Write to a bit of array in plc

[ms ns]

Hi,

I have an array as CommFromPalletizer (DINT[5]). The CommFromPalletizer[0].3 is the load complete signal. When this turns on the completedLoad tag array should be read. Then I would set the CommToPalletizer[0].1 this is the acknowledge signal.

The [0] is the first double integer word in the “CommFromPalletizer” tag array and .3 is the 4th bit in this word. But whenever i try to write the tag I am getting the error code of -4. Please let me know how I can solve this problem.

[Kyle]

Hi, thanks for using the library and bringing this up! 

To make sure, are you writing the entire array or just bit 1?  Are there any protections enabled in the PLC on this tag?  Are you setting this up as two bit tags?  One to read the load complete signal and one to write the ack signal?  What is the exact tag string you use for reading ?  What is the exact tag string you use for writing?

Can you run a write test with debugging output on (level 4) and capture the output?   I.e.

tag_rw -t bit -p 'protocol=ab-eip&gateway=....&elem_count=1&name=CommFromPalletizer[0].1' -w 1 -d 4 &> log

(this is for Linux/macOS, you will need to modify it for Windows)

This will help me understand what error you are getting and where that error is occurring.

Best,

Kyle

Hi Kyle, I have two tags CompletedLoad and CommFromPalletizer. I have succesfully read the CompletedLoad tag. But now I have to read and write CommFromPalletizer[0].3  tag array and .3 is the 4th bit in this word. 

Please find the attached screenshot.

 

Now when I have successfully read the CompletedLoad tag then I have to write to the CommFromPalletizer[0].3 to "1" . The CommFromPalletizer[0].3 is the load complete signal. When this turns on the completedLoad tag array should be read. Then you would set the CommToPalletizer[0].1 this is the acknowledge signal that I have read the completedLoad tag array. 

This is my code to write

tag = new Tag("192.168.1.99", "1,0", CpuType.LGX, "CommFromPalletizer[0]:3", DataType.DINT, 1);

                client.AddTag(tag);

                while (client.GetStatus(tag) == Libplctag.PLCTAG_STATUS_PENDING)

                {

                    Thread.Sleep(100);

                }

                if (client.GetStatus(tag) != Libplctag.PLCTAG_STATUS_OK)

                {

                    Console.WriteLine($"Error setting up '{tag.Name}' internal state. Error {client.DecodeError(client.GetStatus(tag))}\n");

                    return;

                }

                /* TAG_STATUS_WORD */

                var statusVal = client.GetUint32Value(tag, 0);

                if (statusVal == 0)

                    statusVal = 1;

                else

                    statusVal = statusVal * 2;

                Console.WriteLine($"setting 'STATUS_WORD' = {statusVal}\n");

                client.SetUint32Value(tag, 0, statusVal);

                int rc;

                rc = client.WriteTag(tag, DataTimeout);

But I am receiving the status code of -32 or -4.

What is the test debug for windows and should I use this string in the commad prompt?

[Kyle]

Ah, OK, you are using a wrapper.  Looks like C#?  Which wrapper are you using?

Error 4 is means that the library received weird or unexpected data from the PLC or as input.   Error -32 means a timeout.

You can download the C DLL and compiled tests and examples here.  Pick the right ZIP file for you Windows CPU type (64-bit or 32-bit x86).   Unzip that into a directory somewhere and you will see the plctag DLL and tag_rw.exe executable.   Make sure those are in the same directory and run the executable on the command line (cmd.exe works fine). 

I do not remember how to redirect output on Windows.  Maybe is it ">" as in Unix-like systems?   I do remember that the tag string must be in double quotes.  It looks like it would be something like this:

tag_rw.exe -t bit -p "protocol=ab-eip&gateway=192.168.1.99&path=1,0&plc=ControlLogix&name=CommFromPalletizer[0].3" -d 4 > log.txt

In typing this up I noticed that your tag name uses a colon ":" for the bit field.  In the core C library it is ".".   Instead of "CommFromPalletizer[0]:3" make sure you use the tag name "CommFromPalletizer[0].3".

If you get back a good value from the tag_rw.exe program the we know that the core library is working fine with your tag.   Once that works try adding a write to the bit:

tag_rw.exe -t bit -p "protocol=ab-eip&gateway=192.168.1.99&path=1,0&plc=ControlLogix&name=CommFromPalletizer[0].3" -d 4 -w 1 > log.txt

If the bit is already 1, change the 1 to a 0 (zero).

