CHAPTER 12: REGISTERS
12.1 RX-371 Resources
12.1.1 Overview
This section defines the resource limits that a programmer needs to know when writing a program using
the RX-371. The RX-371 combines operator interface (display and keypad), local and remote I/O (analog
and digital), networking, and controller, into a single product. In addition, the RX-371 has graphical
capabilities. The controller portion of the RX-371 products is programmed in ladder logic via the
Windows-based Cscape (Control Station Central Application Programming Environment) package.
