7.1 Selecting Points for Logging
In order for the data logging function of the EZT570S to operate, you must first select what variables
are to be logged to the data file. To choose which points are to be logged, select “Log Points” from
the Data menu. This screen allows the user to select any point(s) from the system for data logging.
Figure 7-1 Assign Log Points
Select the desired items from the list by turning each one on or off. Control loops offer PV, SP and
%Out selections while monitor points provide only the process value (PV) selection. When selections
are completed, press the “Save” button to save the point selection to memory. New selections will
not take effect until the Save button is pressed.
7.2 Start/Stop Data Logging
The EZT-570S logs data to its SD card. Current data for each variable is written to the log at a fixed
interval based on the settings entered in the “Length” and “Interval” fields. File names are
automatically generated using mm_dd_yyyy_hh_mm_ss format. To enter a new alphanumeric file
name, touch the “File Name” field and enter the desired value (up to 16 characters each). When a
file name is specified, the file will be saved as FileName_mm_dd_yyyy_hh_mm_ss.
