I understand. Thanks. But if I have a big DT with many rows and columns? It takes much time to edit it in UDT - cell by cell. With Excell you can grab, drag, drop cells, use formulas etc. Is there any way to edit DT in Excell first? I know how to do it when I have access to the ladder. How to do it when I have only SD card suite, PC , PLC with SD and cable without access to LD?
