How do you memory protect the M340 CPU

The M340 can be placed into memory protect by designating a discrete input in the M340 configuration. The input that you designate must exist and must be hardwired
to allow a toggle between 0>1 or 1>0 for memory protect to be turned off and on. Use only topological references for the memory protect input. It prohibits the transfer of a project into the PLC and modifications in online mode, regardless of the communication channel. The Run and Stop commands are authorized.
