Below is a diagraph of the 140CPU42402's external features.

Two, three-position slide switches are located on the front of the 140CPU42402. The left switch is utilized for memory protection when in the top position and no memory protection in the bottm and middle positions. The three-position slide switch on the right is used to select the communications parameter settings for the Modbus RS-232 ports. The module defaults to bridge mode when the front panel switch is set to RTU or ASCII mode. When networking controllers, a panel device connected to the CPU's Modbus port can communicate with the controller to which it is connected, as well as log any nodes in the Modbus Plus network
