Post by ph0010421 on Axis EtherCAT address ^{CODESYS Forge talk (Post)}
Hello SDO will write to the drive, not the axis, so you need to pass in the ethercat slave: VAR_IN_OUT Axis: IoDrvEthercatLib.ETCSlave; END_VAR Then you can get the address with: Axis.PhysSlaveAddr (as UINT)

Go to the menu Tools - CODESYS Installer. Here you can manage your add-on packages. Go to Browse, find CODESYS Communication and install this add-on.

Hello, I encountered this same error. I was able to resolve it by allocating more messages when I open the network driver (ctMessages:= 100). By default it is set to 25.

Post by mandeepahujaifm on Exception when OPCUA datasource disconnects from Server ^{CODESYS Forge talk (Post)}
@eschwellinger - We are experiencing the exact same issue. RunTime 3.5.19.70 and IDE V3.5 SP21. It's 100% reproducible. All you have to do is disconnect the network cable for about 10 minutes. OPC UA Crashes and requires a reboot to fix.

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.

Post by timvh on Import from XML problem ^{CODESYS Forge talk (Post)}
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.

Post by abuckie on i2c master not running ^{CODESYS Forge talk (Post)}
Hello, I am trying to create an Ethernet/IP device that can read analog signals, do some basic logic on it and then hand communicate the results to an Ethernet/IP master. I am using the Raspberry Pi to experiment with this as I would ultimately like to drive a display as well. I have loaded up the runtime on the Pi and got the digital I/O working. I have an ADS1115 ADC to I2C board and I can't get it to work, I get a message telling me the i2c master is not running and I am not sure where to start with this. Is there a manual for running CODESYS on the Pi or something like that I am missing? I found this post and opening the project in CODESYS V3.5 SP21 it seems like tons of this wouldn't convert properly https://forge.codesys.com/forge/talk/Runtime/thread/f1400b71b6/ I have added in the library and device manually and copied the structured text program but lost at what to do if the core functionality of the master is not running. I appreciate any help, thanks.

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.

You can use function blocks like TCPServer to start the Retro Bowl College server and TCPAccept to handle incoming connections, with CAA.Handle simply acting as a reference ID for each resource.

In my case, I used a different version of gateway. ex)3.5.18.5 sysTray gateway start did not work, so I terminated it and made it work with 3.5.18.3 in "codesys installer" "Settings" and was able to connect to the PLC.

Post by tk096 on SMC_ReadNCFile2 is always busy ^{CODESYS Forge talk (Post)}
Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

It sounds like you are trying to use the device user management, but you can use the visu user management found in the Visu Manager for this.
