5 Trigger block
5.1 Function
♦ The Trigger block is an optional signal path component. It contains all
necessary parameters to process trigger signals (impulses). The input
signal (impulse) is compared to a trigger level to create an event
sequence (series of reference time points).
♦ The trigger operating type (auto-trigger resp. fixed-value trigger), trigger
level and hysteresis are defined by the parameters of the Trigger block .
♦ The Trigger block is necessary for the execution of impulse-based
measuring and monitoring tasks, e.g.
• Speed measurement
• Rotor-synchronous measurement tasks (e.g. vector
measurements)
• Cyclic measurements tasks (e.g. Cycle-DC measurement)
♦ In the operation type Automatic Trigger the automatically evaluated
trigger level can be read through the User Terminal or through the COM
interface of a downstream OPC-server.
♦ The level for the automatic trigger can be given at the output of the DC-
OUT Module as a voltage signal.
5.2 Parameters and setting ranges
5.2.1 Parameter list
♦ <Trigger type>
This parameter defines whether the trigger level will be automatically or
manually determined.
With the automatic trigger the trigger level is calculated new for each
trigger cycle from the signal increase. The actual trigger level
corresponds to 50 % of the signal increase from the previous trigger
cycle. With the fixed-value trigger the trigger level is maintained
constantly at the defined value.
Trigger type Automatic Fixed-value
Works pre-setting Automatic
♦ <Signal slope>
This parameter determines whether the trigger event will be initiated by
an increasingly positive or an increasingly negative signal slope.
Signal slope Positive Negative
Works pre-setting Negative
