Post by eoahe on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hey Guys :) I have the following Problem using Modbus via Codesys: I'm trying to implement a Modbus Device into my codesys project. The device is a Router from Teltonika (RUT956) and it can communicate via Modbus. Currently I'm trying to implement it into my codesys prject as a slave and I'm using my windows computer as master. As it is not a codesys device (the codesys application is not uploaded to device as it has its own software) I'm having problems requesting and reading registers from the router. I've set up my windows computer as Master and implemented the router as slave. When I go online on my master device it sais that it has established a connection to the slave (router)(So I'm thinking this could work as there is a connection?). The goal is to read the GPS (latitude and longitude) data and on the homepage of teltonika you can find the register address and number of registers (adress 143 for latitude and 145 for longitude; both have a number of two registers). I've found tutorials how to read specific registers via their register address with other modbus programs (like modbus-cli), but as my entire project is established in codesys I was hoping to read these specific registers via codesys so that I can show the GPS data on my dashboard. I've tried establishing slave channels but that hasn't been working. I tried read input register channels of the length 4 but it's not possible to define specific register addresses to read via codesys so that didn't work (I jsut get a slaves device failure) and I've also tried establishing 516 (total number of registers the router sends I think?) read inputregister channels but that has the samle failure... So i guess the problem I'm having is establishing slave channels to read these specific registers. Does anyone know how to tackle this problem and has maybe had the same problem? Or maybe someone knows a workaround? I'm quite new to codesys so maybe I'm also lacking expertise...

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

Post by rshabsh on Using Latch Variable in Alarm as input from text list ^{CODESYS Forge talk (Post)}
I am currently utilizing Alarm Manager’s Latch Variable 1 to display additional information related to alarms. However, instead of mapping this latch variable to a fixed PLC variable, I would like to dynamically update its text content based on the selected language in the system. To achieve this, I am considering using a text list that corresponds to different languages rather than directly linking Latch Variable 1 to a PLC variable. This approach would allow the displayed alarm information to be automatically translated according to the active language setting. Could you please confirm if this method is feasible within the Alarm Manager configuration? Additionally, if there are specific steps or best practices to follow when implementing this functionality, I would appreciate any guidance you can provide. Looking forward to your insights.

Post by imdatatas on 3.5 P20 hangs - no response ^{CODESYS Forge talk (Post)}
Hi, You can give a try it by adding "Codesys.exe" in the "Exclusions > Process" section of the Windows Security Center or your antivirus program. I hope it works for your situation. Antivirus programs check many things during both the installation or startup of an application, and may be slow down or block some functions. Regards Imdat

Post by kumareasu on Persistent variable storage ^{CODESYS Forge talk (Post)}
Is there any function function block which can store the persistent variable in HDD/SSD immediatley. My observation is that the persistent variable is getting stored when we shut down or restart the system (Windows+ CoDeSys RTE SL ). the persistent variables are not stored in HDD/SSD, if I power off the system without proper shutdown. Seeking your feedback.

Post by dhumphries on Minimum system requirements for codesys control standard S ^{CODESYS Forge talk (Post)}
I'm working on a low cost project and I'm considering installing the Codesys runtime on a PC running Linux Debian instead of buying a PLC with a pre-installed runtime. For my needs the Control Standard S license should be capable of running some IO over ethernet/ip, and a webvisu. The PC I am considering has a AMD GX-424CC 2.4GHz processor (4 core/4 thread) and 4GB RAM. This may compare to a raspberry pi4, but I know an X86 processor doesn't directly compare to an ARM processor, and a processor can have a high clock speed but other factors like L2/L3 cache can influence the overall performance. I can't find any published specs for the processor and RAM requirements to run the Codesys Control runtime, does anybody have a link to the minimum system requirements or experience using devices that are at or below the minimum system requirements. A raspberry pi with the control for raspberry pi SL runtime license would be the lowest cost option, but the license is not for commerical use. This restriction is somewhat vague, can anybody clarify if this means I can use a raspberry Pi runtime for in-house automation, what about if I am selling an integrated system that uses a raspberry Pi as a controller?
