So as Sebastian suggested , I will use I/O Coupler from Beckhoff why make my life harder 😊
Thanks for the ifo. regards, ajith PS: The forum serves its purpose, helps to make informed decisions to new comers, cheers folks!! keep up the good work, I shall definetely report my Progress. ______________________________________________________________________________________________ Ajith Boralugoda President CNC Lanka (PVT) Ltd 143/1 Meemanagoda Road Kalalgoda Pannipitiya Sri Lanka Tel/Fax : 0094112762624,009411493770 Hotline : 0094755002390 e-mail : a...@cnclanka.com www.cnclanka.com CINCINNATI-SRILANKA (www.cincinnati-srilanka.com) Sole Agents for: MultiCam CNC Solutions from US ( www.multicam.com) AlphaCam (www.alphacam.com) and ArtCam (www.delcam.com) from UK.
