Internet PLC Forum

I am setting up a test rig to cycle a switch and want to display it's number of cycles in the millions, however, the values I display are limited.  Is there anyway to display numbers in the millions or greater?

I am currently using the 7” touch screen MMI6070H with a Triangle Research PLC FMD1616-10, however, Easybuilder8000 says does not support device type.  I looked through the setup as well and the PLC is not listed.  
I have used the smaller screen MMI6050 in the past without any issues, however, I needed to download a driver.  
Are there any drivers for the MMI6070H I would need to have it work for the Triangle Research PLC FMD1616-10?  

My sequence is advanced by each cutom function via an IF THEN ELSE statement (shown below).  Each completion of a test sets the CTRPV to the next sequence for the next test, hence, I cannot use a clock pulse for advancement.  However, I am not sure how I could use a timer though?

IF TESTBIT (INPUT[1],1) THEN
   IF INPUT[1]+INPUT[2]+INPUT[3]+INPUT[4]+INPUT[5] & &HFFFD THEN    'CHECK IF ANY OTHER INPUT #1 TO #16) IS ON
      CALL 2:
      SETLCD 2,1,D$+"A3 &"      
      CALL 8:
   ELSE
      IF CTRPV[1]=1 THEN
         CTRPV[1]=2
         SETLCD 0,0,CHR$(1)
      ELSE
         CTRPV[3]=10
         SETLCD 0,0,CHR$(1)
      ENDIF
   ENDIF
ENDIF

Close yes.  The PLC is a part of a diagnostic tool I've designed.  
The diagnostic tool is attached to a piece of equipment that requires testing. When the user sees an error occur, they fix the equipment.  When fix is complete, the PLC sees the error disappear and the program continues.  The next test does not occur until the current fault is eliminated.  When all the tests within the program pass, that indicates the equipment is good.

My issue is during the testing, the error messages are displayed for a brief moment, so a successful test, which takes a couple minutes, cycles through error messages every split second until it says "Test successful".  The program is able to perform the task well, but the display is not ideal for the end user.

That would work if all of my tests were happening at the same time, however, each of my 50+ tests happen in sequence and displays an error for a brief moment until it understands it is not an error and skips to the next test in the sequence.  

So calling a function every 5 seconds would only create a delay for this case.  However, this is useful for future programs on other applications for me.

The following is typical code for my custom functions.  I've also attached a *.jpg of the ladder logic, but I am not sure if it will show up....

'A3 OPEN TEST
IF TESTIO(A3_CS)=0 & CTRPV[1]=1 THEN
   CALL 1:
   SETLCD 2,1,B$+"A3" 'Line 2, Column 1
ELSE
   IF TESTBIT (INPUT[1],1) THEN
      SETLCD 0,0,CHR$(1)
   ENDIF
ENDIF
'SOCKET 33 TO A3 - NCS CONNECTOR TO NCS OPEN TEST
IF TESTIO (A3_CS)=0 & CTRPV[3]=9 THEN
   CALL 1:
   SETLCD 2,1,E$+D$+"A3"+G$+"2-A" ' LINE 2, COLUMN 1
ENDIF
'SHORT TEST
IF TESTBIT (INPUT[1],1) THEN
   IF INPUT[1]+INPUT[2]+INPUT[3]+INPUT[4]+INPUT[5] & &HFFFD THEN    'CHECK IF ANY OTHER INPUT #1 TO #16) IS ON
      CALL 2:
      SETLCD 2,1,D$+"A3 &"      
      CALL 8:
   ELSE
      IF CTRPV[1]=1 THEN
         CTRPV[1]=2
         SETLCD 0,0,CHR$(1)
      ELSE
         CTRPV[3]=10
         SETLCD 0,0,CHR$(1)
      ENDIF
   ENDIF
ENDIF

How do I perfrom a delay in the ladder logic?  

I have about 50 custom functions all which call up different variations of error messages if certain conditions are not met, so I would have to place the "delay" on each rung?  If so, what is the delay function?

I have a program that performs a large amount of tests in sequence and displays error messages and pauses the sequence until the error is cleared.

The problem is as the test runs, it displays each error for a short period of time which is something I do not want the user to see as they are not actually errors, they are just the program running.  I would like it to display something like "Testing..." until it has an error for more that 3 seconds which would indicate an actual error found.  Does anyone know how to approach this?  Or is there a function that can do this?
