Upon successful comparison of trigger signal and trigger condition, bit 0 is

set in parameter P-0-0037, Oscilloscope: internal trigger signal (trigger

status) but the trigger is not released. It is thereby possible for the master

to signal the trigger event via the real-time status and control bits to

several drives at the same time and to release the trigger.

As real-time control information, the parameter P-0-0036, Oscilloscope:

external trigger signal can be parameterized both in the real-time

channel of the interface and as hardware input. This allows triggering at

internal signals that are preset via

• the master communication

- or -

• an analog or digital input

Parameterizing the Oscilloscope Function

Recording Duration

The recording duration is determined according to the following

relationship:

0032)-0-(Pmemory of size 0031)-0-(P resolution time µs)(in duration recording •=

Fig. 10-34: Determining the recording duration

Parameterizing the Selection of Measured Values

For the oscilloscope function it is possible to select 4 signals that are

defined by the IDNs of their respective parameters and assigned to the

following parameters:

• P-0-0023, Oscilloscope: signal selection 1

• P-0-0024, Oscilloscope: signal selection 2

• P-0-0147, Oscilloscope: signal selection 3

• P-0-0148, Oscilloscope: signal selection 4

Only such parameter IDNs are allowed that are contained in the list

parameter P-0-0149, Oscilloscope: signal selection list.

Note: The selected signal (parameter IDN) defines the unit of the

data stored in the list of measured values.

Parameterizing the Trigger Function

See above "Trigger Function"

Parameterizing Time Resolution and Size of Memory

The recording range or the recording duration can be adjusted to the

measurement requirements via the following parameters:

• P-0-0031, Oscilloscope: time resolution

• P-0-0032, Oscilloscope: size of memory

The number of measured values is determined via P-0-0032,

Oscilloscope: size of memory. A maximum of 8192 measured values

per channel can be recorded for advanced design, a maximum of

4096 measured values for basic design.
