Product details

Processor for the MELSEC Q rack

The Q01CPU is the rack-mounted CPU in the MELSEC Q series. Its 94 kB memory and 56 kB program capacity set the application envelope for medium-scale automation tasks. Programming is via RS232C using GX Works2 or an operating panel.

Memory and program sizing

With 94 kB total memory and 56 kB dedicated to program capacity, the Q01CPU fits control sequences of several thousand steps—enough for a machine cell or a small line. Exceeding that means stepping up to the Q02 or Q06 series.

I/O handling architecture

The CPU processes analogue and digital signals, but field wiring connects through separate I/O modules on the backplane. No built-in I/O on the CPU itself—plan for a rack with input and output modules matching your signal types.

Frequently asked questions

What memory does the Q01CPU have?

It has 94 kB total memory and 56 kB program capacity.

What input types does the Q01CPU support?

It supports both analogue and digital input types, but requires external I/O modules for field wiring.

Will the Q01CPU drop into a panel designed for the FX5-8EX/ES?

No. The Q01CPU is a rack-based CPU for the MELSEC Q series, while the FX5-8EX/ES is a digital input module for the iQ-F series. They have different form factors, bus architectures, and power supplies.
