Hi TimH Thanks for the information, I thought that was the case so have stepped through the code and found an error that wasn't closing the port, therefore hCom was increasing. Thanks

CODESYS Forge

(Post)
Hello, Thank you for your answer. I'm afraid I was not clear on what I was trying to achieve. I'm trying to change parameters and command axes from inside a function block and the first thing that came to my mind was pass both the EtherCAT slave and axis to the function block (as image attached). But, I believe it's worse than just pass directly the EtherCAT slave address to the function block (is it???). However I was wondering if there was a way to get the EtherCAT address directly from the axis, so I don't need to pass the EtherCAT slave nor the EtherCAT address to the function block. Thank you again!

I have to enter the owner password from time to time, even though I haven't closed the project yet. Is there a way to disable this option? So I only have to enter it once when I log in to the project, and that's it.

Hi mate, With this snippet i was able to see the lastusage variable count, but it would not iterate between clients? i was only able to access the data of the target visu. it threw an error with the array of pointers stating it was not able to convert etc. also when i tried it with the while loop it created an endless loop and crashed the program. any ideas? Thankyou

The only weird situation i remeber with particular or complete frozen target visu was after the rtc clock was fallen or set back to the past. It looked like after running a while the alarm history database crashed during writing entries at a date lot of years in the past. After setting the rtc clock to actual date/time and deleting the alarm db every thing worked fine. I don't know, if this is/was a problem of our PLC hardware/firmware? Maybe check date/time at your system?

(dhumphries) I followed your advice and tried it on Ubuntu Server. Was a good choice. Your material was also very helpful :). Thanks for Your help! I no longer have problems connecting to Ubuntu. However, I still cannot install Virtual PLC. I'm currently getting a missing path message: "C:\Program Files\CODESYS 3.5.19.60\CODESYS\CODESYS Virtual Control for Linux SL\Delivery\virtuallinux\VirtualControlAPI.py." It looks as the package: "CODESYS Virtual Control for Linux SL" was not installed. But, there isn't one in CODESYS Store or I'm doing something incorrectly.

Hello Vincent, I don't have 75 channels but it works for me as described above without any problems. There is also a parameter MAX_MODBUS_CHANNELS in the library parameters for the IoDrvModbusTCP module. The default value there is 100. Perhaps you are reaching the limit there? The value can be adjusted accordingly. I assume that this value is not accepted in the input dialogue and therefore the 'fixed' limit value 10 is used.

I want to cancel the automatic address allocation for all IO mappings. If I directly set the automatic_iec_address in class ScriptIoMapping to False, the address becomes None. So I reset manual_iec_address with itselfs value. It only work with the Input IOMapping . For output, it reports an error: "Invalid address: The channel type 'Output' requires address type '%Q'." I checked the description file ,both accessRight are total same. Does anyone know what causes this?
