You could use the FBs ETC_CO_SdoWrite and ETC_CO_SdoRead

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 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

Post by timvh on FB string and naming ^{CODESYS Forge talk (Post)}
Really not clear what you are trying to do, but isn't a Struct enough? So add an object of the type DUT to the Application. Then create a structure TYPE ST_Sensor : STRUCT sName : STRING; uiNumber : UINT; END_STRUCT END_TYPE Then in you application add an instance of this Structure stSensor1 : ST_Sensor := (sName := 'my sensor', uiNumber := 1); or use it like this stSensor1.sName := 'my sensor';

Hi all. I'm pretty new to codesys. Maybe a few months. I've had on and off issues here and there. This issue I cant figure out. The top line is one of 2 that I had. The other one has mysteriously left. the 2nd and 3rd showed up after I restarted the program. I'm not sure how to take care of them. Please help!

Post by timvh on CAN Open Manager - varible of SYNC ^{CODESYS Forge talk (Post)}
You can enable "Sync Producing" in the configuration of the CANopen Manager. Then this manager will send a SYNC message every interval you set. Depending on your PDO configuration, the CAN nodes can send a PDO on every Sync (cyclic-synchronous). If this is not possible, then as alternative you can send a low level CAN message with COB-ID 16#80.

Hi, the option "Support client animations and overlay of native elements" needs a very powerful graphics accelerator in the system. I'm using the Pixsys srl "TC series" HMI with the code "P3" (so a 4+4 cores CPU) that runs very well also with this option active.

Is it possible under CODESYS V3.5 SP18, to connect a split (german Leitungsverzweigung) with an existing block (e.g. AND-module)? Or to connect the output of an existing block to the input of an existing block (e.g. OR-block)? Any ideas? P.S.: Sorry for the german title, I do not know how modify the title.

WAGO will use 0-32767 as the raw units. Note a value of 3 means over/under range. Map that IO however you please, then scale in your program using any of the available libraries or with your own simple y=mx+b scaling formula to get to the engineering units you desire. Inverse for the AO to get back to 0-32767.

Post by timvh on Colors look different when logged in and running ^{CODESYS Forge talk (Post)}
At the top of the Visualisation Properties View, you can enable the "Advanced" options. This will give you access to more properties than what you currently see. There might be a variable linked to the "advanced" colour property where the fill colour is determined by the value of this variable (dword).
