Post by dhumphries on How to determine code size ^{CODESYS Forge talk (Post)}
I'm trying to determine which Codesys Control license I need, the Control Standard S has all the features I think I'll need, but the code size is limited to 3mb, I created a simple program with only 1 line of ladder logic and a simple visualization with a button and an indicator. When I generate code I get some messages, one indicates that the total allocated memory size for code and data is 2.1mb. Is this metric the correct size of the code? I question the size because it exceeds the allowable code size for the Basic S and Basic M licenses and consumes 2/3 of the available memory for the Basic L or Standard S license. What tool can I use to estimate the size of code as it relates to the runtime license limit?

use Arm64 SL or Arm SL instead of the PI package - this will work

16.4 Epis What has it to do with the manufacture? It just a licence more not. So basicly the idee of codesys sucks. 3s acts like its posible to add a license. And then it depence on the manufacturer. Why ?? Its a computer !! has nothing to do with the manufacturer. Most dont what a basic licence because they have to pay for that. 3s is the problem not the manufacture of the hardware. Its like the licence of the raspberry pi. HMI is not working. Sorry you get a refund. Why suggest that its possible wen its not !!. It cost me a lot of time. Who pays my time. Why do i have to pay for somting thats not working.

Post by k2saki on CNC / G-Code streaming processing ( to start quickly in long G-Code File ) ^{CODESYS Forge talk (Post)}
Is it possible like G-Code streaming processing (like FANUC or SIEMENS DNC Function )? Or Does anyone know the tips for CODESYS Motion to start moving long Long G-Code File quickly? I have to wait long time after "Start" button to start moving, I have to wait finishing interpreting whole G-Code file, ( and I have to prepare huge buffer to store. ) Now, I'm working on my CNC Project using SMC_ReadNCFile2, and SMC_NcInterpreter to preprocess G-Code. I tried to set SMC_Interpolator.xExecute to true to Start while after SMC_NcInterpreter processed more 50-line of G-Code, but that not worked, I had to wait SMC_NcInterpreter processed all lines to start SMC_Interpolator. G-Code have about 2000 lines of XY of G01 (or more over.. ) of short segment that a CAM software has exploded from NURBS Curve.

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
I have a version of codesys 3.5.16 on my local machine and a vm. The local machine has loads of codesys versions and libraries installed etc. I can open the FPosCR_Example_Project_SP16_patch1 project on my vm without any errors. On the local machine I get the error C0077: unknown type IoDrvEthercatLib.ETC_CO_SdoWrite. I can, on the local machine, declare a var of type IoDrvEthercatLib.ETC_CO_SdoWrite and include it in the code without adding an extra error. The problem only seems to affect the library. This is seems more an issue with my codesys set up rather than something with festo. I would like to know the possible causes. I understand most of the library manager features but it's not clear how to find the cause. Thanks

Post by imdatatas on Unrecoverable SoftMotion state after switch to PreOp ^{CODESYS Forge talk (Post)}
Dear @alimans, Additionally, As far as I know since starting from Softmotion V4.18.0.0 automatic restart behaviour for an axis has been changed for this issue. See below explanation from release notes. "With CODESYS SoftMotion 4.18.0.0, the behavior of SoftMotion axes after a loss of communication to the servo drive has changed. Now, an automatic reinitialization is performed as soon as the communication is established again. Before, an explicit call to SMC3_ReinitDrive had to be performed. An example for a loss of communication is that the cable to one of the drives is unplugged." Regards, imdatatas

Post by dantheman on Connecting to SoftPLC Only Works By Turning Off Modbus Ethernet Port ^{CODESYS Forge talk (Post)}
I have an IPC with 2 ethernet ports and 1 Wi-Fi. I'm using ModbusTCP with the ethernet port named "enp2s0" connected to my remote I/O. This works fine when testing with Python and also works with CODESYS, but CODESYS is only able to scan for the Linux SoftPLC when I turn off the "enp2s0" interface. In other words, I can't get online with the IDE if I want my ModbusTCP comms to run with CODESYS. I'm using a Linux SoftPLC that has the following entry in CODESYSControl.cfg, hoping that this will allow me to connect with "enp1s0" or "wlp3s0", and leave "enp2s0" for field comms, but this seems to only make the source IP of the ModbusTCP comms to be bound to "enp2s0". That last point is the case only if I don't restart the service, but if I do restart the service after changing the config file, the source IP for the ModbusTCP comms then becomes the one for "enp1s0", which is very confusing to me: [SysSocket] Adapter.0.Name="enp2s0" Adapter.0.EnableSetIpAndMask=1 On the device list, I only have "enp2s0" given as the ethernet device that has the ModbusTCP master & slave beneath it, shown in Screenshot 1. On the IPC, I can ping the ModbusTCP client (remote I/O) from "enp2s0", and I've attached a Wireshark capture of running ModbusTCP from the CODESYS runtime as Screenshot 2, 3 & 4 (again, I can't get online when this is running, I have to turn off "enp2s0" to connect even when it's idle and I don't have an active TCP session with my Python tests). Like I explained above, the source IP is "enp1s0", even though the ethernet device on the project is "enp2s0". I was lucky to catch the red message that showed the source IP that makes sense to me (the one for "enp2s0"), but for some reason that connection was reset and I never saw that packet again. I've also tried this with Auto-reconnect both enabled & disabled, for the ModbusTCP Master device. I also have to turn off "enp1s0" and then turn it on, just so that I can have the ModbusTCP comms running from "enp2s0" (which is not intuitive in any way to me, I'd love some help understanding that phenomenon as well) in the weird manner that I've described above. I would be very appreciative if someone can help me figure out this pickle. I'd love to just connect to CODESYS through my Wi-Fi interface and leave my ethernet ports for field comms.

Post by fless on No source code available for profinet library ^{CODESYS Forge talk (Post)}
looks like you are running in a bug in the newest version 4.4.0 of the profinet library or the new library triggers a bug in your code. did you update your profinet device too? you could try to downgrade to an older version of the library. via library manager - placeholders, double click Profinet 4.4.0 in the library column and choose an older version.
