Post by winki on Modbus TCP & RTU with Control for Linux SL ^{CODESYS Forge talk (Post)}
For small project, I would like to use my industrial computer as a PLC + Industrial Computer. Like that I can save the cost of one PLC. That why I am using Codesys on Linux. With the nic it is not working. I already set the IP adress with /etc/network/interfaces. Can it comes from there ? looking to "Control Linux SL" docuemntation it should work with rtu.

we use successful for many years the KEB MFI terminal for Profinet, EtherCAT, Ethernet/IP,... You'll need a EtherCAT Coupler as "head" from KEB, Kendrion or Berghof. It's all the same board inside: https://www.kebamerica.com/products/ethercat-bus-coupler/ Or the coupler with 16Di/Do integrated: https://www.kebamerica.com/products/ethercat-digital-io-module/ last year I got a EK1100 with EL6731 Profibus treminal runnig. But it was a lot of reverse engineering and thinkering in Codesys and TwinCAT to be done, to get it up, fulfilling my needs. Good luck!

How can this be resolved? Regards, Imdat

An update note. Still using linux/Qemu. Still happy, but sometimes some things are harder. I lost the "bridge" connection to my VM (meaning for instance I couldnt "scan network" and find local units. Have spent tons of hours to find out why. Finally it seems the traffic got blocked by the firewall/iptables so needed to set rules for that. So friendly note that rules must allow forward traffic to/from you configured host bridge device.

I'm getting this error on one of my projects. Searching for it I came across this https://www.codesys.com/fileadmin/data/Images/System/Releaseinformation/Patch-Note-CODESYS-Visualization-4300.html which says it was a bug VIS-1394, fixed in Visualization 4.3.0.0. I'm using a previous visu version, what is the cause of this error, and what can be done to work around it?

Post by richard-wang on Codesys recipe manager - what does it do? ^{CODESYS Forge talk (Post)}
Hi All Thanks for sharing this information. For whom may not know why always get error code 16#4000 or 16#4002 while performing Recipe commands, the root cause is There is a line need to be inserted in CODESYSControl.cfg file, which is PlaceholderFilePath.1=/var/opt/codesys/PlcLogic/ I am using Pi, therefore the above path is set to my pi unit, after adding above line to my cfg file, all the Recipe commands work fine. But I still do not know how and when this file got modified though.

Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hello jacobwago, I believe that the limit is fixed in the editor, but not in the driver package. There seems to be no link between the driver setting and the editor. Otherwise, I don't know why the input (>10) is blocked, but the function is available. Unfortunately, I cannot offer you any other solution apart from the one mentioned above. Kind regards

Post by davidbo on Modbus: Is there a way to get the channel index from the channel name? ^{CODESYS Forge talk (Post)}
When I use the FUNCTION_BLOCK ModbusChannel I have to sepcify the integer iChannelIndex It can easily go wrong if one has many channels. It would be better if one could use the name. Is that possible? Attached a snippet of the channel name and the channel index to the left.
