Hi CodeShepherd, I tried to export the library in Twincat in 2 ways: - via export function of the "Library Repositry" - look up the relevant file in "Explorer" --> see screenshot "Lib-file Twincat.png".   I assume you tested at your side with that same file. Am I correct? When importing I keep getting the same message "Missing string table..." Attached 2 pieces library in "Twincat-libs.zip": - "Tc2_ModbusRTU.compiled-library" taken from export function - "Tc2_ModbusRTU.compiled-library-ge33" copied from folder 3.4.2.0 of TwinCat Kind regards, ...

As a colleague of AndroidZz, I am currently testing the set-up with a CtrlX and RS485 card from Beckhoff (EL6021). The EL6021 is connected to the CtrlX over EtherCat. Wiring is OK, test with Beckhoff-PLC works well. Basis for testing on CtrlX is "ModbusRTUtest.zip" as posted by TheCodeCaptain a few posts above. - CXA_ModbusRTU.CXA_S20.IH_S20ComConfiguration works flawlessly. "bInOperation_ComConfig" immediately becomes TRUE. - when calling "IH_S20MBRTUMaster" I get an error ACCESS_ERROR with ErrorIdent of CXA_TABLE-16#0C0F0000-16#0C850031. Some questions: - where can I find information regarding 16#0C850031 - how do I determine the slot number of the RS485 card? In the example uiSlot is := 3... my RS485 card is as 3rd module after the EtherCat slave station...? Kind regards, ... View more
