進(jìn)程范圍指針參數(shù)指向具有范圍縮放的另一個(gè)功能塊，例如模擬提供過(guò)程變量的輸入。這使控制器能夠規(guī)范化過(guò)程輸入的范圍。如果未配置此參數(shù)，控制器將使用0.0-100.0的范圍縮放。
通電-在熱啟動(dòng)期間，輸出和比較器功能將在通電前的狀態(tài)下初始化并且所有動(dòng)態(tài)元素將在第一次掃描時(shí)在當(dāng)前輸入處初始化。在冷啟動(dòng)期間，所有輸出和比較器狀態(tài)將設(shè)置為零，由塊功能激活。所有動(dòng)態(tài)元素將
在第一次掃描時(shí)在當(dāng)前輸入處初始化。ORSL功能塊在每個(gè)循環(huán)一個(gè)的基礎(chǔ)上使用并且它們啟用主輸入信號(hào)，例如輸出以被其它信號(hào)覆蓋。為了選擇器配置為L(zhǎng)O，功能塊輸出
主輸入或超控輸入中的較低者。對(duì)于選擇器配置為HI，功能塊將輸出較高主輸入或超控輸入。超馳信號(hào)可以是：硬限制，來(lái)自等待塊或信號(hào)來(lái)自其他控制器。塊超馳輸入1和2 can用作HI或LO選擇器功能。
附加的通過(guò)連接這些，可以適應(yīng)超馳輸入信號(hào)選擇器（SEL）塊的輸入。
當(dāng)ORSL塊的輸出不是主要輸出時(shí)輸入時(shí)，輸出OS將為高（1）。此外阻塞會(huì)導(dǎo)致操作員面板顯示：

延遲時(shí)間將等于掃描時(shí)間。

輸出RT（剩余時(shí)間）等于接通時(shí)間-ET。

Input E asserted high (1) will enable the block outputs; when low (0) all outputs will be set low (0).
The process range pointer parameter points to another function block that has range scaling, such as the analog
input that is providing the process variable. This enables the controller to normalize the tuning parameters for the
range of the process input. If this parameter is not configured, the controller will use a range scaling of 0.0 - 100.0.
POWER UP - During a warm start, outputs and comparator functions will be initialized at the state prior to power
down and all dynamic elements will be initialized at the current input on the first scan. During a cold start all
outputs and comparator states will be set to zero, to be activated by the block functions. All dynamic elements will
be initialized at the current input on the first scan. ORSL function blocks are used on a one per loop basis
and they enable a primary input signal, such as the output
from a controller, to be overridden by other signals. For a
selector configured as LO, the function block outputs the
lower of the primary or override inputs. For a selector
configured as HI, the function block will output the higher
of the primary or override inputs. Override signals can be
hard limits, coming from HOLD blocks, or signals coming
from other controllers. Block override inputs 1 and 2 can
be used as HI or LO selector functions. Additional
override inputs can be accommodated by connecting these
inputs to signal selector (SEL) blocks.
When the output of the ORSL block is not the primary
input, the output OS will be high (1). In addition, the
block can cause the operator faceplate to display
‘OVERRIDE’ status when a priority level higher than 0, the default, has been selected.
If an override input is not configured the individual selector will output the other input. When no inputs are
configured, the block will output 0.0 and the OS status will be set low (0). OST_ function blocks provide a high (1) output for a
predetermined time, set by ON TIME, when input P goes
high (1). If input P goes low (0), the output will remain
high until the time expires. If input P goes high during the
on time, the elapsed timer will be re-triggered if RETRIG
is set to YES.
With firmware1.30 and higher the ON TIME is adjustable
over the full range of the display which is 0.00000 to
999999. In earlier versions, the minimum time setting
was 0.1. If the delay time is set to less than the scan time
of the station the delay time will equal the scan time.
Output ET (elapsed time) will ramp from 0.0 to the value of ON TIME and remain there until P goes low (0).
Output RT (remaining time) equals ON TIME - ET.
POWER UP - During a warm start, when PU LAST is set to YES, the block will initialize at the input/output states
and elapsed time in effect at the instant power down occurred. A cold start will initialize the input/output states and
elapsed time to 0.
