8.2.4 Activating external pushbuttons
The I buttons and R buttons options enable the operator to operate an
easy800 standard in a harsh environment by means of external function keys
such as RMQ control circuit devices. easy800-SWD does not have this
function.
External pushbuttons that are connected to the local I input terminals or the
R input terminals of the expansion unit can thus take on the same functions
as the operator buttons of the device. The I or R input terminals are
permanently assigned to the function keys.
Table 22: Assigning Operator Buttons and I or R Input Terminals
The operator can produce the same effect as pressing the function keys
(e.g. DEL+ALT) by pressing two buttons (e.g. I7+I8) simultaneously.
External pushbuttons and operator buttons of the device are evaluated at the
same time thus enabling mixed operation.
In exceptional cases when the external pushbutton and the assigned
function key of the device are pressed simultaneously, the actuation of the
external pushbutton is ignored. This excludes the possibility of contradictory
operating states.
If an external pushbutton and an function key with different functions are
pressed simultaneously, this is interpreted by the device as a button
combination.
￫
You can only activate one of the two I or R button options.
Inputs that are activated as operating buttons are no longer
available for control tasks in the circuit diagram.
