Schneider 140CRA93100 RIO drop adaptor module Modicon Quantum

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.
