1. Introduction
1.1 Welcome to EPSON RC+ 7.0
Welcome to the EPSON RC+ 7.0 Project Management and Development Environment.
EPSON RC+ 7.0 is used to develop application software for the Robot Controller.
EPSON RC+ 7.0 features
Operable on Windows
Integrated application development environment
Communicates with the Controller by USB or Ethernet
Allows you to connect one computer with multiple Controllers
Multi simultaneous session
SPEL+ programming language
A powerful, easy to use BASIC-like programming language that supports multi-
tasking, robot motion control, I/O control, and networking.
I/O systems including Digital I/O boards and Fieldbus I/O
TCP/IP and RS-232 communications
Background task
Controls entire system
Database access
Vision Guide option
Integrated vision robot guidance
RC+ API option
Enables you to control the system using standard Microsoft .NET programming
environments including Microsoft Visual Basic and Microsoft Visual C++.
Security option
Allows you to administrate all EPSON RC+ users on your system. It also includes
usage auditing, so you can track how many hours are spent using the system, and if
changes were made.
Conveyor Tracking option
Enables one or more robots to pick parts from moving conveyors using vision or
sensors.
PG Motion System option
Allows you to use third party motors and drivers to control auxiliary equipment such
as XY tables, slides, etc.
ECP option
Supports CP motion relative to a fixed point.
GUI Builder option
Integrated GUI development tool
Force Guide option
Allows a robot to use torque/force sensing and measurement
Force Control
Force is controlled or measured by force sensor.
1. Introduction
2 EPSON RC+ 7.0 (Ver.7.5) User's Guide Rev.7
Absolute Accuracy Calibration
Makes sure the coordinates and trajectory match the actual robot position and
trajectory.
This function is used for some options and applicable models.
VRT option
Enables you to reduce vibration of Robot Motion.
PartFeeding (Option)
You can easily supply parts by the Robot.
Safety Function (Only for the Controller with Safety Board, some of them are option.)
Sets limit of operation speed and operating area for the robot, it allows you to make an
application controlling robot safely.
1.2 System Overview
EPSON RC+ 7.0 software, which is installed to the computer connected to the robot
controller, contains several components that enable you to control an entire robotic work
cell. EPSON RC+ 7.0 communicates with the controller using USB or Ethernet.
EPSON RC+ 7.0 and the Controller can be used in following environments:
Slave system
The Controller is PLC or PC cell slave.
Application is developed with EPSON RC+ 7.0.
After saving the object code to the Controller, it does not
need to be connected to the computer.
The Controller is controlled by I/O or fieldbus.
Standalone system
Controls the robot and peripheral equipment as the robot
controller.
EPSON RC+ 7.0 displays the simple operator window in
AUTO mode.
By using RC+ API option, .NET application can be
controlled.
Offline development
system
Program edition and project build can be checked on the
offline PC.
Simulation system
EPSON RC+ 7.0 on the PC which is connected to the
Controller can execute the program without the actual I/O or
robot by using the virtual I/O and dry run.
1.2.1 Controller
RC700 series
The RC700 series Controller is a powerful robotic work cell controller that controls our
SCARA robots and 6-axis robots.
Controller features
Sophisticated yet achieving reliability and stability
Built in Motion System
The motion drive system can control up to 6 axes simultaneously and 1 robot,
and can add up to three drive units (RC700, RC700-A only)
Includes standard I/O
Wide variety of options
For detailed information on the Controller, refer to the RC700 controller manual.
