• insert and connect the HMI_LED function block in the
configuration
• make the connections for the indication LEDs in SMT (on the
binary outputs tab)
• The function blocks for LHMI are visible by default for PST and SMT.
• Use ACT or SMT to connect start and trip signals from application
functions to LED function blocks.
• PST
• The operation mode of the LEDs is defined in PST.
• GDE with assistance of ACT, for example
• to make the single line diagram of the primary process part.
• to make the dynamic links for the apparatus.
• to make the dynamic links for measurements.
ACT and local HMI function blocks
A set of special function blocks is available for all the operation element groups on
LHMI.
See the technical reference manual for more information about
function blocks.
List of LHMI function blocks that are available in ACT:
• LHMICTRL
• LEDGEN
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'.
PST and function block configuration
The operation mode of the LEDs must be defined per LED in PST, see
