Delta HMI DOPA indirect register Example


1.Human Machine
Interface indirect register
$ arithmetic application.

2. Overview:
Delta Terminal Panel DOP HMI offer 65536 indicator registers $ for user application.When HMI direct connect to AC Motor Drive or AC Servo Drive or
Temperature Controller without through Programmable Logic Controller. We can
utilize HMI’s Marco instruction to performed various mathematics operation, Do
this can simplify programming and less procedure for debugging. On
Temperature-Controller, DTB can collected maximum 64 heating curve and times most,
Following example we utilize HMI indirect register
$ to finish the adding of
all the times.
3. Configuration:
Utilize the Macro function of HMI, reveal after adding the sum
total of a lot of registers of DTB Temperature Controller.

4. Application benefit:
Basic addition way:

Register 1—-> Register 2—>  Register 3—> Register 4—> Register 5—> Register 6

Normally,
While adding above 6 register, must write 6 lines of addition orders add up
them separately, but if want summation is much large, then the procedure will
be very huge, and will waste much programming time.
Using the addition way of $:
When the way to use $ for get
the total amount, so long as cooperate with For —Next instruction.No matter add the total number of number of times, only need to
change the number of times that For close loop and can achieve the goal of calculating, so will
shorten the editor on the procedure greatly.

Required hardware and software components
 Hardware
                              Software
Delta HMI      DOP- A(AE)  series              Screen Editor
Delta
TC          DTB,DTC series       
           DTCOM_E
 
6. Connect
Diagram:
HMI
hardware has built-in RS485 communication interface.
Connect
Temperature Controller RS485 to HMI 9 PIN D-SUB like below. Read more detail from the HMI and TC manual.
7. Principle of
instruction
Down load the HMI
software,
1. Connect to the
Temperature Controller. And get the register values from the Temperature Controller (TC).
2. Or use the off
line simulation to implement the calculation.
3. When set value to
the register from 1 to 24, Screen show like below.
·        
 Addend column: Indicate how
many register already in addition,
·        
 Sum column: the register of
addition.
·        
 Display column: The total
amount of register.
8. Program:
Following Macro’s
instruction get summed up to calculate, finish with 8 lines of procedures altogether.
1.Choose
BMOV to create duplicate 24 registers for calculate procedure. Utilize register
$100 to $123 block
as the buffer.
2.Make
register $500 to 0 before the sum total process.
3.Appointed
Indirect register $200 as 100 (Determine from register $100 begins).
4.Set
FOR- NEXT times, so 24 times of circulation.
5.Add
the indirect register.
6.Add
the next register.
7.NEXT
(cooperate with FOR to enclose using).
8.Will add the total
final result while reaching $501 in order to be shown in HMI picture.
 
9. Other:
a. Temperature Controller must use DTB or DTC series.
b. HMI software ScreenEdit version must 1.05.74 or above.
c. Another example:
1. Originally we have been doing the calculation that is summed up
to these 24 register all the time, while only needing to accomplish the 15th step on the customer’s
use, it sets 0 to the 16th
register then, procedure will add, reduce to 15th stop
automatically.
2. In real using, we must calculate the 16th to bring this value
into the execution step of the warm
accusing of device after 0, could let the control of the warm
accusing of device operate step 15
actually too (will not still operate 24 sections), But because
there is no use which uses the indirect register *$ in the operation type in the middle, so this
component will not be listed in proving.
3. Below program show when check the indirect register value is 0,
Then calculation procedure
stop. Only
add the front registers which not equal to zero.
Operate
the picture:
1.When
set value to the register from 1 to 24, Screen show like below.
2.
Zero register No. column: Indicate the zero value register number. Fro example
13th
3.Sum
column: the 1 to 12 register of addition.
Display column: The
total amount of register.
1.
Choose BMOV to create duplicate 24 registers for
block
as the buffer. calculate procedure. Utilize
register
$100 to $123
2.
Set $150 =1 (show that begins to judge from the first
register)
3.
$200 =100, Show the content of *$200 equals the
content
of $100.
4.
Utilize FOR to enclose judging whether this register is
0.
5.
If 0, leave, go back, enclose. Present $150 content
shows
promptly this position is 0.
6.
If not 0, add $200 by 1, in order to judge the next
materials.
7.
$150 adds by 1, i.e. add the position that will judge
next
time by 1.
8.
NEXT (cooperate with FOR to enclose)
9.
LABEL1 (cooperate with IF judging type of 5th line)

FOR at this moment goes back to enclose the summation,
it is 24 that it is fixed that not, but the parameter
$150 (the position of 0) .
