Hallo! Have some any idea to transfer whole GVL to Shared Memory? I also shared REATIN memory to shraed meory for making a Retain Backup System without USP in Linux on a FRAM. For an other Application we want to shared the whole GVL off obne part (e.g. GVL_Test). How cvan I get easy the Size and the Address for meory copy?

Post by trusty-squire on CNC - How to manipulate SMC_GeoInfo objects ^{CODESYS Forge talk (Post)}
Sometimes you just need to pose a question on a forum and re-read it to get clarity. pGeoInfo := SMC_GetObj(poq:=ADR(fbCncInterpreter.poqDataOut), n:=1); This won't work, I'm providing a pointer to a pointer, as poqDataOut is already a pointer! I just need to remove the ADR() and it works. pGeoInfo := SMC_GetObj(poq:=fbCncInterpreter.poqDataOut, n:=1);

Post by timvh on Profinet fault with codesys control V3 - Receive packet error ^{CODESYS Forge talk (Post)}
Are you using the Control Win SL (installed together with the development environment of CODESYS)? If yes, you might want to consider using the CODESYS RTE instead. This has real-time capabilities (running on separate core(s)). But to be able to use this, you have to install the CODESYS Ethernet driver for your network interface to be able to let the RTE access the network port also in realtime. See: https://store.codesys.com/en/codesys-control-rte-sl-bundle.html https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_windows_rts_v3.html PS, I haven't tested this myself yet, but you could try to use the SetCommunicationState method of the Profinet controller to see if you can reset and start the bus communication: result := PN_Controller.SetCommunicationState(eRequestedState := DED.DEVICE_TRANSITION_STATE.START); PS, if you are located in the Netherlands or Belgium, we could also provide the license(s) for you.

Post by tvm on Timer On Vijeo ^{CODESYS Forge talk (Post)}
Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

Post by andrax on Save Recipe on Paspberry ^{CODESYS Forge talk (Post)}
Unfortunately not. The folder does not work. There are neither error messages nor any other indication that this may be due to missing rights. I have searched the entire forum and also tested the Codesys example. The simple recipe management generally does not work! The Raspi crashes with the extended recipe management from the example. I have now found another sample that works. https://forge.codesys.com/forge/talk/Engineering/thread/61c6a04b79/ Many thanks to mcodem. After some trial and error I have found out: xcreate must be called at least once at runtime. After that xload_write and xread_save work All other functions do not work. It is also possible to save to the /home/Documents folder. So it is not due to the rights. It would be nice if Codesys would check where the problem really lies.

Post by micik on Reverse bytes in an array ^{CODESYS Forge talk (Post)}
Hello, I'm getting the data in Codesys that is an array of 8 bytes. From this array, I need to foram LREAL number, however, because of different endiannes I need to reverse bytes in this array and then copy to a LREAL variable. For this I'm using a loop and it works OK. I wonder if there is a built in function to do this. I have found CAA Memory library but it has functions like reverse bytes in DWORD. But it seems it doesn't have what I need. https://content.helpme-codesys.com/en/libs/CAA%20Memory/Current/CAA_Memory/Reverse-Bit-Swap-ByteWord-order/ReverseBYTEsInDWORD.html What I need is a function to reverse bytes in an 8 byte array, or something similar.

Post by niallel on CamBuilder and first boundary position not zero ^{CODESYS Forge talk (Post)}
Hi, I've read the CamBuilder documentation and it shows to use the left boundary of the first segment as SMCB.BoundImplicit(), so that the transition is as smooth as possible. With this it sets X and Y to 0. My first slave position is not 0 (say for example it's 100), so I would set it with SMCB.Bound(0,100). My question is that when the cam goes back to the start (Periodic := TRUE) , will it blend with the last position (360, 100) if I do this? I imagine it will, but the documentation isn't clear as the information in the Periodic Cams only says to set Smooth Transition in the cam properties - but when I'm defining it with code there isn't an option for Smooth Transition to be set. Hope this makes sense? Many thanks,

Post by acc00 on Redundancy Codesys Runtime, Synchronization ^{CODESYS Forge talk (Post)}
Hi, I’m currently testing the Codesys Redundancy application with 2 Raspberry Pi, with the idea is of using in my project 2 Wago PFC200 and 1 Ethercat Master with 2 Remote IO. After I configure the redundancy, and one Pi is Active and the other is Passive, if I disconnect the Ethernet cable of the Active, the Passive become Standalone, which is good, but the problem is the following: -When I recover the Ethernet connection, both stay Standalone. They will NOT Sync until I do it manually in the Codesys environment. How to make the synchronization automatically? -If both Pi/PLC stays Standalone, who is managing the IO? (Ethercat and Serial) I have done a test with an Modbus Slave, where I am sending a counter that increase every second. And I see that when both PLC are standalone, they both keep an active connection with the Slave, and both write values. This does not seem good, since according to this in my project both PLC would try to control the IO at the same time. Note: The Codesys have an option (greyed out, not possible to select) which says “Auto Sync”. What is the purpose, and why I’m not able to select it? I'm using Codesys Control for Rapsberry Pi 64SL Runtime in my test environment (2xRaspberry Pi 4), with the idea of using Codesys Control PFC 200 Runtime in my project (2xWago PFC200 and 1 Ethercat Master with 2x Wago 750-354 Ethercat Fieldbus Coupler). Using the last Codesys 3.5 version (SP19 PAtch 5). I'd appreciate a lot any help on this questions!

Goodmorning, I would need to set a control station that can manage a PLC network. In short I need to access to all visu programmed in any PLC of the network (LAN). I was thinking to use a PLC with buttons that call, by mean an IP address, the visu of any PLC. I don't know if it is possible but I saw that there is a RemoteVisuTarget that run CODESYS Control Win V3. Can someone suggest me how to create a remote main control station from a normal PC?

Post by viksym on Get text from textlist ^{CODESYS Forge talk (Post)}
Does anybody know how to get a specific text from a text list within a program. Obviously it works in a visualization, but because I will have an HMI that has it's own system and I will have to send variables to this HMI via an OPC UA connection, I need to be able to get a text into a string. I tried using the VisuElems like this, but it only returns an empty "" and nothing else. IF trig THEN sText := VisuElems.cmpDynamictext.DynamicTextGetDefaultText(ADR(sTextList), ADR(sAlarmID))^; //sText := VisuElems.cmpDynamictext.DynamicTextGetText(ADR(sTextList), ADR(sAlarmID))^; trig := FALSE; END_IF Any help and idea is highly appreciated because I am getting desperate here.
