Hardware description
The system described in this User Manual is mainly composed of three
components:
•Asconsigmadue series CPU (CU-02), ready to work with
OpenPCS EN 61131-3 compliant programming system;
•Asconsigmadue I/O-CB remote I/O series of modules;
• Infoteam OpenPCS programming system.
sigmadue CPU is a powerful processing unit, based on an ARM RISC
processor, different types of memory and several communication ports.
sigmadue
I/O-CB is a complete family of I/O analogue and digital remote
modules with special functions, based on the CANopen protocol over a CAN bus.
Infoteam OpenPCS is a powerful and useful standard programming system for
PLC applications.
It is a clearly structured, easily operated tool for editing, compiling, debugging,
managing and printing PLC applications in all the development phases.
OpenPCS supports EN61131-3 programming under Windows server 2003,
Windows XP SP2 or Windows Vista 32 bit.
Ascon sigmadue line is based on the sigmadue remote I/O system, combining
its functionality with the capabilities of a PLC. The modular concept and the
possibility of fieldbus networking means that you can adapt the system to your
requirements quickly and easily. This gives the sigmadue automation system
an especially economical price/performance ratio.
This User Manual handbook introduces you to work with sigmadue CPU line
and the Infoteam OpenPCS programming system.
It explains how to install the hardware and software, and how to start up the system.
Information on maintenance, troubleshooting and service are also included.

1-1 Architecture
From the programmer’s point of view, a complete system is made up as in “Figure
1.1 - Programming the sigmadue Control Unit” below:
Figure 1.1 - Programming the sigmadue Control Unit
In “Figure 1.1 - Programming the sigmadue Control Unit” the configuration station
(VT100 terminal) and the PC with OpenPCS are displayed as two different
devices, but it is possible to use just one PC to run both OpenPCS and a VT100
emulator (e.g. HyperTerminal).
1-1-1 Communication ports
The CPU has 3 fixed communication ports (see figure 2):
• The CAN port will be used for the connection, through a CANopen network,
to the distributed I/O;
• The Ethernet port (TCP/IP) will be used for the connection, through a LAN
network, to the PC with the Infoteam OpenPCS environment, for:
- Programming, Debuging and commissioning;
- Modbus TCP data exchange;
• The Service RS232 port will be used as:
- Configuration port of the device with VT100 terminal;
- Standard ASCII serial port;
- Modbus RTU data exchange.
In addition to the three mentioned fixed ports, a plug in board can be added (see
Ordering Codes), by which the communication capabilities are increased, e.g.:
• Two channels RS232/485 with Modbus RTU protocol (master or slave);
• Profibus DP (slave).
Pinout of all communication Ports are described hereafter and in the
“CU02 Installation Manual” [6].

Notes: 1. As the ON/OFF sequence of the LEDs has a specific meaning, it is important
that the user recognizes each LED status:
2. The first time some %M variable has been defined as RETAIN (see “Retain
Config Menu” on page 16), the system needs to reboot in order to create the
dedicated files. The error indication will disappear automatically.
Sequence Meaning
OFF the LED is not lit
Steady ON the LED is lit in a stable way
Blinking the LED blinks at a frequence of 2.5 Hz (slow)
Flickering the LED blinks at a frequence of 10 Hz (fast)
Single flash the LED lits once for at least 200 ms
Double flash the LED lits twice with pulses of 200 ms each
Triple flash the LED lits three with pulses of 200 ms each
