Post by spice on WebVisu Recipe Save/Load ^{CODESYS Forge talk (Post)}
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 gatto on Modbus tcp - channel ^{CODESYS Forge talk (Post)}
Hi can you give more details? Are you talking about a danfoss? wich model? Can post the configuration of channel' I used, on the past, serial modbus with danfoss fc280 I remember ((id x 10)-1) I remember that you couldn't use continuous reading/writing of the directors but you had to use them one at a time. it seemed that reading empty registers (caused by x10) was not accepted by danfoss. So I had created a scan that used just one register, then the next etc etc with a timed interval. But this was for the serial, I don't know if it's the same thing with ethernet. I currently use Ethernet TCP/IP interface with FC280.

Post by timvh on EXCEPTION [watchdog] how to find position cause ^{CODESYS Forge talk (Post)}
Monitor what your current cycle time is (in the Task Configuration when you are online). If this is sometimes close to 200ms, then change your code (e.g. limit the loops, or prevent copying a lot of data between objects). Or just set the Watchdog time (or sensitivity) higher if you don't care that it sometimes takes longer than 200ms. If you want to find out which objects in your application consume the most time, then buy a PDE (Professional Developer Edition) license. With this you get a license for the Profiler. This can help you a lot to find the root cause, because it will create a nice overview of all objects, their calls and the time (percentage) it takes to execute it.

Post by konstantin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
Hello, basically the i950 drive support CiA402 Basic and CiA402 Advanced modes. I attached pictures of both mode supported functions. It also support CSP, VL, CSV and CST modes. It seems the homing mode is in CiA402 Advanced mode but how can you not have the homing mode in both modes? It is a vital part of any servo system. If I use the SoftMotion standard demo mode, I can move the servo absolute and relative but cannot home it. But in SoftMotion Light mode, I cannot execute any motion function. Here is the official manual for i950 servo drive - i950 Documentation Best Regards Konstantin Kolev

Post by s1ack on Wago PFC200 Ethernet / IoDrvEthernet Issue? ^{CODESYS Forge talk (Post)}
CODESYS Control for PFC200 4.13.00 CODESYS IIoT Libraries SL 1.11.0.0 Application Based License: CODESYS Control Standard M I have (2) projects with similar code base and both using Wago PFC200. On the second project I am seeing 2 things that I have not been able to resolve: 1) Errors in the log under the Ethernet Item: IoDrvEthernet: [PCI\E1Q51CE62] Could not be found on target! Please check the Ethernet settings. 2) Exception for CPU Load. "Processorload watchdog: plcload=100, maxplcload=95" I have slowed down cyclic tasks on this project, even though on the first project there is actually more code - and it does not exhibit this behavior. In looking at the CPU loading via Linux 'TOP' command there appears to be 20% idle. So plenty of headroom (my opinion). In an effort to troubleshoot I have duplicated the target hardware on my bench. It ran overnight without a CPU load exception. On the test system, I have tried (3) version of the ethernet device. 3.5.16.0 3.5.17.0 and 4.2.0.0 Presently the log does not show the error, but status says the module reports an error. I really do not know if this issue is related to the CPU load exception. The issue does not appear to effect ethernet communications (ModbusTCP or SNMP or Webvisu or PuTTy into Linux Shell). On my test bench I have ModbusTCP slave simulators for all ModbusTCP slaves, but only (1) of the (5) SNMP devices present.

Post by cer-wa on Not able to connect multiple profinet encoder in codesys Linux ARM64 ^{CODESYS Forge talk (Post)}
Hello, currently im working with a RevPi connect 5 on a codesys project. Up until now I was having a blast because things were going really smooth but for like almost a day im kind of stuck on the integration of multiple profinet sensors into my project. This is kind of a bummer because that should be an easy thing to do. What I tried so far was to create and additional ethernet adapter where I then tried to connect my devices. in the beginning I tried to connect the devices directly which was not working because I could assign the IP-adress only to the ethernet adapter and not to the devices but the device was found in the device repository (this gets important in the second part) So what I tried next was to setup a PN-Controller and connect my devices subsequently to the Controller. Sadly now the devices wont show up in the device repository anymore. To me its not clear why this is happening. And the worst thing is: I went ahead and setup a device completely like I would want to have it in the project and when I then click on scan devices I can even find the device. But it can not be added to project for whatever reason eventhough im 100% certain that the gsdml file is the correct one. Can anyone help me with this. Like I said this seems like an easy thing to do and its taking me way longer than expected already. The only thing that came to my mind why this might not work is because I have codesys license which only allows one profinet instance. Could that be the case? The error message seems then pretty unfit but ok. I will be grateful for every advice. Thanks in advance! Best regards!

Post by tk096 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work). In general: - Motion function blocks have to be called until they report 'Done', 'Error', 'CommandAborted' or a subsequent motion FB with BufferMode=Aborting is started in the current cycle. - Setting the Execute input to FALSE will not abort any ongoing motion of the motion function block. For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. I think the error SMC_FB_WASNT_CALLED_DURING_MOTION is only a follow-up (and misleading) error that results from the axis not being in operational state anymore (bus problems). Is there an error 'regulator or start not set' in the device log before the error 'motion generating FB wasn't called for at least one cycle'? Which error does the respective function block (Halt.ErrorId) report?

Post by yannickasselin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
I don't have time to go through the whole manual but as I said earlier, the servo drive does not support any of the modes needed for SoftMotion Light to work. If you want to use the full SoftMotion, you could use SMC_Homing function block to do the homing. This function block does not use the Homing Mode. It still uses the CSP mode and does the logic in Codesys runtime instead of in the servo drive. Read the documentation about it to see if it fits your needs. But if your controller only supports SoftMotion Light, I am afraid you will not be able to use the i950. I do a lot of motion stuff with different servo brands. Some support all the modes needed for SoftMotion Light and some don't. You really need to make sure the modes are supported before choosing a brand over another. I tend not to use brand specific controllers in order not to be limited by their supported features. I usually choose a PC (Linux or Windows) and install the Codesys runtime and licences myself. This is the most flexible way to use Codesys in my opinion. Depending on how many axes are needed in your project, a full SoftMotion license may not be more expensive than SoftMotion Light because SoftMotion is available as Application based license whereas SoftMotion Light is not. But of course, SoftMotion is harder on the CPU than SoftMotion Light.

Probably the enum from the library doesn't have text support. In that case you need to add your own TextList to the application. In the rectangle you should use the property "dynamic text" to link this object to the textlist which you have created yourself and then link the text index to your enum variable.

Not sure, but maybe before you enter step 5, set i, lineindex and charIndex to 0. And the buffer variable should have a size bigger than 1 line. Additionally I think you should set bufferstart to 0 before you enter step 5. And in the OSCAT function you always point to the buffer address, but shouldn't this be (buffer + bufferstart)?
