Cutting-edge Technology sigmaPAC®... centralized or distributed... the same solution!
Through the use of innovative hardware and software technologies, sigmaPAC allows for even the most demanding control solutions to be developed. Communication standardization and integration are guaranteed through the use of widely accepted industry standards- such as fieldbuses, the Ethernet network and serial communications with standard protocols -OPC technologies (OLE for Process Control) and the internet (Web Server).
IEC 61131-3 Standards guarantee the ease of development and maintenance of automation solutions.
The first low-cost PAC
sigmaPAC belongs to a new generation of programmable controllers, equipped with great processing capacity, known as PAC (Programmable Automation Control) and is characterized by:
sigmaPAC is here!
One of the characteristics of the sigmaPAC is its achitecture which enables the complete distribution of signal interface Units. The adoption of a standard fieldbus as its system bus allows third party devices to be connected and controlled by the sigmaPAC Central Unit.
Centralized or distributed... for us it's all the same!
Through the adoption of a high-efficiency standard protocol, the performance of sigmaPAC is not "penalized" if the required architecture is distributed. The I/O modules may be located directly next to the measurement or control points without the use of further interface devices.
Geographical and functional distribution
The onboard intelligence residing in each module allows basic processing to be distributed, and relieves the Control Unit from trivial and repetitive operations. Power-up and power-down functions allow the state of the output variables to be determined upon start-up or in the event of an interruption.
Synchronized... islands of automation
Parts of the system or machine automation may be managed independently by a Control Unit connected to a number of I/O modules.
It is possible to exchange synchronism data or messages with other units in different areas by using a secondary communication port available on the Control Unit. To this end, it is possible to choose whether to use the serial ports RS232/RS485 with Modbus protocol, or to use he other fieldbuses such as Profibus DP, DeviceNet, or CANopen.
"Single Click" Connection
The advantage in terms of reduced cable and cabling needs, as well as the indirect reduction in engineering activities required by the system or automated machine, is significant.
The Control Unit and the I/O modules are connected by standard CAT5 Ethernet cables.
sigmaPAC®- IEC61131-3 Ascon Auxiliary Library Ascon I/O Library
Standard IEC 61131-3 programming
The OpenPCS programming environment allows applications to be created in the 5 programming languages that comply with international standards.
Open PCS Automation Suite
The multitasking programming environment allows the project to be split into different tasks, executing sequentially or on the basis of a time cycle.
The variable declaration window guides users to structured programming. The 5 language editors aid in the correct execution of the application, automatically highlighting the keywords in the textual languages, and allow function menus to be accessed rapidly.
The diagnostics window allows any errors to be immediately identified during the project compilation phase.
Powerful and complete online debugging tools and useful off-line simulation allows the code to be verified from a functional point of view.
Vast function libraries to aid programming
Three libraries contain numerous function blocks for rapid and effective achievement of control and sequence routines.
Ascon Control Library
Includes Function Blocks aimed at configuring, exchanging data and activating advanced functions in the I/O modules.
sigmaPAC- Open connectivity to most major fielbuses
CANopen Port:
This port interfaces I/O modules and other CANopen devices like Operator Panels, Inverters, Motors, Valves...
Ethernet port primarily used for:
- Control Unit programming with OpenPCS
- HMI connection via the commonly used Modbus TCP protocol
- SCADA connection with the OPC server. OPC (OLE for Process Control) is a standard method available on most OPC client SCADA systems, and allows devices to be connected without writing any driver or communication code
Serial RS232 Port Used for:
- Setting up the Control Unit
- Ethernet port Configuration
- Setting up the CANopen port parameters
Every Control Unit can be equipped with optional fieldbus ports to interface other systems:
- Serial RS232+ RS485 with Modbus RTU Protocol. Operator Panels, SCADA, or external devices can be connected
- Profibus DP for PLCs or Operator Panels
- CANopen for communication with other Control Units
