Which PLC do you use? If it is a standard CODESYS Runtime (from the store), then maybe update the device in your project to the latest version. If it is not a standard CODESYS Runtime, then maybe contact the supplier.

Same Issue here. If I understood correctly codesys plans to discontinue the classic SymbolConfigurations. But somehow, the CommunicationManager doesnt seem to support structures or arrays.

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.

Post by r-c-r on SM3RaspiStepper 0.0.0.6 issue
CODESYS Forge
talk

Ok, so i made some tests in the meantime and i have some conclusions. It apears that the enable bit is activated only when a motion function is executed. I implemented a very simple program with MC_Power and MC_Jog. If i enable everything on MC_Power, the enable GPIO pin stays off. However, as soon as the MC_Jog function is used the enable GPIO pin turns ON and remains ON. In version 0.0.0.4 this is not happening. The GPIO enable pin turns on or off when the MC_Power is enabled or disabled. From this behaviour i understand that in version 0.0.0.6 the GPIO enable bit is activated together with pulse and dir pins when motion starts. When motion stops, enable bit remains with the last state (on in this case) and you cannot turn it off for example. For me this bit is useful because i can turn on and off the stepper drive with MC_Power function. Now i can turn it on, but never off.

Thanks, but unfortunately it does not work. I tried also the other function in the Properties window. What i tried also is to change the Visu-Style or looking for options.

Another way to resolve this is to set Codesys to use a specific version of the offending library under Placeholders in the Library Manager.

Mir ist nicht bekannt, dass CODESYS CAN FD in nächster Zeit für Prozessdaten anbieten will. Müsste ein CDS Supporter beantworten. Aber ab SP22 ist es zumindest für die Service-Verbindung verfügbar (Download/Debugging...). Soviel weiß ich.

It is not an error, but just an information message. You need to select the correct location in your device tree where you want to import the objects. E.g. select Application below your Device.

Leider etwas verspätet erst mal danke für die Antwort und für die Info. Ich habe jetzt ein Upate vom EtherCAT Master gemacht. Die Klemme funktioniert in ihrer Standardeinstellung. Bei den PWM-Klemmen geht das Umstellen auf DO, aber den Zähler kann ich immer noch nicht einstecken.

That's because the array only contains structures themselves, not references. It doesn't matter that what consists of each struectures unless they are not pointers.

Are these variables already declared in the IO list? It looks like it's trying to create new variables instead of mapping them to the existing ones.

Post by bmatlove on Variable Length Array - Cannot mix variable and fixed length dimensions?
CODESYS Forge
talk
(Post)
Using Codesys 3.5.18.30 I am trying to work with an array of variable length in one dimension, but known in the other dimension. For example, using an array that represents a list of items, each with an attribute profile. I do not know how many items will be in the list, but I know that every item has 5 attributes, like size, weight, etc. Codesys does not seem to be able to accept this. I have referenced Data Type: ARRAY OF documentation page, which is not explicit if variable & fixed length array dimensions can be mixed. In the VAR_IN_OUT scope, I initially tried MY_ARRAY : ARRAY [*, *] OF REAL; which was no problem, of course. I then modified it to MY_ARRAY : ARRAY [*, 1..5] OF REAL; which throws C0006: ', or ]' expected instead of '..' among consequent downstream errors. I then used the Auto Declare -> Array Wizard, which accepted (asterisk)-(asterisk) and 1-5 for 2-dimensional lower and upper bounds. It output: MY_ARRAY: ARRAY[*..*, 1..6] OF INT; which throws the same error stream. What's the deal here? Is this possible?

Post by shaunvdm on Canbus Slave SDO Read from Object
CODESYS Forge
talk
(Post)
Busy testing a solution to use Canbus Slave to replace a physical device and convert to Ethercat device but keep the Canbus Master in place. Master needs to Read SDO object 5FA2. In the Master PLC if i send the SDO with 8 bytes in message IE: 60B 40 A2 5F 00 00 00 00 00 i get my expected 58B 43 A2 5F 00 00 68 36 02 containing data back. Problem is if we issue a 4 byte command can send 60B 40 A2 5F. Surely the canbus slave should respond with a 58B 43 A2 5F 00 00 68 36 02 but it comes back as 80 A2 5F 00 00 00 00 08 - meaning this OBJECT does not exist. Is there a setting in the canbus slave driver for Canbus to allow the 4 byte command to read the SDO OBJECTS ?

Hi, okay here's the project, it's a modified version of "CNC Example 10: Programming Dynamic CNC Paths", no need for G Code text file (i have also tried with G code text file, same problem) in "PROGRAM PLC_PRG" you can set bStart to true, and the program should start running, go to "PROGRAM CNC" and you can see axis moving. lrXpos := IoConfig_Globals.XAixs.fSetPosition; lrYpos := IoConfig_Globals.YAxis.fSetPosition; Now you can can change the number of movements in the the "PROGRAM PLC_PRG" From this number of movements in "program PLC_PRG" BUF : ARRAY[0..32010] OF SMC_GEOINFO; xp : ARRAY[1..32000] OF REAL; yp : ARRAY[1..32000] OF REAL; to this number to this number of movements BUF : ARRAY[0..132010] OF SMC_GEOINFO; xp : ARRAY[1..132000] OF REAL; yp : ARRAY[1..132000] OF REAL; Now if you start the program again you should see an error in the "sMC_Interpolator: SM3_CNC.SMC_Interpolator;" function block Let me know if you can not get it running.

You can write any expression that evaluates to TRUE/FALSE in that property, you can also call a method from the property.

For reference this is fixed by installing the new codesys install with a separate repository folder. Completely resolved. If anyone else sees this. I would like to know why the persistent devices repository folder does not properly retain between installs though.

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.
