Hi, one more point. I have been able to create Property of Text which is added to Global text list so it´s fine. But as soon as I use Frame configuration I lose all other properties but some very basics. I need to have still possibility to set Input configuration because my element is Button. Do you know how to make visible all standard properties + my own properties created in Frame configuration? Thanks a lot. M.

Dear Support, I have i950 wants to connect with Beckhoff EtherCAT coupler BK1120. There are 2 GSD files for BK1120. 1. BK1120 without MDP.(EtherCAT ESI Device Description (XML)) 2. BK1120 with MDP. (EtherCAT BKxxx (MDP) configuration files) When connecting the BK1120 with i950, scanned devices detects BK1120 without MDP from ESI No1 above. But the KL1408 & KL2408 not detect because they have ELxxxx IO type. When manually insert BK1120 with MDP, the KL1xx8 is able to add manually also but the error shows and Install Missing Descriptions appears. The questions; 1. Why the error occurs? 2. Can the i950 connect with KLxxxx IO type or not? Regards, Shafiq

Hi, Yes this should be possible, you should find the CodesysControl.cfg file on your plc. Open this with a text editor, and change the placeholder filepath for alarms. You can find the Placeholder filepath in the CodesysControl file under Sysfile.

Build: CODESYS 3.5 SP19 Patch 1 (64-bit) Host OS: Windows 10 Target: Linux SL I have a project with programs in Structured Text and Ladder Diagram. When I try to use the Find function, it works for the Active Editor; however, when I try to use Find for the Entire Project, I get the error "Object reference not set to the instance of an object." I know what this error means in the context of the program, but I have no idea why the find function is returning this error. The variable I am searching does not matter: it happens with all variables. Any help with this will be greatly appreciated. I generally use the Find function quite often as I am developing and not having it is really slowing me down.

You can simply excute the function block SMC3_ReinitDrive to the referred axis.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
