The Quantum 140CPU43412A CPU is a single-slot programmablecontroller with built-in executive memory, application memory andcommunication ports. All memory components are on board so noadditional chips or cartridges are necessary.Quantum CPUs use flash memory technology to support the CPU’sexecutive memory and instruction set. Flash is a state-of-the-art,nonvolatile memory technology that enables downloadable fieldupgrades as new features become available.The application program can be stored in either battery-backed RAMand/or Flash RAM. The battery is located on the front of the CPU andcan be serviced while the CPU is running. To protect the applicationprogram from inadvertent changes during operation, the140CPU43412A features a memory-protect switch. An LED goes onwhen this switch is activated.The 140CPU43412A CPU has two Modbus® ports and one ModbusPlus™ port. Simple rotary switches on the back of the CPU are used toset the network address of the Modbus Plus port. Each device on aModbus Plus network must have a unique address in the range 1 … 64.
