Post by jeffg on ERROR: GetNetLinkSockAndInfoByMac(): could not open netlink socket: Too many open files ^{CODESYS Forge talk (Post)}
I just installed codesys runtime on a raspberry pi Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz (Compute Module 4) I am running on Codesys control for raspberry pi 64 SL ver 4.13.0 and I keep getting a crash after about five to ten minutes. This program was running fine on a 32bit system with runtime 4.8 previously but they upgraded the panel PC cause it got smashed. Looking at the logs I see this error "ERROR: GetNetLinkSockAndInfoByMac(): could not open netlink socket: Too many open files" at the time of crash. I do have a UDP socket open for a serial to ethernet adapter and im wondering if maybe its opening a bunch of sockets and while receiving messages, Im not sending anything to the device only receiving. Below is the code used for the UDP VAR // Scale Comm fbPeerServer : NBS.UDP_Peer; ipAddress : NBS.IPv4Address; fbReceive : NBS.UDP_Receive; xPeerActiv : BOOL := TRUE; abyReceive : ARRAY [0..255] OF BYTE; sLastValidReceive : STRING(255); udiIndex : UDINT; END_VAR IF xPeerActiv AND NOT fbPeerServer.xBusy THEN ipAddress.SetInitialValue(ipAddress := gvlSettings.sIPAddres); fbPeerServer(xEnable := TRUE, itfIPAddress := ipAddress, uiPort := gvlSettings.uiPort); END_IF fbPeerServer(); fbReceive(xEnable := fbPeerServer.xBusy, itfPeer := fbPeerServer, pData := ADR(abyReceive), udiSize := SIZEOF(abyReceive)); IF fbReceive.udiCount > 0 THEN IF fbReceive.udiCount < SIZEOF(sLastValidReceive) THEN SysMem.SysMemCpy(pDest := ADR(sLastValidReceive), pSrc := ADR(abyReceive), udiCount := fbReceive.udiCount); // Set End of String sLastValidReceive[fbReceive.udiCount] := 0; END_IF END_IF If anyone as seen this I could really use some help figuring it out. I included the Log report

Post by garmusd on Raspberry Pi 5 GPIO not working. ^{CODESYS Forge talk (Post)}
Hi, Codesyscontrol 4.13.0.0 Raspberry Pi5 64bit with latest updates. Cant get working GPIO - no output and no input. SPI/I2C not tested. GPIOs B+/Pi2, Input/Output is set in the parameters, assigned variables int the Mapping. Absolutely no reaction. Do I need to configure anything else to make it work? Thanks!

Post by timvh on FB string and naming ^{CODESYS Forge talk (Post)}
Really not clear what you are trying to do, but isn't a Struct enough? So add an object of the type DUT to the Application. Then create a structure TYPE ST_Sensor : STRUCT sName : STRING; uiNumber : UINT; END_STRUCT END_TYPE Then in you application add an instance of this Structure stSensor1 : ST_Sensor := (sName := 'my sensor', uiNumber := 1); or use it like this stSensor1.sName := 'my sensor';

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello jacobwago, I believe that the limit is fixed in the editor, but not in the driver package. There seems to be no link between the driver setting and the editor. Otherwise, I don't know why the input (>10) is blocked, but the function is available. Unfortunately, I cannot offer you any other solution apart from the one mentioned above. Kind regards

Post by davidmic on What is this ST syntax? ^{CODESYS Forge talk (Post)}
I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

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.

Post by dekelec on TrueType font problem ^{CODESYS Forge talk (Post)}
Initially I had the same problem in CoDeSys when selecting a newly installed TTF font, while CoDeSys was running. I solved it by closing Codesys and running it again to restart the initialization process. After that, using the new font did not pop up errors. I also had cases with files that had a ttf extension, but were actually not TrueType.

I am having the exact same issue and was wondering if you ever found the problem? The sample program does exactly what it's supposed to with filtering but when I implement it the exact same way in my program, the alarm list just goes blank when I attempt to apply a filter.

After many tests i see that problem comes when serial communication established for modbus rtu. If the slave device not connected we don't see the exception. If the slave device connected at serial port then we have exception about 1 hour after startup and every 10 or 15 minutes. Any suggestion?

okay, the weird thing is the driver is only continuous running when i enable debug output. if debug is not enabled it's continuous switching from running to not running. i will check again and download the libraries Which versions of libraries do you use, can you send a screenshot?

If you are really happy with PLCnext engineer, then just use that. There is probably also something in CODESYS that cannot be done in PLCnext engineer. But if you are forced to make something like this in CODESYS, then maybe just use CFC instead of FBD.

Hi, I updated codesys IDE to the newest version, but I lost the "professional developer edition" in the process. It still works fine on the older version I have been using previously. Do you know what the easiest process for getting the same integration in the newer version? It is only the GIT integration that I really miss.

At the top of the Visualisation Properties View, you can enable the "Advanced" options. This will give you access to more properties than what you currently see. There might be a variable linked to the "advanced" colour property where the fill colour is determined by the value of this variable (dword).

Hi Gustavo, can you reduce the problem to a project that reproduces the issue without the real servo drives? (You could set the servo drives to virtual and strip away as much as possible from the application.) If you can attach a project, we will have a look. Best regards, Georg
