4.2 Difference between memories and logs

A memory contains all cumulative values from the start of the recording until the activity is manually completed on the SIGMA device. A new memory then starts. Most SIGMA devices have a memory. Some devices such as ROX 11.0 have several memories and can also record logs.

In the log, individual values are saved at specific intervals. The values are then displayed in the DATA CENTER evaluation as a graph. The memory capacity for the individual values depends on the log interval (see the device’s operating instructions).
