Modicon Quantum PLCs This articles of Modicon Quantum PLCs and includes new products, such as CPUs, power supplies and communication modules, which extend the field of application of the range in the various standard and safety industrial application areas.
With an already wide selection of I/O modules, and an already extensive offer in terms of communication on fieldbuses and networks, Modicon Quantum is even better suited to the needs of continuous or semi-continuous industrial processes and control of large infrastructure sites.
Capitalizing as it does on more than 25 years’ experience in redundant processing architectures, and fully meeting safety requirements for people, production installations and their environment, Modicon Quantum is the ideal solution for applications requiring maximum availability in complete safety.
The Modicon Quantum offer is, de facto, inherently designed for high availability applications in the areas below: * Petrochemicals * Metallurgy * Cement * Energy * Tunnels * Airports * Water treatment * Mines * Hydropower
The CPUs for the Modicon Quantum automation platform are based on highperformance processors and are compatible with Unity Pro software. Numerous functions are included as standard in Quantum CPUs: * Superior scan times and fast I/O acquisition * Ability to handle interrupts (timed and I/O based) * Handling of Fast task, as well as a Master task * Memory expansion using PCMCIA cards * Multiple communication ports integrated in the CPU * Ease of diagnostics and maintenance via the LCD display block on the front panel of high-end CPUs The CPUs offered have different memory capacities, processing speeds and communication options.
Protected backed up memory
As standard, the CPUs store the application program in a battery-backed internal RAM. This battery is located on the front of the CPU and can be replaced while the CPU is running. A switch enables the application to be made secure against malicious tampering via a remote connection. To protect the application program from inadvertent changes during operation, the CPUs feature a key switch on the front panel to protect the memory. This key switch can also be used to start and stop the CPU. The 140CPU31110 CPU only has a memory-protect slide switch. The high-end 140CPU65150, 140CPU65160, 140CPU65260, 140CPU67060, 140CPU67160, 140CPU67260 and 140CPU67261 CPUs have 2 slots for a PCMCIA card: * An upper slot (no. 0) for a memory expansion card (programs, symbols, constants and/or data storage) * A lower slot (no. 1) for a data storage memory expansion card Besides the large-capacity internal RAM, the high-end 140CPU65860 and 140CPU67861 CPUs have 1 slot for a PCMCIA card: * One slot for a data storage memory expansion card
Built-in communication ports
Quantum CPUs incorporate, depending on the model: * Two RS 232 Modbus ports (1 RS 232/485 Modbus port for 140CPU6pppp CPUs) * One Modbus Plus port * One TCP/IP 10BASE-T/100BASE-TX Ethernet TCP/IP port (100BASE-FX for 140CPU67p6p Hot Standby CPUs) * One USB port for connecting a programming PC terminal for the CPUs
Depending on the model, the CPUs have an LCD display (2 lines of 16 characters) with adjustable brightness and contrast controls. The keypad associated with the display can be used for diagnostics, access to certain configuration parameters and starting and stopping the CPU.
