Hi, Im not sure if this is what you mean, but i do succesfully use the IoDrvEthercatLib.ETCSlave.InputData and IoDrvEthercatLib.ETCSlave.OutputData to read from and write to beckhoff DI and DO cards. Very convenient as you can make an FB with an VAR_IN_OUT of type IoDrvEthercatLib.ETCSlave and only have to pass the slave reference... So i am not using .ETCSlave_Diag but .ETCSlave...

We are using codesys 3.5.16.30 and we have a array with strings of length 5000. We are having issues subscribing to this variable from an OPCUA client. Is there any limit in the OPCUA Server in codesys for how long an array can be on the opcua server?

Hi, I am currently creating a documentation for our library with DocScripting. In the process, I noticed that Visu images are created before the merge and transform, i.e. "screenshots" of the different Visus. Unfortunately, these are not used in the later process (Merge/Transform). Is there a way to set it up so that they are found in the html file?

Post by westcountryewe on ac_persistence not working when creating a Boot Application but works with a Direct Download to the PLC
CODESYS Forge
talk
(Post)
I am using V3.5 SP18 Patch 5. I have noticed that when I Create a Boot Application from CODESYS, and upload this to my PLC via a USB stick the AC_Persistence does not work and none of my values that are in my PersistenceChannel are retained. However, if I connect direct to my PLC and I perform a direct download of my CODESYS program, my values that are in my PersistenceChannel are retained and work as they should. This makes me wonder if there are files that are missing when a Boot Application is created. I have tried taking a backup of my configuration files after performing a direct download, which gives me the plclog.zip folder, and appears to have the ac_persistence folder present within the file structure, however when I replace the plclogic.zip with the same folder that was created when I created a Boot Application, it still does not work but I wonder whether this is because the ac_persistence folder isn't stored in the correct location for reading. The .app and .crc files are embedded within the plclogic.zip folder, which obviously when uploading need to be standalone files in the root directory of the USB, so the intention there is clearly to extract the .app and .crc files and put them into the correct location within the USB. I wonder if it could be the same for the ac_persistence folder? I have tried moving it to different locations but none have worked. Has anybody else discovered a fix for this? I know the short-term solution is to do a direct download to the PLC but there are some logistical reasons why this isn't neccesarily the best solution for us.

Is there a way to links these X and Y values from the properties to an integer defined in the main program? Note that I just want to use them and not change any of these coordinates in the program.

I don't know the root cause... But what could help to continue when it seems to hang, is stop the CODESYS (communication) Gateway. Go to the Windows SysTray, find the icon for the Gateway and then stop it and start it again. This will interrupt the connection between CODESYS and your controller.

Post by john-robinson on Limiting Memory Access of an Array to Within its Bounds
CODESYS Forge

Recently we had an issue regarding some simple code to calculate a rolling average. The code indexes from zero to 199 to properly store the current input into a circular buffer which then allows us to calculate a rolling average: VAR input_5s : REAL; outs_arr : ARRAY[0..199] OF REAL; i : USINT := 0; END_VAR ___ //this code runs every five seconds, calculating a rolling average outs_arr[i] := input_5s; i := i + 1; output := OSCAT_BASIC.ARRAY_AVG(ADR(outs_arr), SIZEOF(outs_arr)); IF i >= SIZEOF(outs_arr) THEN i := 0; END_IF There is a simple bug in this code where the index will be set to 0 when it has surpassed the length of the array in bytes (800 in this case) rather than larger than the number of reals in the array (200). The solution here is simple, replacing i >= SIZEOF(outs_arr) with i >= SIZEOF(outs_arr)/SIZEOF(outs_arr[0]). In this example when the index increased to 201 and the line outs_arr[201] := input_5s was called, codesys arbitrarily wrote to the address in memory that is where outs_arr[201] would be if the array was that long. I would like to find a way to wrap the codesys array inside of a wrapper class that checks if an input is within the bounds of an array before writing to that value. I know how I would implement that for a specific array, I could create a method or class that takes an input of an array of variable length, ie. ARRAY[*] OF REAL, but I don't know how to make this for any data type. I am wondering if anyone has ever done anything similar to this, or has any better suggestions to ensure that none of the programmers on this application accidentally create code that can arbitrarily write to other locations in memory.

Hello, I think you can try to change the Connection from Multicast to Point to Point. Please also make sure your windows firewall is allowing the correct UDP ports inbound for ethernet IP. You might also need to increase the RPI, so it times out slower.

You can use the switch frame variable, but there should be a variable for each active visu user. You can put the switch frame variable in an array, and use CURRENTCLIENTID as index into the array to get what you want. The CURRENTCLIENTID is assigned to new users automagically by the Visu Management.

I've already experimented with two methods, but unfortunately, they only function with projects of type *.project. Consequently, when executing: system.commands["staticanalysis", "run"].execute() For the 2nd Option: You'll need to ensure that in the Static Analysis Settings, the option "Perform static analysis automatically after compilation" is checked. # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code()

So I think I've found a way to do what I want, but its a not as simple as I thought it would be. Essentially I've got to put my "logic" that decides what the GVL variable should be at the start of every task (rung 1). Then regardless of what the force is the variable will be set to what the logic decides.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
