Chapter 11 Datalog Function
11.1 Overview
Motion controller comes with built-in datalog function. This chapter describes the specification and usage of the datalog
function.
11.1.1 Features
Using the motion controller internal datalog function, you can collect run data of motion controller and save them into a
SD memory card in the CSV (Comma-Separated Values) format just with a simple parameter configuration. The
function has the following features.
(1) Easy Motion Controller Device Data Saving
You can save motion controller’s various device data with just a simple parameter configuration. It eliminates the
need to construct a network to collect large volumes of run data, thereby saving system costs.
In addition, it eliminates problems that might be caused in network-based data collection, such as communication
cutoff or cable disconnection.
(2) Precise Data Collection
This function allows you to collect precise data for main task, by 1ms or in accordance with other various run
conditions.
In addition, you can use the trigger function to save data before/after the trigger. Or you can use the event function
to save data changes from the event occurrence. This allows for easy analysis of the system’s run status, which also
saves system maintenance costs.
(3) Large-volume Operation Data
The function supports up to 8GB SD memory card, which allows for saving run data over a long period of time
(4) FTP Interface
Files saved in the datalog can be read remotely using FTP, making it easier to verify data fluctuations.
