Modicon Quantum Presentation
Modicon Quantum CPUs are a family of high-performance programmable controllers based on 486 and Pentium processors, and are compatible with Unity Pro software.
Some of the features implemented in these CPUs include:
●Superior scan times and I/O throughput.
●Ability to handle interrupts, timed and I/O based.
●Handling of Fast task, as well as a Master task.
●Memory expansion through PCMCIA cards.
●Multiple communication interfaces embedded in the CPU.
●A user-friendly diagnostic and operation LCD display on the front panel of high-end models.
The processors offered can be differentiated by their memory capacities, processing
speeds and communication options.
Memory backup, protection and expansion
The CPUs store the application program in a battery-backed internal RAM. The battery is located on the front of the module and can be serviced while the CPU is running.
To protect the application program from inadvertent changes during operation, the processors feature a key switch on the front panel. This key switch can also be used to start and stop the CPU. The 140 CPU 311 10 processor only has a memory-protect slide switch.
A memory protection bit, to be set in confi guration mode, is also available to lock any program modifi cation (via the programming PC or downloads).
High-end processors 140 CPU 651 50/60 and 140 CPU 671 60 have 2 slots for a PCMCIA card:
●An upper slot (no. 0) to receive memory extension cards (programs, symbols, constants and/or data fi les).
●A lower slot (no. 1) to receive memory extension cards specifi c to the data fi les.
Built-in communication ports
Quantum CPUs support:
●Two Modbus RS 232 ports (Modbus RS 485 with 140 CPU 651 p0 and 140 CPU 671 60 processors)
●One Modbus Plus port
Depending on the model, Quantum processors can include:
●A 10BASE-T/100BASE-TX Ethernet TCP/IP port (RJ45 connection)
●A USB port for connecting a programming terminal
Some CPU models have an LCD display (2 lines of 16 characters) with brightness and contrast controls. Through a keypad and the display the CPUs can be diagnosed, some confi guration parameters can be set and the CPUs can be started and stopped.
Hot Standby (redundancy)
The Quantum 140 CPU 671 60 processor is dedicated to managing Hot Standby functionality. It has an Ethernet 100 Mbps fi ber optic link and the Hot Standby function can be diagnosed through the LCD display.
The 140 CPU 311 10 and 140 CPU 434 12U processor front panels comprise:
1 A display unit consisting of 7 LEDs:
●Ready LED (green): the CPU has passed the power-up diagnostic tests
●Run LED (green): the CPU has been started and is solving logic
●Modbus LED (green): communications are active on the Modbus port
●Modbus Plus LED (green): communications are active on the Modbus Plus port
●Mem Prt LED (orange): write-protected memory (activated memory protection switch)
●Bat Low LED (red): the battery needs replacing or is not present
●Error A LED (red): indicates communications error on the Modbus Plus port
2 One backup battery slot
3 One slide switch for selecting the Modbus port communication parameters
●One slide switch (140 CPU 311 10 model) to write-protect the memory.
4 One key-operated switch (140 CPU 434 12U model):
●Stop position: the programmable controller is stopped and program modifi cations are not authorized
●Mem Prt position: the programmable controller is either stopped or is running and program modifi cations are not authorized
●Start position: the programmable controller is either stopped or is running and program modifi cations are authorized
