1.3 MiniOCS / MiniRCS Resources
1.3.1 Overview
This section defines the resource limits that a programmer needs to know when writing a program using
the MiniOCS / MiniRCS.
A MiniOCS / MiniRCS combine local I/O (analog and digital), networking, and controller, into a single
product. The MiniOCS also provides an operator interface (display and keypad). The controller portion of
the MiniOCS / MiniRCS is programmed in ladder logic via the Windows-based Cscape (Control Station
Central Application Programming Environment) package. Each MiniOCS / MiniRCS provide a set of
resources for use by the ladder logic control program as indicated in Table 1.2. The table shows the
resources available in MiniOCS / MiniRCS products. Note that although each register type inherently
consists of either 1-bit or 16-bit registers, all registers can be accessed via User Screens and/or Ladder
Code as 1, 8, 16 or 32-bit values or as ASCII character strings.

The faceplate is made of Marnot XL Polyester by Tekra. The material is
resistant to most corrosive substances found in industrial environments. The
material also holds up well in most industrial conditions. If used outdoors, the
materials can yellow or crack.
