jump to StEP5.
StEP5
:
C05=160 , t05=0
The program get in Hold state, and run operation executed by operator is
needed for the program to continue running to StEP 6.
StEP6
:
C06=100 , t06=-151
Alarm 1 is switch off, and jump to StEP1 to start from beginning.
In this example, it is assumed that the positive deviation alarm is set to 5
℃
. Because the temperature of
StEP 6 is 160
℃
, and the temperature of StEP1 is 100
℃
, when program jumps from StEP 6 to StEP 1, the
program will change to preparation state at first, i.e., Control the temperature until the deviation between
setpoint and PV is less than positive deviation alarm value. After temperature is controlled to 105
℃
, the
program will be started from StEP 1, and run the above steps again. The temperature control block is shown
below.
7.2.1 Time setup
txx = 1—9999 (min)
setting time of No. xx StEP
txx = 0
the program is hold on StEP xx
txx = -1—-30
negative value of time represents an operation command such as: run, Hold, stoP, jump
and even output, the signification is as follows:
txx=-121
Program is stopped.
Note:
The program will be held if it jump from a control segment to another control segment (an Hold
action will be inserted between two control sections), external run/Hold operation is needed to
release the Hold status. It is not allowed that the jump section jump to itself (for example: t 06= -6),
otherwise, the Hold status can not be released.
