Scope parameters
Scope parameters :
5 parameters for scope settings (Address 41..45).
80 read only parameters for the measuring values (Address 100..179).
Use of scope function
When a time scale different of 0 is written, the drive starts the measurement, the parameters
100..179 are filled cyclically with samples.
When trigger condition is satisfied, the drive saves the position (trigger position parameter) and
continues the measurement during the number of post-trig samples defined. At the end of the
measurements, time scale parameter is set to 0 to indicate the end.

Scope options
(since firmware
V2005)
bit 15 = 0 -+ saturation (when values overshoot with the defined
scale).
bit 15 = 1 -+ no saturation (for bit wise operations or low bits
watching)
