Post by thewizard8 on Raspberry PI4 Serial Port ^{CODESYS Forge talk (Post)}
Hi Dear All, I'm using my raspberry PI4 as a CoDeSyS PLC (Build from scratch with custom electronics). I was able to implement all fieldbuses with the exception of Modbus Serial. I'm using the internal Port (GPIO) and I configured it in /etc/Codesyscontrol_user.cfg the following away: [SysCom] Linux.Devicefile.1=/dev/ttyUSB0 Linux.Devicefile.2=/dev/ttyS0 I'm using COM2 on Master configuration. I'm using a interface board from TTL/RS485 (bidirectional board), and it's works perfectly with other devices but not in CoDeSyS. I'm able to send data with python script and read it on my pc using putty, but when I use a modbus slave simulator to interface with codesys I always get red icons on master and slave. (Please find image attached). I'm pretty shure that this might be a bad parameter on my CoDeSyS runtime configurstion file. Can someone help me? I'm stuck and this is for my master degree certification.

Post by berto on Opening PDF in Web Browser in Target Visu HMI ^{CODESYS Forge talk (Post)}
Hi everybody, I've been facing problems with the PDF visualization in Web Browser. I am trying to open a pdf file called 'sample.pdf' which I manually saved inside PlcLogic/visu folder. I am setting the web browser URL as: 'http://127.0.0.1:8080/sample.pdf' but I get 'refused connection'. I got a similar error trying to open https sites and I discovered that I can only open http websites. Opening 'http://de.wikipedia.org' everything works fine. I also tried to check using code whether the sample.pdf is present in the directory. Unfortunately, when I try to read directories of 'PlcLogic' I get file FILE_OPERATION_DENIED (I am using File.DirList). I would like to be able to open PDF files in web browser. Possibly to move new PDF files in the folder as my customer wants to display different pdf manuals on the hmi. Here you find some screenshots and my .project. I am using Codesys 3.5.19.70. Best regards, Berto

Post by rossanoparis on Upgrading CODESYS runtime from v4.7 to v4.9 using a bash script leads to lose the licences stored in the soft container ^{CODESYS Forge talk (Post)}
System information - Controller: KUNBUS RevPi CONNECT-S - OS: Linux buster 32bit 5.10.103-rt62-v7l #1 SMP PREEMPT_RT armv7l GNU/Linux - CODESYS v3.5 SP19 Patch 2 I'm facing a problem related to codesys licences using a procedure based on a bash script. Such bash script detect the presence of new .deb files and install them on system. My automation solution don't allow to be maintained by dedicated personal, thus even the CODESYS runtime SW must be installed using an "automatic" procedure instead of using the CODESYS tool. remark I've been using the following procedure since the runtime v4.5 without any issue. Before installing the new runtime packages, I need to copy the file CODESYSControl_User.cfg (here attached) because of new section which is necessary to add in order to allow some folders to be written by CODESYS runtime v4.9 Up to now, this has been unnecessary, this is the main difference between my previos bash file and the new one. remark If I skip this action, everythings goes fine, but my CODESYS application can't work as it needs to access some folders on controller's file system. Process - Before the procedure: the licenses are OK (see attached file lic-01.png) - After the procedure: the new CODESYS runtime version is correctly installed, but the software container with v1.19 and all licences disappear (see attached file lic-02.png) This is the synthetic content of bash script I'm using. # Stop runtime sudo service codesyscontrol stop sudo service codesysedge stop # Move the new CODESYSControl_User.cfg file # New configuraton with folders declared sudo mv -f CODESYSControl_User.cfg /etc # Install runtime package echo N | sudo apt-get install -y --allow-downgrades codesyscontrol_raspberry_4.9.0.0_armhf.deb # Install edge gateway package echo N | sudo apt-get install -y --allow-downgrades codesysedge_edgearmhf_4.9.0.0_armhf.deb # Reboot controller sudo reboot Thanks in advance

Post by hanpekel on Reading request counter value from modbus server in application ^{CODESYS Forge talk (Post)}
Any way I can read the value of the 'request counter' (see screenshot) in my application. Amount of client connections is easily found using ModbusTCP_Slave_Device.uiClientConnections; But for request counter it does not seem to be that simple.

Post by tcarlbom on Read tag values using external program ^{CODESYS Forge talk (Post)}
This is my first time posting in this forum and I am new to codesys. I am a fullstack developer and I am trying to figure out how the following. What would be the best approach to create a own/custom tag browser? Either directly in codesys ide or using a separate custom program (perhaps a winforms application). 1.a. Shall I parse the .project xml file to get a list of all tags in the project? 1b. Shall I use python scripting in codesys ide to get a list of tags? Once one have selected some tags. These tags shall be exposed to a python program which will be acting as a edge computer. It’s fine to be able to import a file. 2a. I found a library called codesys plchandler which (as I understand) acts a rest api server. Is this correct? If so, can I query the api from a custom python script, ie can query what tags exist in project and or read tag values? My research so far. From earlier projects I know that using opc ua would be perfect for this but from my opinion it’s bloating the plc since it’s resource intensive. So opc ua is not an option. Codesys automation server is neat. But I don’t want to rely on some cloud services and subscription based pricing. There seem to be several interesting codesys libraries like mqtt, tcp server and NVL sender which would help me expose plc tags. But all have a common problem. One have to manually write what tags which will be used in these function blocks. I want a similar experience like “selecting” tags in the opc ua or the codesys tracing, ie a tag browser.
