Post by fless on Warning C0564 when compiling CNC project with variables program ^{CODESYS Forge talk (Post)}
Hello, we are porting a CNC project from codesys 3.5.16 to codesys 3.5.19. The project has lots of CNC programs with variables. now we get hundreds of messages like this. [WARNING] CNC Test SP19: TestCNC SPS: PLC Logic: Application: C0564: A reference to uninitialized variable varCNC is used for initialization of TestCNC_D. Accessing the uninitialized variable may result in unexpected behavior. The objects program_name_D are implicit generated by codesys. I see no way to generated them after the variables. Is there a way to correct the initialization order? We know how to suppress this warning. But we need a clean solution as the warning already saved us in a other nonCNC project. Attached a small demo of the problem.

Your function block instance is not called, so the code is not executed to set the light on when the button is pressed.

Post by timvh on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
I'm not sure what you are trying to do, but getting the CurrentUserGroupID like this will not work, because there could be multiple Visualization Clients and each can have a different user that is logged in. Also when you go online with CODESYS and open an Visualization, this is counted as a client. Probably this is the reason you see it changing. What you can to is "iterate" over all clients and then see which user is logged in on which visualization Client. For this you need to add the Visu Utils library to the project and call the FbIterateClients. See https://content.helpme-codesys.com/en/libs/Visu%20Utils/4.4.0.0/VisuUtils/VisuActionUtilities/Function-Blocks/FbIterateClients.html fbClientIteration( xExecute := x_Execute, itfClientFilter := VU.Globals.AllClients, itfIterationCallback := fbIterator, xDone => x_Done, xBusy => x_Busy, xError => x_Error, eError => e_Error); The fbIterator, in the example above, should be an instance of an FB which you have created yourself and this must implement VU.IVisualizationClientIteration. For example: FUNCTION_BLOCK FB_ITERATOR IMPLEMENTS VU.IVisualizationClientIteration Then automatically the corresponding methods will be called. In the HandleClient Method, you will get an interface to the client(s) and then you can get the current user through this interface: itfClient.UserGroupId You can also get the UserName: itfClient.UserName

Post by garyl on Comments in arrays and assigning RST coil's to 600 outputs ^{CODESYS Forge talk (Post)}
Hello all, im working on a project that requires me to convert an old automation direct DirectSoft PLC d2-250-1. One of the problems im encountering is that all of the comments are attached to members of the different addresses. When i convert the addresses (1777 "C" registers, 777 X registers, and 20,0000 V registers) im running into difficulties keeping the inputs/outputs correct since they are missing documentation. Is there a good way to retain the comments of the indexes in the array? Secondly, initially i was declaring the "C" and "V" addresses individually and this worked to retain the comments as to which register did what, however i ran into a problem when one rung reset (or set to 0) approximately 600 C Addresses. Since each tag is separately declared this proved to be nearly impossible without a literal wall of code that attempted to crash the program. So i converted all of the registers (C,X,Y,V) into separate structs, declared them as arrays and pointed all of the original call outs in the program to the newly defined structs. However i have now lost comments and the program is very hard to follow. Thanks for any help with this issue.

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.

Post by comingback4u on Memory Address Overlap ^{CODESYS Forge talk (Post)}
Hello, We use a controller that comes with a bunch of predefined faults. These faults are considered active and historic. They are a 32 byte array but only take up 26 bytes of data. Because of this the historic faults start at address 26 instead of 31. Active faults variable take up address location 0 to 31. Historic faults variable take up address location 26 to 57. Because of this overlap I get an error that these overlap and it wont allow me to download to my controller. This isn't an issue in 3.5.5.4 but becomes an issue in newer version. Is there a way to turn this off? If I change the address location, the historic faults then become broken without doing some manipulation in the code. The software will build just fine. Thank you for your time.

Post by duvanmoreno24 on Modbus writing on value change ^{CODESYS Forge talk (Post)}
Hi all, I want to know if someone has an idea of how I can write on value change in Modbus Codesys. I have a Wago PLC and I was used to work with E-cockpit which it was quite easy to do that without the necessity to trigger any value when there was a change in the variable ( I will put how easy is ). how you can see just changing the trigger in "On value Change" will do that channel writing automatically when It detects a change in those arrays. On the other hand, in Codesys if I enable the rising edge in Codesys It ask me to put a bool variable and if triggers is going to write that value. That is making me that I have to create a function or a logic to detect the change, the problem I have is that doing that is very tedious. I first approach I got it was to create a Function who returns a bool when the value change, but I tried to keep the old value but what is happening is that in Functions all the data is erased every cycle so I can not keep any Old value. so in the Main program the trigger is going to be TRUE all the time due, the old value is cero every cycle. The second approach I got it was using a function Block (POU_1) and it works but I dont want to instance that function for every Channel or value that I want to check if the value change, Basically if I have 200 values to write trhough modbus I have to create 200 instances of that function which I think it is not practicall at all. It should be a better way to implement this as e-Cockpit from Wago Does. However, I haven't been able to know how.

Post by wb16 on Visualisation generates "Unresolved reference" ^{CODESYS Forge talk (Post)}
Hello Zol6, Have you solved this issue? I use Festo PLC CPX-E-CEC-C1 to create alarm monitoring project. In CODESYS V3.5-SP18 I used the Alarm Storage object and have the same problem. Is it the PLC that is not compatible or the version of the library is not match? Best, wb16

Post by trusty-squire on Confused by dwIpoTime input for SMC_Interpolator ^{CODESYS Forge talk (Post)}
Hi, Learning Codesys CNC, and I am confused by the dwIpoTime parameter. I have a basic demo application, using SMC_Interpolator feeding into SMC_TRAFO_Gantry2Tool2, which then sets the position of the x/y SM_Drive_Virtual axis. I also have a C axis which revolves the tool, which is controlled using a simple tangential angle calculation SMC_CalcDirectionFromVector. The GCode I'm using has feed/accel set at 500. The axis configuration limits are well above that (2000). What's strange is that, when I run the simulation, the feed speed changes drastically when I update the variable dwIpoTime. The larger the number, the faster it moves. What's going on here? The documentation only says "This variable has to be set for each call. It represents the cycle time in μsec." Why does it change the feed speed I'm seeing the in simulation? What is a good number to use? The example I was looking at set it at 5000. Screenshot attached.
