Post by pascaljt on Function block for Ethernet/IP ^{CODESYS Forge talk (Post)}
Hello, I program a function for an Ethernet/IP controller. I made a structure with input and output corresponding with the map of my controller for the function block. My problem is that I don't know how to do the link between the controller and my PLC (CC 100 from Wago). The addresses declare in Codesys are illogic, The first addresses are 12 and 13 then 7 then 4. How to do corresponding the addresses of the controller and the input / output structure ? IP adress ? Does I must create the all variables of controller with the controller adresses to use with the function block ? Thanks for your help. (I hope I'm clear, I'm not english)

Post by peterned on Array to String ^{CODESYS Forge talk (Post)}
max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

Post by andrej on Creating, using an external Function. ^{CODESYS Forge talk (Post)}
Hello all, I would like to create a simple which runs directly on Control WinV3 x64 3.5.21.0 For this purpose I created a simple dll myAdder.dll in Cpp // MyAdder.cpp // cl /LD /EHsc MyAdder.cpp /Fe:MyAdder.dll #include <windows.h> extern "C" __declspec(dllexport) int __cdecl CmpMyAdder_Add(int a, int b) { return a + b; } I added the dll in the respective folder. Furthermore I "registred" the dll in the CODESYSControl.cfg. However, when I want to use the library I get the error message: Uresolved reference: *'CMPMYADDERADD' * Can you give me a hint what step I missed or where I need to declare the dll, such that the dll resp. the reference can be resolved. Many thanks and kind regards

Post by jdjennings1962 on Trouble accessing Math functions in OSCAT library ^{CODESYS Forge talk (Post)}
Hi all, I am trying to utilize the ARRAY_SDV standard deviation function, part of the Math group in the OSCAT library downloaded from the CODESYS store. My Codesys version is 3.5.19.10. When I add the OSCAT to my Library, it shows a subset of the library (Standard) as fully installed and signed (see pic). However, the Math functions are not in this Standard group. The Math functions I need can be viewed as source code in the full OSCAT_BASIC, though this the symbol next to this library suggests it is source only and not fully installed. When I try to declare an instance of the ARRAY_SDV function in a program, it is not known. I have tried reinstalling and Building . . . Any help would be greatly appreciated. Jeff

Post by alexgooi on FB_INIT in library ^{CODESYS Forge talk (Post)}
Dear Forum, I currently have a challenge. I have a library with some communication classes. These communication classes need to be linked to an interface like this: Devices_and_controllers.Comm_Frame.Modbus_GVL_Link.KNX_TCP[Interface_Index] := THIS^; This is executed via a FB_Init() method. When I try to do this in a program this works fine. But when I declare the FB_Init() in the library the FB_Init() method is being called but the link is not made (interface still has the value 0000000000). The Objects and interfaces are defined in the library (GVL), so I’m assuming the data should be there. When I call the FB_Init method explicitly in the program it also works fine. Whys is this not working when it is all defined in the library? And is it even possible to create a structure like this in Codesys? Kind regards Alex

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
I have a version of codesys 3.5.16 on my local machine and a vm. The local machine has loads of codesys versions and libraries installed etc. I can open the FPosCR_Example_Project_SP16_patch1 project on my vm without any errors. On the local machine I get the error C0077: unknown type IoDrvEthercatLib.ETC_CO_SdoWrite. I can, on the local machine, declare a var of type IoDrvEthercatLib.ETC_CO_SdoWrite and include it in the code without adding an extra error. The problem only seems to affect the library. This is seems more an issue with my codesys set up rather than something with festo. I would like to know the possible causes. I understand most of the library manager features but it's not clear how to find the cause. Thanks

Post by wchin on Passing EtheNetIP adapter device into a Function Block to access it's IO ^{CODESYS Forge talk (Post)}
We are creating helper function blocks for our VFD(EtherNetIP). How should I set it up so that I can pass the device into and out of the Function Block so that ideally I can access the IO of the device by devicename.channelname. So something like for example we have a VFD with a start bit that is in the ControlWord channel and a SetVelocity that is a channel. And we want to create a Function Block called StartVFD. So I declare something like: FUNCTION_BLOCK StartVFD VAR_IN_OUT device: ioDrvEthernetIP.RemoteAdapter; END_VAR VAR_INPUT velocity : REAL; So in the code it would look something like device.SetVelocity := velocity; device.ControlWord.6 := True; We have a pretty basic eds file for our VFD and can update it if necessary. Thanks in advance.

Post by cdutz on Problems connecting to Codesys 4.9.0.0 runtime on my Wago PFC200 ^{CODESYS Forge talk (Post)}
Hi all. I am currently struggling to get my Wago PFC200 running the Codesys Runtime in version 4.9.0.0 working. I am using Codesys V3.5SP19. I updated the PFC200 to the firmware version 04.01.10(23) after having tried the latest version (04.03.03(25) from Wago and not being able to start the runtime. After reading version 23 was needed, I changed to that and at least was able to have it start the codesys runtime. I also installed the "Codesys Control for PFC200 SL 4.9.0.0" plugin for Codesys to install the Codesys runtime in version 4.9.0.0 as well as update the Gateway on the device. While I seem to be able to connect to the gateway on the PLC (the dot is green) and when doing a scan, I do now find my PFC200, which is a huge improvement to before, where with firmware version 25 it just failed to start the runtime and I never found any device when doing a scan. Unfortunately I don't seem to be able to connect to the PLC in codesys. I logged in via SSH and changed the password and I can see that this password is correct as the stuff in the Codesys PFC200 tools tab only works if I use my changed password. And I used those credentials to update the installed Runtime version, which the log claimed to have worked fine. Now whenever I try to connect to the device found in the scan, I get a authentication pop-up with empy device name, device address: 000A. As User I use "root" and as password the password that I changed it to. As a response I just get "Ungültige Benutzerauthentifizierung auf dem Gerät" (Eng. probably something like "Invalid user authentication on the device". What could I be doing wrong? Admittedly I'm a bit lost here :-/ Chris

You use very old codesys, maybe SP13? the newer sp17 libraries are in a format not compatible with your version. I suggest upgrading everything to at least SP17, but may as well go to SP20 Patch 2.
