no config file is ok, the feedback is: your hardware must support this send/receive switching

You need to ask Weintek if they support the licensing. For Softmotion the device should be realtime capable.

Post by madskaizer on ModbusTCP Slave Device, maximum uiClientConnections? ^{CODESYS Forge talk (Post)}
I got a Wago PFC200V2, running Codesys 3.5.16.40, 100ms scan cycle, consumes about 20ms. It will randomly crash the runtime every 10 minutes to a few hours. We suspect an overloaded ModbusTCP Slave Device, as this is work done by a 3rd party contractor, but we can not find anything in the help files or documentation, that mentions a hard limit on maximum number of clients connections. This PLC currently has 44 client connections to the Slave Device and 29 slaves configured for its own Master Device. This topic metnions a hard limit of maximum 16 connections, but where is this written? https://forge.codesys.com/forge/talk/Engineering/thread/bd95b9d6d2/

Post by sean-barton on Function block method default arguments ^{CODESYS Forge talk (Post)}
I have default arguments specified for function block methods but when calling a method, an error is produced requiring me to supply all the arguments despite there being default values. According to the online documentation, under section "Calling a Method" and subsection "argument passing" of the following link: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_obj_method.html "Passing an argument for an input ... can be omitted ... for which a default or initial value was specified in the declaration..." I have found this to be the case for all Codesys IDEs I've used, 3.5.11, 3.5.16, 3.5.17, 3.5.19. Am I missing something?

Post by danwoodlock on Rpi zero w lost license after 4.11 update ^{CODESYS Forge talk (Post)}
Hello all, Encountered an issue with my zero which seems to have happened after the 4.11 update. It now runs in demo mode (2hr) and I am trying to see what the appropriate steps are prior to contacting codesys directly. Background: I recently did a fresh install of w11 on my pc, so it seems "c:\ProgramData\CODESYS\Licenses\" only has information related to my pi5, which I licensed just this past Friday. I have all my license documentation about my rpi zero as far as the emails received, but when I try to claim using the ticket number it says its already been used, or something to that effect, which it was. Currently trying to perform device license reader, which is taking some time.

Post by laruso on Runtime device Enable/Disable procedure ^{CODESYS Forge talk (Post)}
I implemented the parts from the CAA Device Diagnosis Example.project and could use it for switching on and off, the CAN devices that were located under the CANbus and CANopen_Manager. But i can't do the same with I2C_master_test_version or devices below this one. In the example project there is only the EtherCAT Master, CANbus and CANopen_Manager, and Ethernet with devices below.

Hi, thanks a lot for the response. I did check all these parameters, but if the PlanningTask takes up to 60 ms, I can't increase the Buffer to such values. I contacted the Codesys support with a projectarchive. Let's see if they can help. Thanks again for your great support!

Post by eschwellinger on License problem gateway ^{CODESYS Forge talk (Post)}
most important information are missing: Which CODESYS Version? Which runtime version? Which plc type (manufacturere).. Not all plc manufacturer already support application based licenses. From your pictures I see you have activated 4 axis Motion (which is an applications based license type) does only work on plc's which do support this.
