LED mapping
Function

The HMI devices Operator Panel (OP), Multi Panel (MP) and Panel PC have LEDs in their function keys. These LEDs can be activated by the controller. In a particular situation, this allows the controller to activate an LED, for example, to tell the operator which key to press.

Requirement

To be able to activate an LED, an LED tag or an array tag must be set up on the controller and specified as an LED tag during configuration.

LED assignment

The assignment of individual LEDs to the bits in the LED tags is specified when you configure the function keys. You specify the "LED tag" and the assigned "bit" in the properties window in the "General" group.

The bit number "bit" identifies the first of two consecutive bits that control the following LED states:

Bit n+ 1 Bit n LED function

0 0 Off

0 1 Flashing

1 0 Flashing

1 1 On permanently
