Post by felipemsgarcia on Generic EtherCAT slave ^{CODESYS Forge talk (Post)}
Hello, Without much info, I would assume that this is an optional object on the EtherCAT network and it's either disconnected or the address doesn't match. I would look into the devices manual or contact the manufacturer for further assistance. And, I would have posted a new topic instead of using a non related one... Cheers!

Post by eschwellinger on connect IDE to plc that uses modem ppp ^{CODESYS Forge talk (Post)}
Which plc type is it? Easy connection is to install a Gateway on remote side - this is available for Windows and Linux devices Then just add a new Gateway in CODESYS (with the IP Adress of the remote device) -> then scan the plc via this new added Gateway

I added a main action to an SFC step, and then tried to delete it. There is no delete option in the SFC menu nor in the right click menu of the step. I deleted the action from the device tree, but building results in and error saying the action is not defined. Is there a way to delete a main action?

Previously, I have used ModbusEthernet_04 library for Wago for ModbusTCP Master communicational in Codesys V2.3. How to use same communication of similar UDT for Opto22 Groov PR2 PLC in Codesys V3.5 SP20. Can I use OSCAT library - Network -MB_Client or IODrvModbusTCP - ModbusRequest for this requirement?

Hello Zol6, Have you solved this issue? I use Festo PLC CPX-E-CEC-C1 to create alarm monitoring project. In CODESYS V3.5-SP18 I used the Alarm Storage object and have the same problem. Is it the PLC that is not compatible or the version of the library is not match? Best, wb16

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
It doesn't load differently codesys seems to be behaving differently. Original version of ethercat master in project archive is 3.5.15.50, compiler is 16.4 as is codesys I'm using. It builds fine in vm and not on local machine. The reason is not obvious. It builds on local machine with ethercat master at 3.5.16.0. I'd really appreciate advice

Post by vitorp on Visualization Toolbox in German ^{CODESYS Forge talk (Post)}
Hello, I am new to Codesys. I installed it on my computer and set the language to English. Most of the localized text appears in the correct language, but the Visualization Toolbox and the element properties are in German. I haven't found a way to change them to English. Can someone help me with this?

Post by matt-purcell on Which Lib to use, connect to a socket with URL instead of IP address ^{CODESYS Forge talk (Post)}
I've been searching through these libraries, syssocket and net base services and they all seem to use the same structure for IP address for the connect function, SOCKADDRESS. At a glance, it doesn't look like that'll work, maybe it's just missing in the documentation somewhere?? I'm wondering if anyone has done it.

Post by gatto on variables between two applications ^{CODESYS Forge talk (Post)}
Hello, I'm experimenting with two applications. I was able to start stop applications with the CmpApp library. Currently in my test the variables declared in the first application are not visible and writable in the second. I ask if there is the possibility of having variables that are visible both in the first application and in the second.

Post by kuegerls on SysProcessExecuteCommand2 and CANopen Device ^{CODESYS Forge talk (Post)}
I have now conducted some tests. The problem occurs when the Python script establishes an OPCUA connection, even if I only establish the connection without reading or writing any data. Is there another way to exchange data between Python and CODESYS without having to put in a lot of effort?

Hello everyone, following corrupted data on the SD card of our Pi3B+ provided with a machine, we reinstalled a CODESYS image for Raspberry Pi, but we cannot find the 4.9.0.0 runtime that is compatible with the project. Currently, the machine is on 4.1.0.0, and we tried a more recent version 4.13.0.0, but there are error messages. Thanks in advance.

Now that SP21 is out, what's the answer? I want to get a pointer to the TxPDO and RxPDO structs. I can generate a STRUCT declaration from the ESI file with a bit of Python. I just need to get the pointer from the ETC_Slave.

While trying to install CODESYS 3.5.17.30 (64-bit) on my Windows 11 computer, I'm getting the errors below. The first error occurs near the end of the installation. Once you bypass it, the installation returns the second error. Do you have any suggestions for a solution? By the way, I've tried this on several PCs, but I haven't found a solution.

Post by gseidel on SMC_ERROR SMC_CGR_INVALID_POSPERIOD ^{CODESYS Forge talk (Post)}
Hi blitz, that usually means that the modulo period, when converted to increments, is larger than 2^31. (The bus bandwidth is usually 2^32.) What is your "technical unit", do you program in angular degrees? And what is the modulo period? If you want you can post the drive configuration (screen shot of the "General" and "Scaling/Mapping" page). Best regards, Georg

Thanks Georg for responding. I have followed the suggestion mentioned in the real time problem. However, it does not solve the problem. The weird part is, the robot stops at the same position randomly and it does not stop when I increase the speed of the motion.
