Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The new (UTF8) string library is faster and can handle large strings. https://content.helpme-codesys.com/en/CODESYS%20String%20Libraries/_strlib_start_page.html PS, in CODESYS, the maximum string length is not 255 characters. The String functions of the standard library are limited to strings of 255 characters. But you can use other (memory) functions to handle strings larger than 255 characters.

I've also noticed that when I turn off "enp1s0", suddenly the source IP for the ModbusTCP changes to that of "enp2s0", which is what makes sense to me. When I turn it back on, the source IP remains that of "enp2s0".

Post by fajean on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
We are having issues right now, and I just stumbled on that post. It seems to me you are saying your Linux ARM control is RPi 5-compatible, but the one you sell specifically for RPi is not. The fix you are proposing requires customers to re-purchase a CODESYS licence. Is there a time frame for that to be fixed?

Hi! I tried to start Codesys V3.5 SP11 program and this error message popped up (see attachment). Program worked fine last week. I tried to uninstall and then reinstall the program but it did not help. If I choose Ignore or Retry options the program works expect the UI is missing. Any ideas how to fix this?

Post by micik on SysFileOpen not working ^{CODESYS Forge talk (Post)}
Hi, I have the same problem. Some of the libraries I created over time depend on writing files to a folders like c:\Temp. I can confirm that proposed solution is not working with 3.5.20 Patch 2. Can you please specify wich exactly .cfg file needs to be modified and in what way, in order to include c:\Temp in the SysFile path? Thank you!

Post by kevinrn on Signing Packages without exposing the password of the certificate ^{CODESYS Forge talk (Post)}
Indeed, I'm also seeking a solution for this issue. The main challenge we face is the requirement to use EV (Extended Validation) Certificates. Due to security considerations, it's not possible—nor is it ever recommended in such cases—to export the certificate with its private key.

Post by lukebouchard on IFM-Sensor ADC READ ^{CODESYS Forge talk (Post)}
Get a different sensor that is 0-10V and 0-350 Bar. There is nothing you can reasonably do to boost the range of the sensor, and the PLC will only ever be 0-10V. Take away is to always be careful to match the sensor and PLC input ranges in the future.

Hi all, in the online help it written, that array of reference to data type is not possible. Ok... but if I create array of struct of reference to - everything works fine - please see the screenshots: and it works this way OK. Is it intention or error in compiler 3.5.18.20 and we should avoid it? Thanks a lot, Jan.

Post by davidbo on Modbus: Is there a way to get the channel index from the channel name? ^{CODESYS Forge talk (Post)}
When I use the FUNCTION_BLOCK ModbusChannel I have to sepcify the integer iChannelIndex It can easily go wrong if one has many channels. It would be better if one could use the name. Is that possible? Attached a snippet of the channel name and the channel index to the left.

Hi if you add in (ttyAMA0 should fit to your HAT's device [SysCom] Linux.Devicefile.1=/dev/ttyAMA0 to /etc/CODESYSControl_Usr.cfg since 4.12.0.0 version /etc/codesyscontrol/CODESYSControl_Usr.cfg then access in CODESYS with Com1 should do it. Keep in mind that only adapters work (for RS485) which do determine the send/receive direction in hardware

Post by yannickasselin on MQTT QoS 1 & 2 ^{CODESYS Forge talk (Post)}
Hello, After some more tests, here is what I found out. It seems we have to increase the uiKeepAlive and tPingInterval parameters. If I increase the uiKeepAlive value to 60s and the tPingInterval to 30s, then if I disconnect the ethernet cable from Codesys and publish some messages to which Codesys subscribes to and then reconnect within 30s, I will get the messages. If I don't reconnect the cable within 30s (ping interval), the client goes in error with "ACKNOWLEDGE_TIMEOUT". When this happens, it will not automatically reconnect after reconnecting the cable. I have to disable and re-enable the client but I will not get the published messages. I need to do more tests because there are a lot of weird things happening when playing with the ping interval and the keep alive. It is not clear to me what does what. I even ended up not receiving messages anymore, even if I disabled and re-enabled the mqtt client. The client did not give any error. The only way I was able to get messages again was by modifying my client ID. After that, if I try to re-use one of the old client IDs, nothing works (publish, subscribe) and I get a TCP_INIT_ERROR and sometimes a TCP_READ_ERROR. I need more explanation/documentation about these weird behaviors. Maybe it is the way I use it, maybe it is related to the broker (I am using Mosquitto with default parameters). When using a Node-Red client, everything works perfectly. I am trying to achieve the same behavior with Codesys but it seems impossible so far.

Is it possible under CODESYS V3.5 SP18, to connect a split (german Leitungsverzweigung) with an existing block (e.g. AND-module)? Or to connect the output of an existing block to the input of an existing block (e.g. OR-block)? Any ideas? P.S.: Sorry for the german title, I do not know how modify the title.

Update the Device: Right-click on the device icon in the project tree. Select the “Update Device” option. Recompile the Project: After updating the device, recompile the project from scratch to ensure that all changes are included. Check Task Settings: Go to the “Tasks” tab in the project. Check the priority settings for the tasks to ensure they are configured correctly.

Post by tyronnosaurus on SysLibMem.lib Where To Download? ^{CODESYS Forge talk (Post)}
It should come by default on a normal install of Codesys 2.3, but it's a bit hidden: Like for any other library, go to Resources > library Manager > Right click on list of libraries > Additional library. On the browser that opens, instead of looking in the default folder, use the dropdown menu at the bottom to change the folder (SysLibMem should be on the 3rd folder).

Hello, I hv a problem. Couldn't solve this for 2 days now. So I'm quite new at CodeSys and I have to use the spi port x30 on the edgelogix rpi 1000. So what I have to do is just 'add device' at the SPI where I hv to pick the 'SPI master' after that I hv to change the parameters according to the edgelogix I did found in the spidev.h but nothing got updated so I 'add device' again where I pick the PiFace I/O Driver and I put my variables at the I/O Mapping, which i put the input startbit at the in part and led at the out part. I want to make the led blink according to my structured text code but somehow the hardware didn't connected with the CodeSys spi port. Nothing happens. Any idea what I have to do?

Post by shooxplc on How to call the same program from library and get the vars updated. ^{CODESYS Forge talk (Post)}
Hi, I am writing to you today because I would like to create a library that would contain a program with its various subprograms, in my example "PLC_PRG" with "a", "aa", "aaa". But once the library is created as shown below: I would like to be able to drag and drop my folder as many times as I want (let's say I manage the same system multiple times). Once the drag and drop is done, we can see the second folder with the variables renamed successfully. As shown below: But my variables in CAD_1 remain the same as for CAD, so it's PLC_PRG instead of PLC_PRG_1, for example. Is there a solution to automate this? I wouldn't want to have to rename all my variables manually, considering that in the program where I want to do this, the number of variables is substantial. Lucas.
