Post by hanoues on Holding brake release ^{CODESYS Forge talk (Post)}
I've tried using the SMC3_BrakeControl function block to control the brake, but unfortunately, it's not functioning as expected. Despite setting the appropriate parameters and inputs, the brake control does not operate correctly. Any insights or suggestions on resolving this issue would be greatly appreciated. STATE_MANUAL.UNLOCK_BRAKE: IF Button_release_brake THEN GVL.drum1_Control_Brake:=TRUE; FBA.T11_ContBrake.bExecute := TRUE; GVL.manual_state := STATE_MANUAL.WAIT_FOR_BRAKE_RELEASE; END_IF STATE_MANUAL.WAIT_FOR_BRAKE_RELEASE: IF FBA.T11_ContBrake.bDone THEN FBA.T11_ContBrake.bExecute := FALSE; GVL.manual_state := STATE_MANUAL.WAIT_START_BUTTON; END_IF

Hallo Tim, man hat halt einfach mit der Control Win - keine wirkliche harte Echzeit. Man müsste den Fehler genauer analysieren + ich denke er müsste den Slave wieder an den Busholen oder fällt ads ganze Netzwerk aus? Welche Versionen genau sind im Einsatz? Ist das halbwegs aktuell (PN 4.4.0.0?) Grüße Edwin

CODESYS runtime version 4.9.0.0 for your Pi. ssh user should be pi. This is for RasperrPi Os 32 bit. If you are on RasperryPi OS 64Bit use Arm 64bit SL product as Runtime.

Post by ofey on Codesys Soft PLC OPC UA server ^{CODESYS Forge talk (Post)}
Hi! I'm sorry if this has been asked before. I have tried looking up previous topics regaring this, but even though I'm following tutorials and other posts I cant seem to get this to work consistently. I actually got the connection established on a test project after some trial and error. I only got it to work with the "Anonymous login". But after i deleted the test project and tried to get the same thing to work on another project I cant get it to work anymore. What I'm trying to do: Set up and OPC UA Server using CODESYS with the free soft PLC. I then try to connect to the OPC UA Server with the program "UaExpert". What happens: I get the error Error "'BadUserAccessDenied' was returned during ActivateSession". What I have done in CODESYS: - Added the object "Symbol configuration" and checked some test variables - Checked "Support OPC UA features - In "Communication settings -> device -> Change runtime security policy" I have checked "Allow anonymous login" What I have done in UAExpert: - Found the OPC UA server under "local". (It is showing two servers though, I do not know why. It showed the same when it worked yesterday). Se attachment - Checked "Anonymous" under "Authentication settings in the OPC UA server. I'm new to CODESYS, so it could be something elementary wrong in my settings. Maybe something in the user settings in CODESYS regarding user rights or something?

Post by andrej on Write to File on soft PLC winV3x64 ^{CODESYS Forge talk (Post)}
Hello all, I would like to store some data in text file. I use the soft PLC Win V3x64, on Windows 10. I use the SysFile Library 3.5.17.0. If I store the file directly in the in the directory of the PLC i.e. in '/CODESYSControlWinV3x64/E1FA7ABE/PlcLogic/LogAU.txt' the file is correctly filled with the data. However, If I use an absolute path to a different directory no data is stored in the respective file. Despite the fact that the respective file exists and the Filehandler is correctly opened (see in picture _fdSysFHandle <> -1). // sFileName : STRING := 'LogAU.txt'; // STORES FILE IN ../CODESYSControlWinV3x64/../PlcLogic/LogAU.txt' sFileName : STRING := 'C/Temp/LogAU.txt'// DOES NOT WORK --------------------- // FILE DESCRIPTOR _fdSysFHandle := SysFile.SysFileOpen( szFile:= sFileName,am:= SysFile.AM_APPEND,pResult := ADR(_Result)); Does some have an idea where the problem is, resp. how I can get store a file in an arbitrary directory. Thanks a lot and kind regards Andreas

..dann mal im WBM alles deaktivieren, da der OPC UA Server ja direkt im PFC200 SL RUntime integriert ist und nicht über die WBM Oberfläche zu konfigurieren ist.

Post by ofey on Testing of Codesys program ^{CODESYS Forge talk (Post)}
Hi! I thought to hear what you guys think is the best way to test the program in my scenario. I have some PLC programs that have been made and deployed on different PLC's. The program has added the specific devices and IO that is applicable. I have made a test environment for everything outside of the PLC, ie. the same SCADA system that is talking to the PLC, and a program running locally is simulating the plant (level regulation of different tanks). Pr. now I have had to manually change the variables that are reading/writing values from the IO so they read/write via OPC instead. I also have to change the device tree from the specific PLC rack, to the soft PLC. So I kind of end up with two different programs that I have to maintain. I was just wondering if you believe there is an easier way to do this. So I can have the exactly same program and kind of switch between the soft mode, and the "real" mode.

Agree! Me and my customers are buying SL Licences from the store but we don't get proper documentation of the runtime! Only a few hints of the entries in CodesysControl.cfg are spread all over the Internet.

Post by timvh on Having trouble using the Web Client SL library ^{CODESYS Forge talk (Post)}
it should be something like: fbWebClient : WEB_CLIENT.WebClient; You need to use the "Namespace" of the library, not the name of the library itself.

Edited: Thank you, after further inspection the library is unavailable in the example project for some reason, but using the correct Namespace in my project solved the problem.

Are you using the Wago Runtime - please check the version information on scan. Either 6.x.x.x or CODESYS 4.x x.x SL Runtime- and always check the plclogger in such cases.

Post by aris on Modbus write via FB failure ^{CODESYS Forge talk (Post)}
Hi all, I am using CoDeSys V3.5 and a soft controller Win V3x64. I am trying to read a modbus slave via Function Blocks and not via the channels of the hardware tree for the Slave. I created some requests of type ModbusRequest and I notice that I can read Input Registers and Coils but I can not write Holding Registers and Coils. I am using the library IoDrvModbusTCP 4.1.0.0. When i just use a single modbus request with FC06 (or FC16), there is no request sent to the slave and although the xExecute takes its true value from a pulse of 2 seconds duration, I take almost every 3 minutes an error "TCP_COMMUNICATION_ERROR - 16#A5 - TCP Port. error. Request was not sent". My code is ok because if i change the function code for reading registers, everything works fine. Did anyone have this issue in the past? Thank you in advance.

Post by brubingh on Download Missing Libraries not working ^{CODESYS Forge talk (Post)}
We are working on a project and the customer required 3.5.16 BF4. After working on the project for a few weeks I opened it the next morning and it could not access libraries. IecVarAccess could not be accessed. I checked if windows updated - it did not. So no explanation for why it lost access other than that I shut down the computer for the night. Note that I am using a demo license. I still haven't figured out any reason to purchase a license. So I spent the next hour reinstalling CodeSys. Note that I did NOT uninstall first. After install I waited another 5 minutes for it to open the first time. I clicked File->Open to open the project. Previously I had selected File->Recent Projects - not sure if that makes and difference. But after this process it did open the project and compile it just fine. This is miserable. If this had happened when I went on site to a customer I would have lost hours of work doing the reinstall. Is there a different and quicker fix?
