The Schneider Automation 140-CPU-113-03 is a Modicon Quantum 80186 Concept Processor with 1 Modbus plus and 2 Modbus RS232. Its total memory is 512K. It has an internal RAM capability of 368 kB of processing power, with a clock frequency of 20 MHz. It can be used with a 2 NOM, NOE, CR or NMS communications module. For a distributed I/O system with 3 networks, the CPU requires the use of a 140NOM21x00 Option processor. Its 984 type memory is max 16k words. This product can work with Concept or ProWORX 32 software, and does not use a mathematical co-processor. It is recommended that its operating altitude remains under 5000 meters. This product is CUL and FM Class 1 Division 2 certified. Its ambient air temperature during operating conditions should remain between 0 to 60 °C.
The Schneider Electric 140CPU11303 has two 3-position front panel slide switches. The left switch can be used for memory protection when in the top position, and no member protection when in the bottom two positions. The right switch is used to select the communication parameters for the Modbus RS-232 ports. The top position assigns ASCII functionality to the port. The middle position assigns a remote terminal unit to the port. The bottom position gives you the ability to assign communication settings to the port in the software. All Quantum CPUs come with a 9-pin RS-232C connector that supports the Modicon Modbus comms protocol. Two rotary switches are located on the rear of the module. They are used for setting the Modbus Plus node and Modbus port addresses. The top switch (SW1) sets the upper digit in tens of the address; the bottom switch (SW2) sets the lower digit ones of the address. If 0 or an address higher than 64 is chosen, the Modbus + LED will stay “on” to indicate the selection of an invalid address.
