HLBL question
Hi list i built an HLBL source where are defined some user labels for Real Output with a name like OUT1 OUT2 and so on. I've also an array (in a subroutine) with a S12 internal flag used to build the same name of the ones used for RO. I made this because i need to reset to zero a certain real output when a given integer and boolean are passed to the sequence. So the structure af the array is sorg[1] := "OUT1" ; sorg[2] := "OUT2" ; .(sorg --> S12) I call the subroutine at first step of the sequence and some steps after i've the IF clause wich test the status of a given boolean and use the array with a given integer . I supposed to do sorg[integer_input] := 0; but nothing run. It's probably because my array build a STRING which can't have a real value ??? If so how can i build the name of a given real output user label and then put it to a given real value ??? (OK probably is the worst way to have this function but when i started i didn't know where i'll arrive...) Thank's lot --- This list is neither sponsored nor endorsed by the Foxboro Company.

Re: HLBL question
Stefano, What you are really doing is converting an integer value (0) to a string (sorg[n]). If it is posible, you can use external references, something like STRING :CMPND:BLK:PARAM'IO0001' := 0.0; I don't have a system alive to test that, I used a similar structure but I can't remember the exact sintax.

RE: HLBL question
How is this example? It will look better if you put it in a file and use a
courier (monospace) font.
Watch how I use APPNAME.
* I declare it (APP_NAME : SN0001;) to be the contents of SN0001
* I use it to get the value of a variable (CTLINT :=
:'APP_NAME':DMCOP.CTLINT;)
Now, look at CNTDWN
* I declare it (CNTDWN : SN0009;)
* I initialize it to the name of the countdown timer (CNTDWN :=
APP_NAME,":DMCOP.CNTDWN";)
* I set the value to 0 (:'CNTDWN' := 0; )
Does this help?

Subject:HLBL question
Hi list
i built an HLBL source where are defined some user labels for Real
Output with a name like OUT1 OUT2 and so on.
I've also an array (in a subroutine) with a S12 internal flag used
to
build the same name of the ones used for RO.
I made this because i need to reset to zero a certain real output
when a
given integer and boolean are passed to the sequence.
So the structure af the array is
sorg[1] := "OUT1" ; sorg[2] := "OUT2" ; .(sorg --> S12)
I call the subroutine at first step of the sequence and some steps
after
i've the IF clause wich test the status of a given boolean and use
the
array with a given integer .
I supposed to do
sorg[integer_input] := 0;
but nothing run.
It's probably because my array build a STRING which can't have a
real
value ???
If so how can i build the name of a given real output user label and
then put it to a given real value ???
(OK probably is the worst way to have this function but when i
started i
didn't know where i'll arrive...)
Thank's lot

RE: HLBL question
If I understand you correct, you want to set one or more Real-outputs on the sequence block to 0? Unfortunately, in HLBL you cant make a variable variable. So you cant build a string which happens to match a variable you declared and then use it in a statement. However, you CAN build variable external references in a sequence to write to its own block. The catch is, you can only do this using input parameters. (cant set RO000x from "outside") So instead of using RO0001 to RO0012, use RI0001 to RI0012, then: Let's assume the number of the RI you want to set is on II0001, and block_name and number are Strings: block_name := BLOCK_NAME; number := II0001; ::'block_name'.RI000'number' := 0; If the number > 9, you must redirect the program (like below) If you want to set all 12 (initialisation or something) then you could: FOR number := 1 TO 9 DO ::'block_name'.RI000'number' :=0; ENFOR FOR number := 10 TO 12 DO ::'block_name'.RI00'number' := 0; ENDFOR If you insist on using the RO, ignore this suggestion. A general warning applies here: Be "critical" using external references (:C:B.P) in sequences, as they could noticeably increase network load when used unwise. An external reference to a compound not in the same CP causes a broadcast. Not a problem, unless you have hundreds of them at the same time. So avoid cunstructions like 'WAIT UNTIL :COMPOUND:BLOCK.PARAMETER" since it will do a broadcast each BPC. Having a bunch of sequences doing this in a bunch of different CP's to a bunch of other CP's at the same time can cause eh... "unessecary" network traffic. (this doesn't apply to above example since we stay in the same CP) Hope this helps, Bram Marsman. -Original Message- From: Stefano Persico [mailto:[EMAIL PROTECTED]] Sent: woensdag 29 augustus 2001 0:09 To: Foxboro DCS Mail List Subject: HLBL question Hi list i built an HLBL source where are defined some user labels for Real Output with a name like OUT1 OUT2 and so on.

Ah, almost right this first time, It should ofcourse be: FOR i := 1 TO 9 DO number := i; ::'block_name'.RI000'number' :=0; ENFOR FOR i := 10 TO 12 DO number := i; ::'block_name'.RI00'number' := 0; ENDFOR where 'i' is declared as interger and 'number' as string. -Original Message- From: Marsman, Bram [mailto:[EMAIL PROTECTED]] Sent: woensdag 29 augustus 2001 10:10 To: 'Foxboro DCS Mail List' Subject: RE: HLBL question If I understand you correct, you want to set one or more Real-outputs on the sequence block to 0?
