! object.
! - Do1 will be set as long as S0 is active. The SetDo function implies latching
! and the Do1-signal remains set even when S0 becomes inactive. The Do1's SetDo
! is not included in any order list.
! - Since StoDo for Do2 is not included in any order list it will execute each
! time when the PLC program executes. Do2 gets status according to the step
! - Do0 will be set when S0 becomes active. Because Ord1 has an S-order attribute
! it will remain set even when S0 becomes inactive. Do0 is not cleared before
! the ORD1 object is reset by a Reset_SO object; cf. Do2.
! - Dv1 and Dv4 are not set at once when the step S0 becomes active. The Ord0
! object is supplied with D and C attributes. In the beginning there is a delay,
! the duration is specified by the Attribute Editor, and then a condition Dv3
! follows. If S0 is active, the delay has elapsed, and the condition is satisfied
! Dv1 is set. Since the Set-function has latching the Dv-signal remains set also
! when S0 becomes inactive. When the delay has elapsed the Dv4-signal follows the
! condition Dv3 as long as the step is active.
! - The thick vertical line in Ord4 indicates that the order has an underlying
! sub-window, in this case a conditional window . If Ord4 is active, the condition
! is satisfied, and DI1 is not set Dv2 will be set, otherwise Dv2 is cleared. And0
! is not in the object's order list. A conditional window is opened in the following
! way: Specify in the object a C-attribute by means of the Attribute Editor. The
! conditional window is opened from the PLC Editor by Shift/MB1 and double clicking
! in the left part of the Order object.
! - Figure See Step and Order with Activity Window shows a part of a sequential chain.
! ORD0 indicates an activity window, and this is shown to the right.

! Step and Order with Activity Window
!
! Suppose that the PLC program executes by the frequency 10 Hz and the signals
! Av1=Av2=0. ORD1 sees that the active status of the step lasts for 5 seconds. Which
! value did Av1 and Av2 get then? The order list begins to execute as soon as the
! step becomes active. Av1 will be increased and stored 20 times when the status of
! Ord0 is FALSE and then 30 times when the status of Ord0 is TRUE. Since the step
! becomes inactive the order list is executed one another time with the order status
! FALSE. This means that Av1 = 51. Av2 is stored only when order status is TRUE,
! which makes Av2 = 30.
!
! To make use of the delay in a D-order either an OrderAct object as in the case with
! ORD0 or the status of the order as with ORD1 is used. Also remember that: as long
! as the step is active the order list will execute independent of the order status .

! MANUAL The MANUAL mode is thought to be handled from the object\s display.
!
! * A set point value is set in SetPos.
! * The positioning is started by setting PosOn to TRUE.
! * The positioning is finished of different reasons:
! @image orm_en1-174.gif

! - the process value has been within the dead-zone intervals,

!
! - PosOn becomes FALSE.
!
! - (the input signal) Reset becomes TRUE.
!
!
! The positioning starts on a leading edge on the input signal AutoPos.
! It can be finished of different reasons:
! - TimerTime > 0. The process value has been within the dead zone
! intervals, i.e. the target range, during a time specified by TimerTime.
! A new positioning process is triggered by a leading edge on AutoPos,
! i.e. not because PosVal is outside the target range.
!
! - TimerTime = 0. The positioning is never finished but continues to
! follow SetPos until Reset becomes TRUE.
!
! - (the input signal) Reset becomes TRUE.
!
! Example
!
! Position Controlled Carriage.
!
! By means of a push button the positioning starts, and the carriage runs
! to a set point value set by a potentiometer. The positioning is to be
! interrupted after 5 seconds in the 'target' range.
