Post by jp23 on Unable to Connect to Modbus RTU Device ^{CODESYS Forge talk (Post)}
Hi all, I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1). Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."

Post by siscu on Raspberry i2c master device ^{CODESYS Forge talk (Post)}
I want to implement an extended I2C master for Raspberry Pi Control. I was hoping for it to be as easy as creating a library with a FB that extends i2cMaster and associating it with a device following the forge drivers documentation, but I haven't managed to make it work as the driver behaves only as an i2c slave. I'm thinking this is because the forge forum only talks about extending i2c, and the master portion is omitted since most users won't want to add a custom one. I'd like to know if I'm doing something wrong. Is it really possible to make an I2C master extension device? If so, are there public examples we can check out? Any info on this topic will be appreciated.

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 durallymax on Persistent Vars ^{CODESYS Forge talk (Post)}
Looking for a better way to manage Persistent Variables. We tend to have local vars in our FBs that need persistence through downloads as the systems are updated/altered on a regular basis. Retain would suffice if we had an easy mechanism to backup and restore like we can with Persistent variables and recipes. Although not having to remember that step with Persistent variables is preferred. We're running into issues with persistent storage capacity (WAGO PFC200) using the Persistent variable list (and adding all instances). It appears there are many ways to handle this, some with recipes, some with files, others with application manager. Is there a solution that exists that is as simple as declaring as Persistent and managing elsewhere? Or do we need to move onto periodically writing CSVs?
