Post by timvh on Persistent Retain Variables Not Visible in Online View (WAGO PFC100 + CODESYS) ^{CODESYS Forge talk (Post)}
It is a known issue. It only happens with CODESYS and Wago controllers and the Persistent Variables. It seems related to using 64 bit variables in the PV list (e.g. LREAL). Internally in the PLC everything works okay. It is just a monitoring issue.

Hello, Im working with EPEC PLC's and working on the HMI and i'm running into the following errors: Unknown Type ISOImages.TargetContainer.TDS (and similars) I cannot locate the error and the source position is the visutalisation manager where i cannot find anything related to this type. Im working with: Codesys V3.5 SP18 patch 3 and i cannot update since the hardware does not allow for newer SP versions

Post by faceplant on Comparison via CLI is broken ^{CODESYS Forge talk (Post)}
Hello! I am trying to compare 2 projects via the --compare CLI option. In the docs for the --compare option, it describes the usage as .\CODESYS.exe --compare "project path 1" "project path 2". I store my projects in WSL2 on my windows machine. Since CODESYS is happy to open those projects via a path like \\wsl.localhost\home\project.project. So, to compare, I use the command .\CODESYS.exe --compare "\\wsl.localhost\home\prog1.project" "\\wsl.localhost\home\prog2.project". This results in CODESYS just opening the project and starting, not comparing the two projects. No errors are thrown, and I know the paths are correct since I can open both independently in CODESYS, and I can compare them manually through the CODESYS UI. I have also tried moving my projects to the Windows 11 OS and still have the same issue. CODESYS opens the project and does not actually compare them. I am using CODESYS profile v3.5 sp20 patch 1. What is the correct way to compare 2 projects using the --compare CLI option?

Post by rabaggett on CODESYS control for Raspberry Pi 64 SL errors ^{CODESYS Forge talk (Post)}
Hi, I am trying to create a project using a raspberry pi, I have added the modules for the Pi and MCP3008. I have encountered som errors that I don't know how to track down. 1. The GPIOs give preprocessor errors, but I read that this does not prevent compiling. This seems to be true. I can build the empty project with no errors. 2. After adding a SPI master and MCP3008, the preprocessor errors double, but seem similar and the project again builds with no errors. 3. I add a DUT and GVL, with a function, and I get the following errors. They remain even if I delete these things. ------ Build started: Application: Device.Application ------- Typify code... [ERROR] crr: C0032: Cannot convert type 'Unknown type: 'ADR(GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7.Io_17160064_c083_41f8_9e53_208be7537753_HPS_7)'' to type 'POINTER TO IoConfigParameter' [ERROR] crr: C0077: Unknown type: 'GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7.Io_17160064_c083_41f8_9e53_208be7537753_HPS_7' [ERROR] crr: C0046: Identifier 'GVL_Io_17160064_c083_41f8_9e53_208be7537753_HPS_7' not defined Compile complete -- 3 errors, 0 warnings I attach the project.

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Thanks for the advise, indeed, this was somewhat, what my intention was. I tried around again with EDSes and DCFs, anyway. It appears that the DCFs end up in a subfolder in the attach device dialog. Astonishingly, when attaching the DCF version I get a device in the device tree, where I can add a SoftMotion axis, whereas when I attach the device not in the subfolder, then I cannot. Further astonishingly, when looking in the CANopen parameters in supported profiles, "402" is listed in the case of the DCF variant, whereas in the EDS variant "0" is shown. Comparing EDS and DCF files I cannot guess, where the difference is coming from. I cannot tell either why I have always attached the EDS variant and apparantly never the DCF variant. As I am not in the lab right now, I cannot test if the connection actually is working. Thanks again, spiessli

I'm searching a way to print several projects to PDF, in order to correct student exercises. I'm able to open the printing dialog box using system.commands["print", "print"].execute(). But I can't find the prompt names in order to complete the printing with the dialogs Do you have any way to do that?

Post by arundara on Variable Sync Issue In Soft Plc Redundancy ^{CODESYS Forge talk (Post)}
Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.

Post by pruwetbe on Profinet IO-link master - IODD files ^{CODESYS Forge talk (Post)}
Hello, we have the same problem here. Our configuration in the following: Codesys V3.5 SP19 running on Exor Exware700Q Profinet network connected on Eth1 IOLink Master Turck TBEN-S2-4IOL version 3.5.9.0 IOLink sensors E+H & Sick (Pressure, T°) We installed the codesys IO link package and have the codesys IO Link SL licence activated (on a dongle) Our problem is the following: we got the IODD files from E+H & Sick we add the devices in the codesys device repository with success They appear in the devices tree under IODD branch We added the TBEN IOLink master under the Profinet IO . The IO link master are ok and display online. The IO-Link SL package datasheet indicate that there would be a way to scan the IOLink device from the network but we did not find any way to trigger this scan. (we expect to get this from a right click on each IO-Link Master module but the only possibility there is "Plug device") When clicking on Plug Device, we get a browse window with profinet IO modules. The IODD devices are not there so we cannot select them. But other devices for other brands are available and can be plugged. Our question are : 1) how do we update the Profinet IO Module catalogue in order to be able to plug the E+H & Sick Sensors that we have to work with? 2) how do we activate the Scan IOLlink device that is supposed to be included in the Codesys IO-link package? 3) where can we find the manual explaining how to use this package?

Post by ojz0r on Assignment Efficiency - Repetitive Assignment vs IF statement ^{CODESYS Forge talk (Post)}
Its important that you know the difference between the two. Example 1: Coils[0] := Coils[0] OR (Buttons[0] AND Sensors[0] > 6); In this case the statements will be evaluated every scan and result in either true or false for Coils[0]. Example 2: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; END_IF In this example Coils[0] will latch the result in a true evaluation, if you want it to behave the same way as example 1 then you need to do it like example 3 below: IF NOT Coils[0] AND Buttons[0] AND (Sensors[0] > 6) THEN Coils[0] := TRUE; ELSE Coils[0] := FALSE; END_IF However back to the real question. There is no problem using either example 1 or example 3, if im not requiring a latch i usually go with example 1 as it is more compact.
