Posted 10 Jun 2020 (edited) Hello, I have a project in which a bar code sensor and PLC need to communicate. The sensor is a Sick CLP510-2000 and uses RS-232, PLC is FX3GE-40M and does not have any extra moduls, such as the FX3G-232-BD. I was hoping the comunicatiom would be possible trough the minidin8 cable, until I got to GX Works2. It looks like I need the RS or RS2 function, but in help it says it only works with the extra moduls. Does anybody know, how I could make a function, like RS or RS2, or use one of them without the modul? Thanks in advance for any help you can offer :) Edited 11 Jun 2020 by Becky better fitting title Share this post Link to post Share on other sites
