You can enable "Sync Producing" in the configuration of the CANopen Manager. Then this manager will send a SYNC message every interval you set. Depending on your PDO configuration, the CAN nodes can send a PDO on every Sync (cyclic-synchronous). If this is not possible, then as alternative you can send a low level CAN message with COB-ID 16#80.

The Modbus Master example must work. We have used this several times on multiple projects. See https://forge.codesys.com/prj/codesys-example/modbus/home/Home/

Hi, I tried some different libraries (CmpApp etc.) to find some global variables that I could read out as a variable in the codesys environment. Do any one of you know which libraries are best suited for this, and how I can read it out? My goal is to send messages, warnings etc. to the system that communicates to the PLC. Currently if something goes wrong I need to see the logfiles, or go online with the controller. I think I could save a lot of time if I could read the errors from our user interface that is connected to the PLC by TCP/IP.

Hello eschwellinger, what can I do if I need exactly this option to use the html5 controls, because I have the same problems with the displaced elements in WebVisu running in Internet Explorer. I have observed a different behavior in google chrome. Best regards, Etienne

Hi, I'm trying to implement a Ethernet/IP-Scanner in a blank project using Codesys 3.5.20.30. While compiling I got the following error messages (see attached screenshot) Any ideas or tips to solve this?

Hi, please check if "Support client animations and overlay of native elements" option is enabled. This option is very heavy to manage for the Webclients. I'm using the Pixsys srl "TC series" HMI with the code "P3" (so a 4+4 cores CPU) that runs very well also with this option active. The same CPU is mounted also in their WebPanel "WP" series, so you can try one of them if you want.
