Post by rh-pk on v3.5 SP19 - Modbus TCP Devices - Channel Limit? ^{CODESYS Forge talk (Post)}
Hi, i found a solution for me. I had installed a 'old' version of CoDeSys (3.5.18 P5). I tried to add channels there, which works fine. I created a new project, added an Ethernet-Port, added a Modbus-Master and then I copied the ModBus-Slave from my working project to the new project. Now I could add more channels. I add the channels 10 and 11. Then I deleted (please make a backup before :-) the original ModBus-Slave in my working project and copied the extended Slave back to my working project. Surprisingly it is now possible to add new channels. Maybe this will help you.

Post by pernockham on Linking to IO during runtime with hot swap? ^{CODESYS Forge talk (Post)}
I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used. Codesys PLC (GVLs) |Profinet | |--PNIO-node-1--| | | AIO, | | DIO, | | CNT etc. | |--PNIO-node-2--| | | AIO, | | DIO, | | CNT etc. Ideally I think of a configuration through yaml/xml-files (the assignment/linking of the profinet nodes towards GVL-variables in the PLC as well as scaling, channel configration etc.). Would be grateful if someone could suggest library/-ies that can handle the following: - Verify what IO is connected to a device/node. - Hot-swap/assign link for IO towards GVLs, either automatically or through a HMI.

Post by askic on Generate FBs from source ^{CODESYS Forge talk (Post)}
Hello, I'm coming from Siemens (TIA) world and currently learning Codesys. I'd like to know if there is an option to add external txt file with ST code for creation of a function block and then use this file as a source file from which FB will be generated? For example, in TIA, there is an option add external source file to the project structure and then use option "Generate blocks from source". This would create a FB. Does Codesys have something similar? This external source file would look like this: FUNCTION_BLOCK Scaling VAR_INPUT x, k, n : REAL; END_VAR VAR_OUTPUT y : REAL; END_VAR VAR END_VAR y := k*x+n; END_FUNCTION_BLOCK

Change the actual time of your PLC. How to do this sometimes depends on the PLC you use. Please contact the vendor of the PLC to get this information. Or see the following example for using CODESYS date and time functions: https://forge.codesys.com/prj/codesys-example/date-and-time/home/Home/

Post by wiresplus on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
Hello, Depends on the architecture of your PLC. If the PLC is a PC-based item with a normal desktop environment, then you probably can. I find it simpler to install an IIoT Router in the panel, and use an encripted VPN to link to my office PC / Laptop on demand.

make sure the PLC and the programming PC have IP addresses that are on the same subnet, you'll have to know the default address of the PLC or you may need to connect to it with a special cable and use a software tool to set the IP address.

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

Post by micik on Python scripting - print whole project tree ^{CODESYS Forge talk (Post)}
Hello, I have found a script for printing device tree in Codesys project. This script is available as code snippet as an exmaple for using Python in Codesys. However I feel main documentation is lacking. For example, where can I find that object has "is_device" attribute? Code examples are given here: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_access_cds_func_in_python_scripts.html However, I have a question how to print the whole Project tree and not just devices? Of course I need to remove check: if treeobj.is_device: But simply removing this test condition will not produce what I want. I need to print PLC Logic, Application, ad other nodes in the Project tree. Where to find this documentation?
