The Quantum 140CPU43412A CPU is a single-slot programmable
controller with built-in executive memory, application memory and
communication ports. All memory components are on board so no
additional chips or cartridges are necessary.
Quantum CPUs use flash memory technology to support the CPU’s
executive memory and instruction set. Flash is a state-of-the-art,
nonvolatile memory technology that enables downloadable field
upgrades as new features become available.
The application program can be stored in either battery-backed RAM
and/or Flash RAM. The battery is located on the front of the CPU and
can be serviced while the CPU is running. To protect the application
program from inadvertent changes during operation, the
140CPU43412A features a memory-protect switch. An LED goes on
when this switch is activated.
The 140CPU43412A CPU has two Modbus® ports and one Modbus
Plus™ port. Simple rotary switches on the back of the CPU are used to
set the network address of the Modbus Plus port. Each device on a
Modbus Plus network must have a unique address in the range 1 … 64. 5,8
