Internet PLC Forum

Thanks for the quick reply  Had been battling with that a while, simple fix/work around.

Thanks for the reply. The variables of interest are stored in DM[]. What you are suggesting is one way, I would consider, except, it's not worth more than $20 in software at best. My main thinking was toward the "Run" line has arguments similar to a script that would open the right windows, and connect to the PLC. I haven't looked to see if I could send commands to the PLC, much like communicating with a modem with "AT...".

Oh, though at the moment, it's a Windows computer, it could in future be Ubuntu Linux or similar.

Piece of code from Custfun
 IF " < 10
CTRPV[3] = CTRPV[3] +1
ELSE
CTRPV[3] = 1
ENDIF

In Online monitoring mode:

In the Custfun, select "CTRPV[3]"

Displayed in the lower window:
CTRPV[3]
Current Value (retrieved from PLC) = 0

From the Online monitoring contact value screen
Counter 3 = 1

From, SETLCD 3,20,STR$(CTRPV[3],1)
"1" is displayed on the screen

Recently I had taken advantage of the new feature of defining DM[]'s with names. The program had worked previously, and general runs OK, but appears to be acting as if CTRPV[3] = 0

Any thoughts. I see the new feature where I can use a name in the CTR argument and probably will convert that to names in the future after I get this working.

Good work! I had only 2 Label names that ended in "R", and only one of those was at the end of an active line, but numerous times. Adding the " " to the end of the line cured the situation. The other variable never was at the end of an active line, but "r" did occur numerous times at the end of comment lines and were not an issue.

There are numerous contact (input, relay, etc.) names ending in "R" (and including "r") that have not been a problem.

The 16 character limit is OK, I had only 1 name that was 16 characters, all the others were less.

I do still have numerous contact and label names that do have an underscore "_" not at first or last position that have not been a problem, is there any reason to remove the "_" from those instances? It would be nice if a few other characters were allowable.

Thanks for the quick reply, slowly the picture is evolving. One big question at this time, are my label names too long?? What is allowable length and characters. I have replaced many, there are near 80 DM[]'s in the program, and the majority have now names. Before I go further, need to know to not waste time.

The comment at the end of the line is very interesting. The DM[4000] only appears in one Custfun, but numerous times. I could send the entire Custfun if would help, or even the whole program. This application was started 7 or so years ago, and has occasional additions and modifications over the years. It's just recently that I have worked at cleaning up the code and changing mainly DM[]'s to names for readability. There are many contact and Custfun names with underlines in them. Hasn't been a problem yet, but something to keep in mind with future revisions.

A little more info:
Opened file in Firefox, didn't see anything in the problem area that looked strange. Closed without saving.

Apparently it's more a display problem then an editing issue. I can select the item DM[4000], and paste the replacement "ScreenNumOld". Display loses editing line, and numerous blank line appear below after several untouched lines. Hit the "ESC" key, exiting CustFun. Reopen the Custfun, the editing is complete and displayed properly. Trying to edit other instances of the DM[4000] results in the same issue. DM[4000] is the last (or very near) instance of any DM[] that has not been replaced with a label name. But no problem editing anything else in the Custfun. Both DM[4000] and "ScreenNumOld" are in the define table, and the label is accepted, orange color.

Here is troublesome code that appears 8 times in the custfun:

IF ScreenNumOld <> ScreenNumber
ScreenNumOld = ScreenNumber
SETLCD 0,1,CHR$(1)
ENDIF

If I put the cursor at the end of the second line and hit "DEL", the line disappears and  the empty lines below appear. Then if hitting "Enter", every thing goes back to before"Del".

Had been doing considerable editing of a large (113KB) file, changing DM[] to variable names after importing a DM table, and was going well. The file did recently compile, and load to the PLC with no errors and apparently running correctly.

Did a find all of"DM[" to locate last remnants to change, found first of several instances, adjusted the selected string, and started typing a new string. The entire line including cursor disappeared, and numerous empty lines below. Problem seems isolated to one custfun possibly.  Opened file on 2nd computer running XP Pro Sp3 with same results.

Reloaded Trilogi on Windows 8 with no change.  

At the moment I'm assuming the file is damaged, how can I repair it?

Still looking for some guidance on what the variable name allowances and restrictions are: Length, forbidden characters.
