Hello, I am facing a problem with the new Softmotion 4.17.0.0 version. Has anyone encountered a similar problem, what is the solution? I would be happy if you could share it. Problem description: -- "SMC_FreeEncoder" encoder axis is the master, -- The motor of the servo driver on the EtherCAT bus is the slave axis. -- When the MC_CamIn block executed, the InSync output is activated. However, although the master encoder axis position value changes, there is no movement in the slave servo axis! Test steps: 1-) EtherCAT servo axis installed, configured and motion test was performed with MC_Jog. No problem. 2-) Softmotion general axis pool > SMC_FreeEncoder was added and pulse amount configuration was performed. No problem. 3-) Incremental encoder actual count value was transferred to the "SMC_FreeEncoder.diEncoderPosition" variable as DINT under the ethercat task in every cycle and the encoder axis position value was observed. No problem. 4-) A simple CAM table with a 1:1 ratio was created under the project tree. (For example: Simply, when the encoder rotates 1 turn, the motor will rotate 1 turn.) 5-) The SMC_FreeEncoder axis enabled with MC_Power and brought to the StandStill state. 6-) The MC_CamTableSelect block was run with default input values ββ(all absolute) and only the Cam table name was specified. The Done output was seen successfully. No problem. 7-) The MC_CamIn block was activated with default input values ββ(absolute) and only the master encoder axis name, slave servo axis name, CamTableID input pins was specified and then "Execute" input set to TRUE. 8-) The InSync output information of the MC_CamIn block observed as TRUE. However, although the encoder axis value changed, the position value of the slave axis did not change at all, it did not move. It always remained at 0.0mm. 9-) When I repeated the same steps above, only changing the master axis to SM_Drive_Virtual instead of FreeEncoder and gave movement to the virtual axis, this time the slave axis moved successfully. However, when the same steps and operations are performed with the same IDE just downgrade SoftMotion version from 4.17.0.0 to 4.10.0.0, everything works normally and without problems as expected in MC_CamIn block with FreeEncoder master. (By the way, The used IDE version is Codesys V3.5 SP20patch3.) Best Regards Imdat

... you say 1.6 Nm is only enough torque to unscrew a loose bottle cap ... This the the value of torque: from 1,2 Nm to 1,4 Nm that is cosidered acceptable for an old people. 1,6 Nm the torque considered acceptable for general use caps.

Hi, If the string length in the GetRecipeNames method is lower than the default value, there will be a problem with the resulting Recipe file names. For example; When the method in the link is called, let's say the defined string length is 19. In this case, the string content is corrupted as in the image. strArr: ARRAY[0..9] OF STRING(19); https://content.helpme-codesys.com/de/libs/Recipe%20Management/Current/pou-RecipeManCommands/GetRecipeNames.html The same problem does not occur when the string definition is made in the default size. strArr: ARRAY[0..9] OF STRING; FYI Regards, Imdat

I have been trying to set an array value to a JSON structure of this form: {"key": [1,2,3,4]} While I have been able to create the key and set its value to an empty array, I've not had any luck in putting any value in that array. objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindex); iValue2: ARRAY[0..3] OF INT:= [1,2,3,4]; The two lines of code above produce {"key6": []} . The second line essentially has no effect.

Hello! I use CheckBounds (POUs for Implicit Checks). But I have a problem. I use an array as an VAR_IN_OUT of Function Block. If I try to monitor the array of variable length ([* ]), its does't work. The CheckBounds POU isn't called. If I use the array of fixed lenght ([lower..upper]), the CheckBounds POU is called. Why?

What variable of the axis indicates it is a modulo of finite axis? I want to check that in the code, to adopt my motion code between the two types.

Post by manuknecht on Persistence Manager does not save alphabetically first value
CODESYS Forge
talk
(Post)
I have several libraries which contain values that should be saved on a PLC. As apparently no Persistent Variable List is available within Libraries, I use the Persistence Manager to create a Persistence Channel in the Project which imports the library. I then specify the persistence channel in the library using the {attribute 'ac_persist':='PersistenceChannel_CT'} specifier. This generally works very well and gives me exactly the properties I require. However, it came to my attention that the (alphabetially) first value from the library is not saved in the created ASCII file. When checking the content of the Persistence Channel, it shows all the variables as defined in the library. But the created file does not contain the first value and it is not restored after restart or reset. (see attached picture) I disabled Periodic Saving and set xSaveOnChange to TRUE and so the file usually updates immediately after changing one of the values. When changing the first value, it does not update which is consistent with this value not being saved. I also created a sample project and library from scratch which shows the same issue both using a Raspberry Pi and using a Linux machine. Does someone know what the reason for this could be or did someone make similar experiences? Looking forward to hearing your suggestions. Thanks in advance and best wishes Manuel

When you use a string value 0 will be the end terminator. Everything after this will not be in the string. I guess byte 2394 has a value 0.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
