Mode Switch

The Mode switch is located behind the module door. It can be used to place the PLC in Stop or Run mode. It can also be used to block accidental writing to CPU memory and force or override discrete data. The use of this feature is configurable. The default configuration enables Run/Stop mode selection and disables memory protection.
