#20101 - 07/15/08 03:48 PM Bobcat RS232 Data Value

I'm reading post #19730, but the only value I'm getting returned from the Bobcat is 65535, even when I send messages from it (which is working). It also doesn't change with any ASCII I transmit to it either. I have tried this with two separate Bobcats, each version 8 with V3.18.

Any ideas what I may be doing wrong? Looking at wrong?

Did you set your termination character correctly? Don't forget that it has to be an exact (and case sensitive) match of both the ASCII string and the termination character. If you set the termination character to ^010 (linefeed) and are looking for string "ABC"; and you actually send "ABC^013^010" (carriage return and linefeed) then it won't work.

The termination character is set to 13, which is the default. Using your example I'm sending "ABC^013". What I find interesting is that even if I use CPUXA to transmit ASCII messages from the Bobcat, I see the correct message come out, but I never see its data value change from 65535 on the Controller Access screen. I also have the following:

IF Module #3 -BOBCAT-A is > -100
THEN Load Data to: Variable #3

Variable #3 is always 65535, even when I send a message. Since the Bobcat value never becomes anything else, I can't use the change to drive anything. It seems like the value should be changing to the message # I send, right?

One thing I've noticed now is that the value changes to 65534 when I transmit to the Bobcat. That tells me it's receiving what I send, however, doesn't find it. I'm not sure why since I've cut and pasted the exact ASCII from the ASCII Messages page.

But why don't I see the value change when I have the Bobcat send a message using CPUXA?

Monitoring the bobcat's value on the controller access screen might not give you chance to see the value for evey program pass, since C-Max samples the values periodically. Try changing you test program to something like this (assuming that the string you want to match is in location #1):


IF Module #3 -BOBCAT-A becomes = 1
THEN Variable #3 + 1


This incement variable #3 by 1 if the bobcat returns a value of 1, even for a very short time.

It never increments that way. I can do:

IF Module #3 -BOBCAT-A becomes < 65000
THEN Variable #3 + 1

and I can see it increment. But if I set it to become any specific number I don't get a change.

Ok, then try capturing it too and tell me what it is (what veriable #4 gets set to):

IF Module #3 -BOBCAT-A becomes < 65000
THEN Load Data to Variable #4
THEN Variable #3 + 1

Variable #4 never changes, but variable #3 increments.

#4 is always zero.

I also have:

IF Module #3 -BOBCAT-A becomes = 0
THEN Variable #5 + 1

and Variable #5 never increments either.

What version are your bobcats? They need to be version 6 to be able to include embedded (formatted) variables, and be version 8 to be able to receive and match ascii data.

Yes, a version 5 will not be able to put out a formatted variable or receive and match incoming ASCII data.

No, unfortunately that cannot be done.

Is it a hardware or firmware problem?

It's not a "problem" as such, but the new features had simply not yet been added to the firmware in the earlier bobcat version.
