1.2 MiniOCS and MiniRCS Product Description

1.2.1 Functions and Features

The MiniOCS provides controller, I/O, operator interface, and optional networking capabilities in one unit.
The MiniRCS has the same functionality as the MiniOCS except that it does not have local operator
interface capabilities. Both the MiniRCS and the MiniOCS support a remote operator interface through a
PC connected to the Mini unit’s built-in network or serial port. The remote operator interface (Remote
Text Terminal) is particularly useful when using the MiniRCS, which does not have a physical front panel
screen or keypad.

The MiniOCS is mounted in a panel door; the MiniRCS is designed for backplate mounting. Both the
MiniOCS and the MiniRCS can be used in CsCAN or DeviceNet networks. To use the MiniRCS in a
DeviceNet network, a DeviceNet file can be downloaded from Cscape’s Firmware Update Wizard.

PAGE 10 15 MAR 2003 CH.1
MAN305-04

A variety of MiniOCS / MiniRCS models are available. Each model comes equipped with one factory
installed I/O board. Models of the MiniOCS / MiniRCS, which vary according to the type of I/O board
installed, are available in non-network and network versions. Network versions contain an additional
connector allowing connectivity to networks.

MiniOCS / MiniRCS devices have Serial and CAN (Controller Area Network) communication abilities.
The units contain a standard 9-pin RS -232 port for programming/debugging, monitoring and network
administration from an IBM -compatible PC. MiniOCS / MiniRCS models, which have built-in networking
capabilities, use CsCAN (pronouned “Sea-scan”) protocol and standard CAN network hardware. CAN­based network hardware is used in the controllers because of CAN’s automatic error detection, ease of
configuration, low-cost of design and implementation and ability to operate in harsh environments. The
MiniOCS / MiniRCS can also be used in DeviceNet networks. Networking abilities are built-in to the
MiniOCS / MiniRCS and require no external or additional modules. When several MiniOCS / MiniRCS
units are networked together to ac hieve a specific purpose, the system acts like a large parallel­processing controller.

The MiniOCS / MiniRCS have standard features consisting of the following:

• 24 VDC powered • Integrated Bezel

• One Internal I/O Module • Real-Time Clock

• RS-232 Programming Port • Flash Memory for easy field upgrades

1.2.2 Cscape Software

Cscape Software (pronounced “Sea -scape”) is used with the MiniOCS / MiniRCS, OCS, and RCS
products. (The part number for Cscape is HE500OSW232.) Cscape stands for Control Station Central
Application Programming Environment. The Windows -based software package is easy to use and aids in
the integration of a CAN-based Distributed Control System. The program is used for configuring
controllers and I/O Modules. Cscape is also used for programming MiniOCS / MiniRCS ladder logic,
programming user displays for the MiniOCS, configuring the network for global digital and analog data,
setting system-wide security and monitoring controllers in the system. Provided there is one serial
connection to one node on the network (i.e., CsCAN Network), the operator has control over the entire
system. The operator can upload, download, monitor and debug to any node on the network.

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.

User Registers

User Registers (%T, %M and %R) are used to store application-specific Mini data. This data can be
accessed via User Screens and/or by Ladder Code.

a. %T Register
A %T Register is a non -retentive 1-bit memory location, used to store application-specific state

information.
b. %M Registers
A %M Register is a retentive 1-bit memory location, used to store application-specific state information.
c. %R Registers
A %R Register is a retentive 16 -bit memory location, used to store application-specific values.

HMI Registers

HMI Registers (%K and %D) give the user access to the OCS or RCS keypad and display.
The MiniOCS has a membrane keypad and text-based LCD display, allowing the operator to enter and

display general and application -specific information. This same information can be entered and displayed
for the MiniRCS (and MiniOCS if desired) via a remote PC using Cscape’s Remote Display Terminal
function.

a. %K Registers
A %K Register is a non -retentive 1-bit memory location (contact), used to store the state of a function key

on the Control Station’s keypad. If the function keys are set for momentary mode, a function key’s
associated %K register will be ON as long as the function key is pressed. If the function keys are set for
toggle mode, a function key’s associated %K register will toggle each time the function key is pressed.

b. %D Registers
A %D Register is a non-retentive 1-bit memory location (coil), which can be turned ON by Ladder Code to

cause the corresponding User or Alarm Screen to be displayed.
c. User Screens
A User Screen is a combination of fixed text or graphics, along with variable Data Fields (called Graphics

Objects in the MINIOCS), which together fill the LCD display screen. These screens are defined via
Cscape di alogs and are then downloaded and stored into the Control Station’s Flash memory. User
Screens can be selected for display by operator entries on the keypad, or by Ladder Code.

d. Data Fields
A Data Field is an area on a User Screen where variable data is displayed and edited. The source data

for a Data Field can be any of the Control Station’s Register resources as defined above. The field size
and display format is programmable via Cscape dialogs.

