Post by imdatatas on Unrecoverable SoftMotion state after switch to PreOp ^{CODESYS Forge talk (Post)}
Dear @alimans, Additionally, As far as I know since starting from Softmotion V4.18.0.0 automatic restart behaviour for an axis has been changed for this issue. See below explanation from release notes. "With CODESYS SoftMotion 4.18.0.0, the behavior of SoftMotion axes after a loss of communication to the servo drive has changed. Now, an automatic reinitialization is performed as soon as the communication is established again. Before, an explicit call to SMC3_ReinitDrive had to be performed. An example for a loss of communication is that the cable to one of the drives is unplugged." Regards, imdatatas

Post by timvh on Version management ^{CODESYS Forge talk (Post)}
This depends on what you want to achieve with installing the latest version and how you manage your projects and repositories. Maybe you also want to update your device (right click on it to update) or maybe your device is depending on certain versions of libraries (go to the library manager in your project and download the missing libraries). An option is also to first create a projectarchive of the current project you have before you install a new version of CODESYS. Then you can open this projectarchive in the new CODESYS version. Especially if you install the latest version of CODESYS in a Sandbox.

Post by fless on No source code available for profinet library ^{CODESYS Forge talk (Post)}
looks like you are running in a bug in the newest version 4.4.0 of the profinet library or the new library triggers a bug in your code. did you update your profinet device too? you could try to downgrade to an older version of the library. via library manager - placeholders, double click Profinet 4.4.0 in the library column and choose an older version.

Post by tk096 on Motion FB Error ^{CODESYS Forge talk (Post)}
Hi, Softmotion Robotics does not support tracking in/out to dynamic coordinate systems with relative movements. Is MC_MoveLinearAbsolute an option? See SMC_RELATIVE_MOVEMENT_TRACKING_CS in https://content.helpme-codesys.com/en/libs/SM3_Error/Current/SM3_Error/SMC_ERROR.html Concerning the other error: Do you use any motion function blocks of SM3_Basic to move a single axis of the robot in your application?

Post by rickj on Defining local variables that can be independent with several users. ^{CODESYS Forge talk (Post)}
You need to create an array with one element for each possible user. I usually define these arrays in the root screen. FrameIndex : Array [0..MaxUsers] OF INT; Then use the global CurrentClientId (defined by one of the VISU libraries) to index the array element used to select the frame. FrameIndex[CurrentClientId]

The codesys application license allows the use of up to 4 fieldbus instances (eg Modbus). I need to use more instances than that. Can I use the Modbus library instead? Does this usage require a license? Similar to other libraries such as CanOpen, Modbus TCP...

Post by tk096 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Hi, I suppose that you are referring to the error code "SMC_FB_WASNT_CALLED_DURING_MOTION"? Starting of Softmotion version 4.15.0.0 the instance path of the function block that has not been called is logged into the device log. This might help you to identify why it has not been called.

Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The new (UTF8) string library is faster and can handle large strings. https://content.helpme-codesys.com/en/CODESYS%20String%20Libraries/_strlib_start_page.html PS, in CODESYS, the maximum string length is not 255 characters. The String functions of the standard library are limited to strings of 255 characters. But you can use other (memory) functions to handle strings larger than 255 characters.

Post by dantheman on Connecting to SoftPLC Only Works By Turning Off Modbus Ethernet Port ^{CODESYS Forge talk (Post)}
I've also noticed that when I turn off "enp1s0", suddenly the source IP for the ModbusTCP changes to that of "enp2s0", which is what makes sense to me. When I turn it back on, the source IP remains that of "enp2s0".

Post by tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html
