Welcome to the Modicon PLC Blog! We are just getting up and running but check back soon for all sorts of posts about troubleshooting, upgrading, and documentation of Modicon Quantum, Compact, and TSX PLC’s. We are a distributor of those Schneider Electric Modicon modules and many others – feel free to contact us at firstname.lastname@example.org if you need a quote! Also, keep in mind that we are not affiliated with Schneider Electric; we are only a distributor so please visit their site at www.schneider-electric.com if you bought directly from them and need help with those products. Thanks for stopping by!
