond the -10% to 110% value of these limits
and will change continuously as the pulser is turned. The
MAX value must always be set greater than the MIN value.
The block can also be forced to track input TV by asserting
input TC high (1). Firmware 1.30 added parameter QSCHANGE. It enables
the block output to either update continuously in the
Quickset mode as the pulser knob is turned or to only
update the output with the value in the numeric display
when the STORE button is pressed.
When configuring the DPP (Decimal Point Position) it is important to keep the resolution to the minimum necessary
for operation changes. It will take the operator longer turning the pulser if the resolution is too high. For example,
if only 0.1% changes are needed configure a 0-100 range as 0.0 – 100.0 and not 0.000 – 100.000.
During Hot or Warm start, the QHD will power-up in the last position during a Cold start at the -10% range value. RATIO function blocks can be used on a one per
loop basis. They provide a means of setting a ratio in
an external setpoint application, for example,
controlling a captive flow while maintaining the ratio
between a wild flow and the captive flow at the
desired value. Inputs A and E (external ratio) and the
operator set ratio R value are multiplied and become
the function block output O1.
