Post by spilin on All devices lost for all installed version ^{CODESYS Forge talk (Post)}
hello. After installing the latest version of codesys (3.5.20) from codesys installer, I had a problem. All my devices disappeared. Both PLCs and IO modules and network devices disappeared from my list. I browsed through the Windows files and I can find them in the programdata/codesys/devices folder. The files remain there, but they are not available within codesys (same error in all installed versions) which in this case are 3.5.16 and 3.5.19. Does anyone know how I can reimport or resynchronize my devices folder again? Thanks

Post by athuum on Error 'Library not found' and 'Unkown type' ^{CODESYS Forge talk (Post)}
Hello, I am getting the following error and warning when trying to download a project into a PLC: - Library CmpTargetVisu has not been added to the Library manager, or no valid license could be found - Unkown type: 'CmpEventMgr.EventParam' As far as I can see, both are included, and licensed, in the library manager (see image). What could the problem be, and how would I resolve this?

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
I succeed to change the device to PI_SL but still the same problem of the I2C device switching between running and not running. the only difference with your project is that yo use I2C_master device version 4.7.0 and i 4.7.13, for GPIO i also use the 4.7.13 version and you the 4.7.0. Can you send me the older version of the Raspberry PI pheripals library, because i cannot choose lower version then 4.7.10 for the GPIO and I2C_master device

Post by johnbomb on Ignore Dependencies When Loading Package? ^{CODESYS Forge talk (Post)}
I'm trying to load a .package into Codesys 3.5.21, but the package is intended to only work with Codesys 3.5.18.0 and is configured with dependencies on the specific versions of other packages included with 3.5.18.0, and 21 has newer versions so the package will not install. I would like to install the package anyway to try and get things working on a newer Codesys version, since for some reason the installer for .18 errors out and doesn't fully work in my environment, but .21 seems to work fine.

I use codesys version 3.5.20 and crevis Ethercat cards. AC drive is master axis and Servo drive is slave axis Thanks in advance

Post by svn123 on In Simulation Mode, logic is not executing ^{CODESYS Forge talk (Post)}
Please check the attached snapshot. I am converting an int to real and storing in rVlv01_SV and then scaling the value using LIN_TRAFO. In the bottom Status Bar of Codesys, both RUN and SIMULATION are visible. When I enter value 100 as input to INT_TO_REAL instruction and press Ctrl-F7, the value can be seen at the input but the logic seems not to work. I searched for help but could not find anything relevant. What could be the reason. Codesys ver3.5.11 svn

Post by toby on SM Drive license error ^{CODESYS Forge talk (Post)}
Hi albert1999 and forest, I hope you are well. I too am wondering if you have found any solutions? Im working with a RPi and a Omron R88D-ETH servo amplifier. The SoftMotion is timing out after 30min without the license, but I cant figure out how to license it, and I seem to have some compatibility issues between my RPi license and any SoftMotion licenses. Did you guys have any luck? Thank you very much for any assistance offered. Toby

Post by warrumungi on Beckhoff EL6652-0010 with Codesys ^{CODESYS Forge talk (Post)}
Hi Has anyone successfully used a Beckhoff EL6652-0010 Ethernet/IP slave terminal through an EK1101 EtherCAT coupler, or similar, and been able to set it up through Codesys? It seems there is no driver for it, and it can't be done? The only option would be to use the Ethernet/IP capability of the controller directly with one of its ethernet ports and a Codesys Ethernet/IP adapter + module and routing it through EtherCAT by tunnelling it through via an EL6614 switchport? Any advice would be appreciated. Billy.

Post by ojz0r on INT_TO_WORD function not working ^{CODESYS Forge talk (Post)}
That calculation will not work the way you expect it to. If PumpFillSpeed is limitied to 0-50 then the only whole number would be 50/50 = 1 everything else is 0.0-0.9999... and since you are using word and integer only 50 would work since there is no representation for mantissa in integer values. Declare a temporary real variable and do the calculation and then do a REAL_TO_WORD in the DRV2Speed assignment.

Post by wbj0t on System libs and I/O Drivers ^{CODESYS Forge talk (Post)}
Hi everyone. My question about: where I can learn (read or watch) an info about codesys workflow through the system IO libs? I want to know how to implement I/O drivers by my self. In the system libs I see many interfaces, methods etc... But there is no explanation about them, just names of methods and fields of the FBs. I know about this page: https://forge.codesys.com/drv/io-drivers/doc/Generic/ There is so BIG the device description file and not so clear explaining of the attributes and elements, also some elements or attributes missed at it all. Yes, there are code examples on this page, but, so shortly and, for example, code about Modbus drivers is absent. And even if I try to add the IoDrvFB with lib, I get and error, something like: "failed to load IoDrvFB driver". And what about the book of codesys that written by Gary Pratt? Is there information about system libs and drivers in this book more clearly? Thank you :)

Post by ferrim on IEC 61499 ^{CODESYS Forge talk (Post)}
IEC 61499 is probably something more complex than what you have correctly said so the prospects are interesting but we cannot ignore that it came out almost 20 years ago and has not won many hearts. I started to explore this world with a PLCnext controller because I love these devices based on RT Linux and Codesys is somehow usable with them but I have made little progress and I feel like inside a nutshell in the middle of the sea ;-) Gary's voluminous and precious book is always on my desk...
