Post by transmin01 on PCAN serial "No CAN driver found" ^{CODESYS Forge talk (Post)}
Hi, I am using a PCAN mini CAN board which has the Windows drivers installed on the target PLC. PCAN board can be seen in device manager. However, I am getting "No CAN driver found" error. I have read the post https://forge.codesys.com/forge/talk/CODESYS-V2/thread/44aae19318/ and have uncommented the CmpPCANBasicDrv driver in the CodesysControl.cfg file in development PC and have copied it to the target PC. Current CodesysControl.cfg file attached. Is there anything else I am missing? Regards

Your connection configuration should look something like the attachment. Consuming assembly O->T will be the hex of the assembly you want to reference for output data - I want 102 (DO Data Only) shown in the Wago web page 102 = 16#66. Producing assembly (T->O) is the assembly you require for input data - again shown in the Wago web page - I want 108 (DI Data Only) or 16#6C Then set the number of bytes as per the data in the Wago web page too (both 2 in my case)

Hi all, for a new project I'm looking for a redundant controller with EtherCAT fieldbus I/O. Actually I'm using Beckhoff and it works great! but there's not a solid redundancy yet... Does someone get experience for industrial application (not raspberry) for a redundant Codesys system? If yes please share some info (CPU / OS type, bus, number of managed I/O,... and especially feeling feedback (stability, bugs, performance)... Every suggestion is kindly appreciated!! Fabrizio

Post by jp23 on Unable to Connect to Modbus RTU Device ^{CODESYS Forge talk (Post)}
Hi all, I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1). Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."

Post by peterkcontrols on Copying 2 byte word to output ^{CODESYS Forge talk (Post)}
Hello. I am using codesys 3.5. I would like to know if it is possible to set a variable to an output without declaring in. I have defined a STRUCT and within this struct I have a Struct for inputs called I and a struct for outputs called O. I have declared a variable of the type of this Struct, I would like to set or alias the value in this variable to an input/output value of an IO block that has a module on the ethernet tree. Is it possible to copy the contents of %IW0 -> STRUCT.I ? The size of both of these is 2 bytes. I understand that I can declare a variable with the input like Input01 AT %IX0.0 : BOOL; However how can I make STRUCT.I.D00 AT %IX0.0? Is this possible? Thanks

Post by qkkk on Device Scan ^{CODESYS Forge talk (Post)}
Hello all, I have developed a custom I/O driver in CODESYS that communicates via a Unix Domain Socket. In my DeviceDescription.xml, I have set up the following: <scan supported="true"> <scanfbinstance fbname="IOScanDevice"> The goal is to allow the user to scan for connected I/O modules from the CODESYS GUI ("Scan for Devices") and automatically populate the device tree with detected submodules.</scanfbinstance></scan> The function block IOScanDevice is implemented in the driver library and added to the main device's FB instances. However, when I initiate the scan from the GUI, nothing appears to happen the function is not executed. Is there an example project or driver (open source or from CODESYS Forge) that demonstrates a working custom scan implementation?

I want to cancel the automatic address allocation for all IO mappings. If I directly set the automatic_iec_address in class ScriptIoMapping to False, the address becomes None. So I reset manual_iec_address with itselfs value. It only work with the Input IOMapping . For output, it reports an error: "Invalid address: The channel type 'Output' requires address type '%Q'." I checked the description file ,both accessRight are total same. Does anyone know what causes this?

I am using a WAGO PFC200 PLC as an etherCAT master and a Keyence IV3-G120 with DL-EC1A attached as an etherCAT slave. I am using CODESYS V3.5 SP21 Patch 3. I was able to set up mailbox communication and can see values changing accordingly, but I want to know how I can map these values and reference them in my program. I am able to map the process data objects in the 'EtherCAT I/O Mapping' tab, but there is no where to map the mailbox values in the 'CoE Online' tab. Is there a way I can reference one of these values in my code?