PAGE 16 15 MAR 2003 CH.1
MAN305-04

e. Text Tables
A Text Table is a list of Text Items, which can be used in a Data Field, to display descriptive words and

phrases to describe the value of a Register, instead of displaying numeric values. A simple example of
this, would allow the strings “OFF” and “ON” to be displayed, instead of 0 and 1, to describe the state of
the %I4 digital input. The maximum number of Text Tables and Text Items per Text Table is shown in
Table 1, but the number can be further limited by overall User Screen memory usage.

Physical I/O Registers
Physical I/O Registers (%I, %Q, %AI and %AQ) give the user access to the Physical I/O Module

data. This data can be accessed via User Screens and/or by Ladder Code.
a. %I Registers
A %I Register is a 1-bit memory location, which is normally used to store the state of one of the digital

inputs associated with a Physical I/O module. When used in this way, %I registers are non -retentive. All
extra %I registers, which are not associated with physical inputs, are retentive, and can be used just like
%M registers.

b. %Q Registers
A %Q Register is a non-retentive 1-bit memory location, which is normally used to store the state of one

of the digital outputs associated with a Physical I/O module.
c. %AI Registers
A %AI Register is a 16 -bit memory location, which is normally used to store the value of one of analog

inputs associated with a Physical I/O module. When used in this way, %AI registers are non -retentive.
All extra %AI registers, which are not associated with physical inputs, are retentive, and can be used just
like %R registers.

d. %AQ Registers
A %AQ Register is a non-retentive 16-bit memory location, which is normally used to store the value of

one of the analog outputs associated with a Physical I/O module.

Global Data I/O Registers

Global Data I/O Registers (%IG, %QG, %AIG and %AQG) give the user access to the Network Port’s
Global I/O data. This data can be accessed via User Screens and/or by Ladder Code.

a. %IG Registers
A %IG Register is a retentive 1-bit memory location, which is normally used to store a global digital state

obtained from another Control Station on the network.
b. %QG Registers
A %QG Register is a retentive 1-bit memory location, which is normally used to store a digital state to be

sent as global data to the other Control Stations on the network.

c. %AIG Registers
A %AIG Register is a retentive 16-bit memory location, which is normally used to store a global analog

value obtained from another Control Station on the network.
d. %AQG Registers
A %AQG Register is a retentive 16 -bit memory location, which is normally used to store an analog value

to be sent as global data to the other Control Stations on the network.
e. Network Port
The CsCAN Network is based on the Bosch Control Area Network (CAN), and implements the CsCAN

Protocol which is designed to take maximum advantage of the global data broadcasting capability of
CAN. Using this network protocol, up to 64 Control Stations can be linked without repeaters, and up to
253 Control Stations can be linked by using 3 repeaters. For more information regarding CsCAN
Protocol, refer to the CsCAN Protocol Specification document.

DeviceNet is an “open” higher layer protocol, which is supported by products from multiple vendors. In an
OCS or RCS, DeviceNet can be loaded as a replacement for the CsCAN Protocol Message Layer, and as
a result, the OCS or RCS becomes a DeviceNet Slave device. Note that the Mini still implements the
CsCAN Protocol Command Layer with respect to the RS -232 programming port. For more information
regarding DeviceNet Protocol, contact the DeviceNet governing body (ODVA).

Ladder Code

The Ladder Code, stores ladder instructions generated by Cscape. This Ladder Code is downloaded and
stored into the Control Station’s Flash memory, to be executed each controller scan, when the controller
is in RUN mode.

1.4 MiniOCS / MiniRCS Models

Because there are several models of MiniOCS / MiniRCS models available, the MiniOCS / MiniRCS can
be used in a wide range of applications. The MiniOCS consists of an Operator Control Station, and the
MiniRCS consists of a Remote Control Station. Each model comes equipped with one factory installed
I/O board. The models vary according to the type of I/O board installed and are available in non-network
and network versions. Network versions contain an additional connector allowin g connectivity to CAN
networks. Refer to Additional References on page 18 to locate model-specific information for each Mini.

CHAPTER 2: INSTALLATION

2.1 MiniOCS Mounting Requirements

2.1.1 MiniOCS Mounting Procedures (Installed in a Panel Door)

The MiniOCS is designed for permanent panel mounting. To install the MiniOCS, follow the instructions
below.

1. Prior to mounting the MiniOCS, observe requirements for the panel layout design and adequate

clearances. A checklist is provided on page 25.

2. Cut the host panel as described in the Figure 2.1 - Figure 2.6.

Warning: Make sure the power and network connectors are removed from the MiniOCS.

3. Insert the MiniOCS through the panel cutout (from the front). The gasket material needs to lie

between the host panel and the MiniOCS panel.

4. Install and tighten the mounting clips (provided with the MiniOCS) until the gasket material forms a

tight seal. (See Figure 2.7.)

Caution: Do not over-tighten. Over-tightening can potentially damage the case.

5. Connect the communications, programming, and power cables to the MiniOCS ports using the

provided connectors.

6. Begin configuration procedures for the MiniOCS models.
