Schneider Unity Pro standard CPUs Quantun 140system

Presentation

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 b 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

LCD display 

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.
