Post by kbazzett on "Sequent Microsystems" industrial automation hat raspberry pi ^{CODESYS Forge talk (Post)}
Here is a complete list of the Sequent Microsystems Pi hats that work in Codesys. https://github.com/SequentMicrosystems/SM_CODESYS/tree/main/ "For easy install download the .package file and open it on your computer, Codesys installer will know what to do with it." <- This. The Multi I/O Hat fit my needs because of the Analog I/O 4-20ma and RTD. I used a Raspberry Pi 5 and 64b install. The example project is also worth the download. With the sample project open, right click on the Raspberry Pi device and update to whatever you are using (SL, MC, 64b). Enable I2C on the PI. You can jumper the hats Analog Outputs to Inputs and see it function on the Web Visualization. Very Cool! I spent quite a bit of time trying to find this solution so hopefully this update helps others. Here is the video link on how to setup a Raspberry PI as a Codesys PLC https://youtu.be/RPoPscbo3Kc?si=Th4-n-mQ6g5fdHj8

Hi. I have a problem with MODBUS TCP MASTER. I treid to read HR in range 3027-3037 but I cannot read them. I have modbus slave chanel with offset 0x3037. I checked what I read and it looks like I am reading HR in range 1-10. What I am doing wrong.

Post by kurtk on Modbus TCP Server ^{CODESYS Forge talk (Post)}
ditto I'm just getting my codesys wheels on and the modbus stuff is confusing. I am re-platforming an existing PLC application On that platform one could simply tag variables to register numbers and the whole shooting match could be accessed via modbus and typically holding registers and input registers were treated the same way... On codesys I see there is a modbus TCP server Device I/O mapping tab and a Modbus TCP server IEC objects tab I get the sense that one can configure the serving of variables both/either way but am unclear about the optimum/necessary path. Apparently in the IEC Objects tab one can "ADD" something or other - presumeably channels. I have created a preliminary function block but the Select Function Block window shows nothing to select WTH ? I exported the Device mapping and was surprised to see the entire Device IO map - complete with all the bit-mapped holding/input registers!! WTH!!?? Bit-mapped words are strictly a nichey special purpose application. I am targetting making a couple hundred variables available which would turn into hundreds of pages of IO/mapping Is the FUnction Block IEC objects thingy an alternative to that ? I notice that CODESYS shows the tags which the PLC used to specify the register address... are tags used in CODESYS for any specific hard-core purpose ?

Post by jv-certhon on Io driver Scan functionality ^{CODESYS Forge talk (Post)}
Hello, Codesys IDE is 3.5.21.30 IoDrvBase is: 3.5.17.8 I am working on implementing Codesys on our I/O product line, using the IO driver examples, and the Linux UDS socket approach. I have sucessfully created an implemetation where I have a Device with mutiple slots, on which I can plug modules. These modules represent our IO modules, and communication is successful. (For this question the assumtion can be made that Codesys commucates with 1 'master' device, which handles further communcation with the IO modules. For the next part of the question it can be assumed that the Master device has a list of which modules are attached/available) I'm now trying to implement the 'Scan for Devices...' feature, but I'm completetly lost on what to do once the IoDrvScanModules method is called in my IoDrvFB. I'm guessing that the ppConnectorList has to be filled with the found devices, but I have no idea if that is the correct approach. And Codesys is not triggering my breakpoints in the method, which makes things more difficult. I hope someone could provide some examples or guidance on what steps I should take to implement the scan feature. Thanks in advance.

In fact, specifying to use SM3_Basic library in version 4.14 fixes the issues, choosing 4.16 raises the same issues. (Library Manager > Place Holder > Double click on SM3_Basic > Show all versions)
