Application Configuration tool and local HMI function blocks
A set of special function blocks is available for all the operation element groups on LHMI.
See the technical manual for more information about function blocks.
List of LHMI function blocks that are available in Application Configuration tool:
•
LHMICTRL
•
FNKEYMD1 to FNKEYMD5
•
LEDGEN
•
GRP1_LED1 to GRP1_LED15
•
GRP2_LED1 to GRP2_LED15
•
GRP3_LED1 to GRP3_LED15
The function blocks for the LEDs are organized in function blocks per LED. They can be placed
close to the logic where the information per LED is built in Application Configuration tool.
Figure
describes the basic LHMI and the operation element groups. These are the 15 LEDs and
their belonging text elements on the LCD [A]. They are operated by the keys [a] and [b].
The other group is the five function keys with their IEDs and the corresponding text elements
on the LCD [B].

Function block LEDGEN
•
Handles an external acknowledge signal as source to acknowledge the LEDs.
•
Generates an additional pulse for general purposes whenever the LEDs are acknowledged
by the operator.
•
Generates a pulse whenever a new LED signal occurs. It may be used to trigger an
acoustical alarm.
•
Handles the timer
tReset and tMax for the LED operation mode 'LatchedReset-S'.
