1. The remainder of this section shows the menus available for this module and briefly discusses the commands available to you Keystrokes The keyboard commands on these menus are usually not case sensitive You can enter most commands in lowercase or uppercase letters The menus use a few special characters that must be entered exactly as shown Some of these characters will require you to use the SHIFT CTRL or ALT keys to enter them correctly For example on US English keyboards enter the command as SHIFT and Also take care to distinguish the different uses for uppercase letter eye I lowercase letter el L and the number one 1 Likewise uppercase letter oh O and the number zero 0 are not interchangeable Although these characters look alike on the screen they perform different actions on the module and may not be used interchangeably Page 82 of 147 ProSoft Technology Inc September 24 2010 MVI56 MNETR ControlLogix Platform Diagnostics and Troubleshooting Modbus TCP IP Interface Module with Reduced Data Block User Manual 4 2 3 Main Menu When you first connect to the module from your computer your terminal screen will be blank To activate the main menu press the key on your computer s keyboard If the module is connected properly the following menu will appear MVIS6 MNETR COMMUNICATION MODULE MENU Display Menu Block Transfer Statistics C Modu
