Post by miodusy on File transfer via visu and codesys automation server ^{CODESYS Forge talk (Post)}
I have a problem with the file transfer library. Namely, it does not work via the codesys server. (error 5; overtime, and visualization resets). They operate mostly in local chains. I tested different browsers and VPN from the router. It works everywhere, except through access from the codesys automation server. The client, having many machines under one account, prefers to keep it that way rather than use an individual VPN just to download a backup. Does anyone have an idea what the problem is? Sylwester M.

Post by jari-koivuluoma on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
When I create a new textlist in Codesys 3.5 SP19 Patch 5, it wont appear in the dropdown menu at Rectangle element > Dynamic texts > Text list. If I just type the name of the textlist to the field (in quotes), I get an error saying that some file is missing. Any good ideas what to do and what is going on. I recently updated to that version and I only now noticed this when I needed to add a new textlist so Im quite screwed with this not being able to add text lists. While im typing this, I tried copying an existing list and modifying it and it seems to show. Any ideas?

Post by manuknecht on Maximum dynamic limits of MC_MoveLinearAbsolute and MC_MoveLinearRelative ^{CODESYS Forge talk (Post)}
Hello all I use an axis group with two linear axes in a kinematic system. Using MC_MoveLinearAbsolute and MC_MoveLinearRelative, I am trying to realise dynamic movements (set velocity: 1 m/s, set acceleration: 30 m/s^2) with the highest possible jerk, as I want to compare this with a movement with a trapezoidal velocity profile. However, my measurements show that the axes accelerate with a maximum jerk of approx. 800 m/s^3, even if the value in the function block was set to 10,000 m/s^3. I have already increased the dynamic limits of the two axes accordingly (Velocity: 5000 u/s, Acc-/Deceleration: 250'000 u/s^2, Jerk: 100'000'000 u/s^3, where 1 u = 1 mm), but this had no effect. I have checked the input parameters of the function blocks and the VelFactor, AccFactor and JerkFactor factors are all set to the maximum (value 1). Reducing the cycle time has resulted in a higher jerk, but as we are already working with a cycle time of 1 ms, there is nothing more that can be done here. The axes themselves are still a long way from drawing the maximum current, which is why I assume that this should not be a problem either. Are there other factors or parameters that influence the dynamic limits and therefore allow faster movements? The PLC I am using is a Raspberry Pi 4 and Codesys V3.5 SP20 with all libraries up to date. Thanks in advance Manuel

Post by tk096 on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hi, under this circumstances the performance of a Raspberry Pi 4 should be sufficient to run a Softmotion robotics application. A closer look at the project would be required. Maybe you could contact the codesys support? Usually it is recommended to run the planning task cyclically every 2ms with task priority of 0 on a dedicated core. In the task configuration you can have a look at the average and maximum execution time of the planning task. You could use the function block SMC_TuneCPKernel (https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_TuneCPKernel.html) to define suitable values for the parameters 'fSyncBufferDuration' and 'fPlanningInterval'. However, as previously mentioned, the performance of a Raspberry Pi 4 with realtime patch should be sufficient. The 'fPlanningInterval' parameter specifies the maximum planning step width in seconds. The cycle time of the planning task should not permanently exceed this value. A higher value reduces the computational effort, but can lead to a violation or no full utilization of the set limit values for velocity, acceleration and jerk. From a starting value of 0.016 seconds, the value should be increased gradually until the performance is acceptable. The parameter 'fSyncBufferDuration' specifies the size (in seconds) of the buffer between the planning and fieldbus task. The cycle time of the planning task must not exceed this value at peak times (this will lead to the error SMC_CP_QUEUE_UNDERRUN). A higher value can compensate for peaks in the cycle time of the planning task. At the same time, however, this also increases the latency for executing interrupts and aborting movements.

Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)

Hello at all I'd like to know how to configure CODESYSControl_User.cfg in order to use a specific network card for OPCUA Server. In the past, I tried to ask in "Forge" about this topic, but I could find neither help nor document informations about it. Reading the file "codesyscontrol.log" I see these logs OPC UA Server Started: Hostname: NTLRPICTRL01, Port: 4840 URL: opc.tcp://NTLRPICTRL01:4840 Loopbackadapter activated. **All available networkadapters are used.** Multithreading activated. 3 workers used. My controller, which is a Linux PC, has got two network cards eth0 and eth1 I whant to use the card with name "eth0" as a server for OPCUA and keep the "eth1" free for other stuffs. Is it possible ? Best regards Rossano

Post by matthew on New Ladder Editor Issues ^{CODESYS Forge talk (Post)}
Hi There, When using the new ladder editor there is no option for function blocks to Remove uncalled FB call parameters. I also see no update function block. When you double click the function block it no longer opens the function block. I also now get warnings if I insert FB call without a contact in front. Warning is: (Impl)): C0373: Expression or part of it has no effect I take it the new editor must work differently? The only reason for using new ladder editor is the ST execute/block editing is far better, If you have alot of text in the old ST execute the editor window is very small and when online it's even worse. The new ST block seems a lot better Thanks!

I'm currently reworking the controls on a cnc press brake and wanted to load various recipes as programs to run. I'm using a 2d array of REALs to store the X and Y coordinates as well as some other program parameters in a recipe. I'd like to store all of the recipes on a computer used as the HMI that way the text files can be edited and uploaded offline. I'm using Automation Directs P2CDS-622 Can this be done through webvisu? If not would a license for Codesys HMI SL on the computer allow me to accomplish this? I've attached the Project File Thanks, Spice

Post by abrarsk on SysCom Library Usage ^{CODESYS Forge talk (Post)}
Hello all, I am facing issues with using SysCom library. With SysCom23 library things were simple but since we are migrating to 64bit systems, I am writing a Porting program. With SysCom23, opening the comport was as simple as providing the ComPort no. which returns the Handle as a DWORD. dwHandle:=SysComOpen(Port); But the new library is a bit different. It is asking for 2 input parameters to open the Com Port - Port Number and POINTER to RTS_IEC_RESULT IF hCom = 0 THEN hCom := SysComOpen(ComSettings.sPort, ADR(pResult)); How should I use the RTS_IEC_Result? I can find RTS_IEC-REUSLT under SysType2Interfaces of SysCom library. Also, can someone give me a general understanding of this RTS_IEC_REULT and RTS_IEC_HANDLE, etc.?
