Trigger Source (0x2370.01), Trace Source 1 to 4 (0x2370.07 to 0A)
The parameters to be recorded, Trace Source 1 to Trace Source 4, must be entered into the
objects 0x2370.07 to 0x2370.0A as pointers to a corresponding object entry (index and sub-
index of the desired parameter). The trigger source must be entered into the object
0x2370.01 as a pointer to a corresponding object entry (index and subindex of the desired
parameter).
Example:
The object 0x6064.00 (position actual value) must be recorded as the first data source: The
value 0x606400 must be entered into the object 0x2370.07.
Trigger Threshold (0x2370.02)
The trigger threshold is entered into object 0x2370.02.
Depending on the settings of bits 1 to 3 in the trigger type object 0x2370.04, recording is
started on the threshold set here being exceeded or undershot.
Trigger Delay Offset (0x2370.03)
The trigger delay is stated in object 0x2370.03 as a multiple of the sample time set in object
0x2370.06.
Delay > 0: Recording is started at a time defined as the set multiple times the sample
time.
Delay < 0: Negative delays can be performed up to the length of the buffer. Recording
ends at the point in the ring buffer where the recording for the current trigger would
have had to start. This ensures that the values recorded before the trigger are retained.
Trigger Mode (0x2370.04)
The trigger type and the type of the data sources are determined by the object 0x2370.04.
Bit 0 activates the trigger and thus providing the trigger conditions are satisfied starts the
recording.

Buffer Length (0x2370.05)
The length of the buffer (number of values) available for recording is set in object
0x2370.05. The permissible length is dependent on the data type and the number of the
parameters to be recorded. In total a maximum buffer of 4 kByte is available.
