Chapter 5 Data Log Function
5.1 Overview
XGB PLC comes with built-in data log function. This chapter describes the specifications and usage of the data log function.
5.1.1 Features
Using the high-performance XGB internal data log function, you can collect run data of PLC 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 PLC Device Data Saving
You can save PLC’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 each scan, 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 16GB SDHC memory card, which allows for saving run data over a long period of time
(4) FTP Interface
Files saved in the data log can be read remotely using FTP, making it easier to verify data fluctuations.
