Internet PLC Forum

Ok figured it out.  Once I reached output 40 in the program, the hardware skips the next 16 bits, so I can't use outputs 41 to 56, however, output 57 and up do work!  I guess the first 16 bits are reserved for a PLC's I/O even though the expansion is connected to another expansion?  

I wonder what happens to a PLC with less or more than 16?

At least I have it working with my program now  

I've tried a blank program and forcing outputs,  both expansions work.

I've tried a very simple program that turns on an output, both expansions work.

In my main program, the first expansion operational, but the second expansion still does not function.  I've even placed a line of code that simply turns on an output to the second board, and still nothing turns on, although the online monitioring screen shows the output as being on.  Really scratching my head on this one  

That's a neat little trick, unfortunately,  I inserted the code as
CALL 1, CALL 2, etc.... to save additional space and the trick doesn't work unless I use the name.

I have a very large program, however, there are a lot of areas that have repeat commands such as:

SETLCD 0,0, CHR$(1)
SETLCD 1,1,A$

Is there anyway to put the entire "SETLCD...." into a string?

Or any other tips for space saving would be appreciated.

I've been having troubles with setting up a sequencer.  
I have the basic arrangement in the ladder logic, however, I want the sequence to change each time one of the CusFn of each rung completes and I am unsure what code I can place in there to make this happen.  I tried a SetIO xxxx, CLRIOxxxx at the end of the code, but it doesn't seem to be working.  All I need is some bit to go from on to off to trigger the AVseq.  Any help would be appreciated.  

I've noticed that even when input #3 is on and inputs 1# to #16 are off, the message...

  SETLCD 0,0, CHR$(1)
  SETLCD 1,1,"SHORT CIRCUIT BETWEEN"
  SETLCD 2,1,"PIN A3 &"

...still remains, should it not disappear?

Thank you, it sort of works, but there is still an issue.  My code looks like this:

IF TESTBIT (INPUT[1],2) THEN
 IF INPUT[1] & HFFFE THEN
  SETLCD 0,0, CHR$(1)
  SETLCD 1,1,"SHORT CIRCUIT BETWEEN"
  SETLCD 2,1,"PIN A3 &"
  CALL 8:
  DELAY 1000
ENDIF
END IF

CALL 8 LOOKS LIKE THIS....

IF TESTIO(A1_CS)=1 THEN
 SETLCD 3,1,"PIN A1"
 DELAY1000
ENDIF
IF TESTIO(A5_CS)=1 THEN
 SETLCD 3,1,"PIN A5"
 DELAY1000
ENDIF
IF TESTIO(A7_CS)=1 THEN
 SETLCD 3,1,"PIN A7"
etc......

The problem now is the messages only appear if the first A5_CS occurs.  If the other inputs are ON, they cycle, which is fine, however, if A5_CS is gone, the rest will not display their message.

I am using a T100MD1616+ and a MMI6050 and have run into a few issues with my project.

I want to monitior and compare inputs.  For example, if input 1 is on and any other input or combination of inputs turns on, I want to be able to distinguish this and output an error message.  Is there a command line to compare and monitor all the inputs?  
TESTIO (1-20) something like that.
