Analog value recording
Description
The "Analog Value Recording" function block can be used to record various
analog values (2 bytes/1word) in SIMOCODE pro over a set period of time.
For example, you can use this function block to record the characteristic
curve of the motor current when the motor is started.
Recording is carried out directly in SIMOCODE pro on the basis of the motor
feeder and independently of PROFIBUS or the automation system. Every
analog value present at the "Allocated analog value" analog socket is
recorded and saved. The recording starts on the basis of the edge (positive/
negative) via any binary signal at the trigger input of the function block. Up
to 60 values can be saved internally in the device. The time frame of the
recording is indirectly determined by the selected sampling rate:
Sampling time = sampling rate[s]
The pre-trigger can be used to specify how far in advance the recording
should commence before the trigger signal is issued. The pre-trigger is set
as a percentage of the entire sampling time. In addition, with
SIMOCODE ES you can also export the measured curve into a *.csv file for
further processing, for example, in MS Excel.

The old measured curve will be overwritten in SIMOCODE pro each time a
new trigger signal is sent to the trigger input.
