Additional Information

The Modicon 140-CPU-434-12A uses Concept, ProWORX 32, and Unity software with a 80486 processor and a With mathematical coprocessor. It has a clock frequency of 66 Mhz and an internal RAM capability of 896 kB. It can use a 6 NOM, NOE, CR, or N

The Schneider Electric 140CPU43412A is a Quantum CPU module located on the Quantum local I/O backplane. The CPU uses a digitally operating electronic system using programmable memory for storing the user’s instructions. These settings are then used for functions like logic, process sequencing, timing, coupling, and arithmetic. This allows the user to control machines and processes through digital and analog outputs. The Quantum CPU also serves as the bus master for controlling the local, remote, and distributed I/O of the Modicon Quantum system. The 140-CPU-434-12A uses a single slide switch to select the comm parameter settings for the Modbus (RS-323) ports. The Quantum CPU hardware defaults to a bridge mode when the front panel switch is set to RTU mode or ASCII mode. When networking controllers together, a panel device connected to the CPU Modbus port can also communicate with the controlly that it is connected to, as well as log into any nodes that are on the Modbus Plus network. If the switch position is set to stop, the application in Flash memory is not being transferred to the internal RAM, and a warm restart of the application is then triggered. From Start or Mem Prt, it will stop the controller if it is running and voids any programmer changes. When the switch position is set to Mem Prt, the same behavior occurs. However, from Stop or Start, it prevents program changes and the controller run status remains unchanged. If the switch is in the Start position, the application in Flash memory is automatically transferred to internal RAM when the CPU is powered up. A cold restart is triggered as well. From Stop, it enables programmer changes and starts the Schneider Automation 140CPU43412A. From Mem Prt, it accepts the programmer’s changes and starts the controller if it is stopped.