I hope this helps!

Best,

Kyle

Hi,

Did you get any more output than that?   There should be a lot of lines like this:

I am using the next version of the library which has not been released yet, but the only difference is the Pascal wrapper.  You should see the logging above with all the time stamps and thread information.   That tells me what the library is doing internally and you can see the individual packets to and from the PLC.

I looked up the Windows redirection command syntax and the command line you should run will look like this, notice the part at the end after the log.txt file name.  That is very important to redirect stderr into the log:

tag_rw -t bit -p "protocol=ab-eip&gateway=192.168.1.99&path=1,0&plc=ControlLogix&name=CommFromPalletizer[0].3" -d 4 > log.txt 2>&1

Then the log information will be in the file log.txt.  Make sure to double check that your PLC is:

1. A ControlLogix, if not, please correct the type.
2. That the CPU module is in slot 0.  That is what the path is saying.   If it is not in slot zero please correct the last number in the path to the correct slot number.
3. That you have the correct tag name.  You can use the list_tags.exe example program to list tags.  You would run it like this on the command line:

C:\somedirectory> list_tags "192.168.1.99"  "1,0"

Can you please try that and attach the results here?

Kyle

Hi Kyle, 

I have listed down all the tags and it came into my knowledge that tags was not listed in the plc? Is the tag not created or I am not able access that tag? What could be the possibility?. Please find the attached log file as well.

[Kyle]

Hmm...  Yes, it looks like you have either the wrong name or the tag is not there:

2021-01-30 07:42:18.337 thread(1) tag(0) WARN check_read_status_connected:1541 CIP read failed with status: 0x4 IOI could not be deciphered or tag does not exist.

I found this in the log.   The PLC is saying that your tag, as named, does not exist.   Is it a program tag?   There are at least two "levels" of tag, the controller or top level, and then tags in each individual program.

When you list the tags, what do you see?   Can you send that to a log file and attach that?

list_tags "192.168.1.99"  "1,0"  > tags.txt   2>&1

If your tag is a program tag, it will be in the list, but with a prefix something like this: Program:SomeProgram.CommFromPalletizer[0].3.

I am not sure if the tag will be listed if it is protected from access.

Best,

Kyle

[ms ns]

I am attaching the list of tags. Let me know the possibilities why am I not able to read or write it. Or if I want to how can I achieve that.  

[ms ns]

Hi Kyle, 

Any help for this?

Regards

[Kyle]

There appear to be only three possibilities:

1. The tag does not exist in that PLC.  I.e. you have the wrong PLC.
2. The tag is protected from use and you cannot see it from outside the PLC.
3. The tag is under a different name.  Is it perhaps a field of some other UDT?

Use Studio 5000 to see where this tag is and what the name should be.  If it is public and in the target PLC, you will be able to read and write it.   If it is protected and not visible from outside the PLC, you will need to make it visible or make a visible alias for it (I think that works, you will need to try).

At this point it looks like all the possible solutions are outside the libplctag library.

I hope that helps!

Best,

Kyle

Thanks so much.

Hi Kyle,

So a new tag is created CommToInfeed[0].3 and I can actually read and write it from cmd but when I try to read it through code I get an error of Err_Bad_Param The status code of -7. Here my connection string

 protocol=ab_eip&gateway=192.168.1.99&path=1,0&cpu=LGX&elem_size=4&elem_count=4&name=CommToInfeed[0].3

[ms ns]

Please find the attached debug screenshots. 

[ms ns]

I cannot add the Tag name as CommToInfeed[0].3 whereas when I change it to CommToInfeed[0] the status code 0 is returned. 

[ms ns]

This is the output from the cmd

Done

 

But when I access the tag CommToInfeed[0].3 from code it returen -4 error status code.

Hi Kyle,

Any idea why am I getting this error code while trying to write on a bit of an array?. Any help would be appreciated.

It looks like the wrapper may not have a recent version of the C DLL.   What wrapper are you using?  This would be the C# library.   Are you using the one from the libplctag GitHub organization? 

Please make sure you use the latest version from https://github.com/libplctag/libplctag.NET.   That contains the latest version of the C library.   Note that you may need to use the low level code to access the bit functions to get and set single bits.

Best,

Kyle

[ms ns]

What exactly do you mean by low level code?

