Schneider Modicon PLC,Modicon Quantum PLC Series

With its modular and flexible architecture (extension racks, remote I/O (including Ethernet remote I/O),
processors, PCMCIA memory…), the Modicon Quantum PLC meets the needs of the most complex applications, in both centralized and distributed topologies. It offers an Ethernet Modbus™ TCP/IP port and a web server directly integrated into the processor. It supports distributed I/O and the use of standard/ open communication protocols. Ethernet communication modules embrace the newest ODVA standard for EtherNet/IP, which combined the former EtherNet/IP standard with the Modbus TCP/IP standard. This provides even more flexibility in distributing I/O and managing
Ethernet communications.

Redundant Quantum CPUs have a dedicated built-in Ethernet port (100BASE-FX) that provides rapid synchronization of all data from the primaryCPU to the secondary or standby CPU, making the Modicon Quantum PLC hot standby system the solution for time-critical applications that can’t afford unscheduled down time.When combined with Unity™ Pro programming software, the hot standby offer effectively meets the needs of users: more memory, enhanced performance, and built-in hardware redundancy. What’s more, it also offers supremely easy system setup, and improved management
and communication functions – all without impacting performance

The Unity Pro development software is the only programming tool you need to fully develop, test, debug, and manage your applications that leverage the current Modicon line of industrial controllers.Its versatility, ease-of-use, and built-in library of pre-tested application function blocks allow users with multiprocessor applications to share ideas and information visually, so individuals and teams can benefit from their collective experience and work together more effectively. As a result, you save time and money by reducing on-site development, installation times, and debugging across your
application’s entire life cycle.

Unity Pro offers five IEC 61131-3 languages as standard. Each section of code can be programmed in the language of your choice, adapted to each processing operation. The edit, debugging, and operation tools are accessible whatever the
language used.
• LD: ladder diagram
• IL: instructions list
• ST: structured text
• SFC: sequential function chart
• FBD: function block diagram
In addition to the five standard IEC languages, there is an additional LL984 language that allows you to import applications from legacy Modicon PLCs such as the Modicon 984 PLC that used 984 Ladder Logic
for programming.
