Post by wollvieh on SP19 Runtime Zugriff auf lokales Dateisystem ^{CODESYS Forge talk (Post)}
Hallo, hier in diesem Beispiel ist $Download$ ein Platzhalter für den kompletten Pfad /home/pi/Downloads/ auf dem Zielsystem, wo die SoftPlc läuft. In der SoftPlc gibt man dann als Dateipfad und Dateiname wie folgt an : '$$Download$$/Datei.txt' Die Datei Datei.txt wird dann auf dem Zielsystem unter /home/pi/Downloads/ angelegt. Pfade darunter werden auch angelegt, z.Bsp.: '$$Download$$/Ordner1/Datei.txt' Beispiel des Platzhalters: [SysFile] PlaceholderFilePath.2=/home/pi/Downloads/, $Download$

What do you think about having an AI Agent specialized in ST programming in Codesys? I see this saving hours and hours of work for those who program on a daily basis.

Hello, I’m encountering the same issue. I only receive these errors when downloading to the PLC—there are no errors during the build—after upgrading to CODESYS 3.5.21.10. Is there any known fix or recommended solution? Visualization seems running ok, no PLC log error. Visualization: Error: The element of type 'VisuFbLabel' could not be updated.

Post by gland on Open project automatic with correct version ^{CODESYS Forge talk (Post)}
Goodmorning, The projects we have made (with several persons) are in differents versions, Codesys V3.5 sp18 patch4, V3.5 sp19 patch 2, V3,5 sp19 patch 5 etc V3.5 sp21 patch 3 etc.. Now when we're opening an project thats's not opend before on my pc and we're not sure in witch version it's made it's quite annoying. We don't want to update to the newest version. Is there a way that it's automatic opening the correct version? Is there a program/tool/easy way to do this? Thanks,

Post by fleaplc on CPU + EtherCAT redundancy ^{CODESYS Forge talk (Post)}
Hi all, for a new project I'm looking for a redundant controller with EtherCAT fieldbus I/O. Actually I'm using Beckhoff and it works great! but there's not a solid redundancy yet... Does someone get experience for industrial application (not raspberry) for a redundant Codesys system? If yes please share some info (CPU / OS type, bus, number of managed I/O,... and especially feeling feedback (stability, bugs, performance)... Every suggestion is kindly appreciated!! Fabrizio

Did you check the communication with a sniffer ? (ex. Wireshark) to check if the holding get to zero by a wrong writing (client initialization?) o something else?

Post by mattkaree on Mapping values with etherCAT mailbox communication ^{CODESYS Forge talk (Post)}
I am using a WAGO PFC200 PLC as an etherCAT master and a Keyence IV3-G120 with DL-EC1A attached as an etherCAT slave. I am using CODESYS V3.5 SP21 Patch 3. I was able to set up mailbox communication and can see values changing accordingly, but I want to know how I can map these values and reference them in my program. I am able to map the process data objects in the 'EtherCAT I/O Mapping' tab, but there is no where to map the mailbox values in the 'CoE Online' tab. Is there a way I can reference one of these values in my code?

Post by pernockham on Gateway in China - "Gateway not connected" ^{CODESYS Forge talk (Post)}
I think I understand my problem. They are most probably related to configuration of the network. When I use DHCP for the unit to my router it all works. However when using static IP I have not managed to reach functioning state. Trying to replicate the situation on my desk. Having a static IP on the "debian host" and a connection to my computer which then routes traffic on to internet. I have entered settings for gateway and netmask. I can ping from my "debian plc host" to internet and also do "curl google.com" so traffic seems to find its way through and back, still "Automation server" will not find the gateway. Any hints how a manual configuration should be done? Is it possibly a "firewall" issue of my "normal router"? Thanks for any help! Per
