Widely used
Users from many different industries have long placed their trust in Mitsubishi modular PLCs to control their processes or machines. In fact, ARC’s 2004 Worldwide PLC Survey ranks Mitsubishi as the world’s largest volume producer of PLC products.
All round control
Working tirelessly and reliably, existing CPUs from Mitsubishi such as the AnS, AnSH, QnAS and QnASH have brought innovation and ease of use to many shop floor applications – qualities shared by the latest generation of control technology: System Q.
Compatibility
For customers who are considering changing to System Q there are many benefits: increased processing speed, multi CPU capabilities, and wider ranges of modules all designed to make the system engineer’s life just that little bit easier.
Things to remember
When upgrading from AnS or QnS systems to System Q, the part numbering is simple and familiar – Q replaces A1S, for example; A1SX80 becomes QX80. Programs can be transferred from an existing installation using Mitsubishi’s GX and GX IEC programming software.