[ms ns]

I used that code as well but same exception of error bad param. 

[ms ns]

What should I do now. 

[tim...@gmail.com]

Get it working by reading/writing the whole DINT first, and code up some Bit Masking to access individual bits. https://www.arduino.cc/en/Tutorial/Foundations/BitMask

Try to fit this to your needs: https://github.com/libplctag/libplctag.NET/blob/master/src/Examples/CSharp%20DotNetCore/ExampleArray.cs

To access as a DINT. For the tagname, use CommFromPalletizer or CommFromPalletizer[0], not CommFromPalletizer[0].3

For further reading, there are many examples for you to study:

* https://github.com/libplctag/libplctag/tree/release/src/examples

* https://github.com/libplctag/libplctag.NET/tree/master/src/Examples

When Kyle said "low-level code", I believe he is referring to using the C API methods (specifically the bit handling methods), rather than higher-level methods.

Documentation is here: https://github.com/libplctag/libplctag/wiki/API#handling-single-bits.

[Kyle]

I did some experimentation.   This is with the C DLL methods.  

I accessed the tag TestDINTArray[0].8.   But I treated it like I was accessing a full DINT.   I did not use any of the bit methods.   I just kept reading it and writing it as if it was a full DINT.   I got only the values 0 and 1 as expected.  And I can write it using full DINT values, but only that one bit changes.   So if I write 0, the bit becomes 0.  If I write any non-zero value, the bit becomes 1.   The bit tag internal flag is "sticky" in that it keeps working even if you use the other integer data accessors.  Once you tell the C DLL that you are dealing with a single bit, it will remember that and only change that bit.

You can tell the wrapper code that you are accessing a DINT and you will only get the values 0 and 1 back depending on the value of that single bit.

Please follow what Tim said first: get it reading and writing a full DINT.   Then you should be able to just add the ".3" to get the tag name "CommToInfeed[0].3".

Without a debug log from the code, I cannot tell why there is an error.   Is the wrapper doing some parsing of the tag name?

Best,

Kyle

I have successfully read and write to the bit of index array. What I did was create a batch file and executed the cmd commands. It really worked like a charm. 

[ms ns]

But kyle what would be the cmd command for the bool tag. How can we read and write it through cmd?

I do not understand the question.   Are you trying to use the library with a batch file running tag_rw or are you trying to write code in C# to do this?   Can you please explain?  In order to help you it is important that we learn:

• what platform you are using: Windows, MacOS, Linux...
• The version of the C DLL you are using.
  
• what language you are programming in, C, C++, C#.   And what version of the wrapper, if any.
  
• The tag name and type.
• The type of PLC.
• Example code that shows what you are trying to do.
  

With these things we can try to help more.   Without them, we are not able to give you and pointers.

Best,

I basically needed to write on to a tag. So I created a batch file with cmd tag_rw command in it and executed in the code. It worked as well. I am using the C# library and once I am done with the whole work I will post my code and logic as well.

But there's one thing that I needed to ask..how can we read/write boolean data type tag in plc?

If you want to write a boolean type (not a single bit) you can just reference the tag name.   You will get back a single byte with 1 or 0 in it.  You can write it as well by using the uint8 data setter.  If you have a boolean tag, myHappyLittleBool, you just use that as the name.   If you need to provide a data type, use a byte or uint8.

If you want to access a boolean array, you will get back an array of DINT of the total number of bools in the array divided by 32, rounded up to the nearest multiple of 32.   Rockwell packs boolean arrays like this.   It is a pain to access these because you need to treat them as DINTs and either use bit tags or use masks in your code to set the bits you want.  

If you want to access a single bit in an integer type, you add the ".<bit#>" notation at the end of your tag name as you did in the examples from before.  These are bit tags.

I hope that helps!

Best,

Kyle

[ms ns]

tag_rw -t byte  -p "protocol=ab-eip&gateway=192.168.1.99&path=1,0&plc=ControlLogix&elem_size=1&elem_count=1&name=TagName" -d 4 > log.txt 2>&1

byte data type is not a valid one. Used the uint8...so it returns data[0]=255 (ff) which means the tag value holds 1?  

[ms ns]

I have a single tag to access to not an array this time.

You can use bool type if the wrapper supports it.  You just access the tag with its name.   You do not need the special bit format.   In that case, you should write 0 for false and 0xFF for true.

Kyle
