Post by pierre on difference between stub file and source file in scriptengine ^{CODESYS Forge talk (Post)}
I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

Post by jmohre on External file with relative path ^{CODESYS Forge talk (Post)}
I try to add a simple text file to my PLC application, so that is download everytime the application is downloaded to the target. What I did is to add an external file to the application and this works perfect as long as the external file location does not change. It looks like the external file path is stored absolute in project. But if different users work on the project they may have different locations where for their working directory. Is there an option to store the external file path relative e.g. to the project file? Or does s.o. know a different solution to add a text file to application in order to download automatically with the application? Thanks

Post by mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
Following up on the invalid user authentication on the target Not 100% sure what the problem was but following my post I managed to create an administrator level user. Then my next issue was that I could not connect to the device. I might have flipped the device from a 64 bit version to a 32 bit version so I did UPDATE DEVICE back to the 64 bit version; still could not connect somehow. Then I did two things at the same time that fixed my problem: Wiped the Codesys Control Win 64 bit version and installed the 32 bit version Installed latest Codesys Control Win V3.5 SP20 (released today) I wish I knew which one of these actions fixed the problem but at least the problem is solved. Hoping this post may help someone one day

Post by mgengler on Recipe Manager - Not Creating Recipe Files ^{CODESYS Forge talk (Post)}
Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only. Can't figure out what is missing...

Post by martinlithlith on Mux I2C ^{CODESYS Forge talk (Post)}
Hi! I´ll try to get this thread going again as i´m having simliar problems. Right now i get a red triangle on my connected devices (i´m testing with a BME280 sensor and a PCA9685 resvo driver). The TCA9548 have the green symbol beside it. On the "red" devices i get that the bus is not running. I have tried to either run it using the parent bus cycle setting or creating a new freewheeling task prio 1 but nothing helps. I have compared my settings to the settings from the example from the MUX package and i have read (i think) every thread in forge that could be of interest. EDIT: The ic2detect only shows the mux (70-70) and the servo drive (70-76) so i´ll look in to if i managed to burn the 280-sensor while soldering). Another question regarding the 280 sensor. I have a sensor GY-BM E/P 280 that should record humidity and temperatur. Could this be a problem with the library? Does anyone have an idea of what i might be doing wrong? I have some experience from Codesys but not much so this could be an easy one. All suggestions are welcome. I tried to upload the project archive but it did not work. Should i upload the export or how could i show you my horrible project? Best, Martin

You could create a DUT of the Type Union and add an array of 2 bytes + an Int. Then write the byte values in the array of the Union and read the Int. Or VAR iInt : INT; byHigh : BYTE := 2#1111_1111; byLow : BYTE := 2#1111_1111; END_VAR iInt := TO_INT(byHigh*16#100 + byLow);

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.

Post by davidbo on i2c How does CODESYS handle exception or error messages. ^{CODESYS Forge talk (Post)}
For Raspberry Pi I have made a python script which regularly read a bulk of data over the ic2 from a device. Sometimes I get an Exception an IOError. I assume similar things can happen in CODESYS. So how does CODESYS handle that? Can I get any info about such an event?

Good morning, mecke96. Exactly the same thing happens to me, although I have not done the part of executing a .py file. It only reads the temperature and the counter, but the other values are zero as in your image "no readings". I have tested the MPU6050 device on an Arduino and it works. Could you tell me if you solved it?

Post by wiresplus on Cannot get INT_TO_TIME working ^{CODESYS Forge talk (Post)}
Hello, I have a simple TON timer. It is watching prime loss for a pump. The operator can set the delay via the HMI, it is an integer (seconds) As the TON uses milliseconds, we then multiply the entry by 1000 to get seconds. Seems simple, but... VAR PrimeTimer : TON; primetime : INT; END_VAR PrimeTimer(in:=State>0 AND FlowRate<MinimumFlow,pt:=INT_TO_TIME(primetime *1000)); For an entered 15 seconds (VAR primetime:=15;) the timer reads 49d17h2m26s760ms !!!! What am I doing wrong?

i had a similar problem trying to send files to C: on local computer. Ended up using Oscat ftp to transfer file with filezilla. i read there is an "write protection", possibly to do with windows, issue with sp19 and up. there are some config files in the codesys dir you can change, which may help. after i was able to transfer to local PC\downloads but not c: so went the ftp route. works well. https://forge.codesys.com/forge/talk/Runtime/thread/5cac1390b4/

Post by acc00 on Redundancy Codesys Runtime, Synchronization ^{CODESYS Forge talk (Post)}
Hi, I’m currently testing the Codesys Redundancy application with 2 Raspberry Pi, with the idea is of using in my project 2 Wago PFC200 and 1 Ethercat Master with 2 Remote IO. After I configure the redundancy, and one Pi is Active and the other is Passive, if I disconnect the Ethernet cable of the Active, the Passive become Standalone, which is good, but the problem is the following: -When I recover the Ethernet connection, both stay Standalone. They will NOT Sync until I do it manually in the Codesys environment. How to make the synchronization automatically? -If both Pi/PLC stays Standalone, who is managing the IO? (Ethercat and Serial) I have done a test with an Modbus Slave, where I am sending a counter that increase every second. And I see that when both PLC are standalone, they both keep an active connection with the Slave, and both write values. This does not seem good, since according to this in my project both PLC would try to control the IO at the same time. Note: The Codesys have an option (greyed out, not possible to select) which says “Auto Sync”. What is the purpose, and why I’m not able to select it? I'm using Codesys Control for Rapsberry Pi 64SL Runtime in my test environment (2xRaspberry Pi 4), with the idea of using Codesys Control PFC 200 Runtime in my project (2xWago PFC200 and 1 Ethercat Master with 2x Wago 750-354 Ethercat Fieldbus Coupler). Using the last Codesys 3.5 version (SP19 PAtch 5). I'd appreciate a lot any help on this questions!

Post by tim-roelant on Profinet fault with codesys control V3 - Receive packet error ^{CODESYS Forge talk (Post)}
I have set up a brandnew Beckhoff panel pc with a codesys control runtime V3. I configured it together with 2 profinet field devices: a 16in/16out IO module from Turck and an MTS linear encoder. The machine works fine untill all of a sudden the communication breaks and the profinet participants become unreachable. At that point I can still ping the device, but the profinet master does not find them anymore: When i do a scan they are not found. When i do a cold restart, the profinet master becomes active again and the devices are found again. In the log i get Ethercat packet receive error: sysethernet. I am a little confused, there is no ethercat device in the device tree. I already set the send clock and the reduction ratio to higher values, but without result. Can codesys be configured, so that the communication re-establishes without doing the cold reset? This is very annoying and is causing a lot of prodution losses. regards Tim
