Function keys

Functionality
Local Human-Machine-Interface (LHMI) has five function buttons, directly to the left of
the LCD, that can be configured either as menu shortcut or control buttons. Each button
has an indication LED that can be configured in the application configuration.
When used as a menu shortcut, a function button provides a fast way to navigate between
default nodes in the menu tree. When used as a control, the button can control a binary
signal.
Operation principle
Each output on the FNKEYMD1 - FNKEYMD5 function blocks can be controlled from
the LHMI function keys. By pressing a function button on the LHMI, the output status of
the actual function block will change. These binary outputs can in turn be used to control
other function blocks, for example, switch control blocks, binary I/O outputs etc.
