Collect data of external devices such as temperature controller and PLC into HMI s memory according to the conditions for period and device value. Basically logging is saved in SRAM (56KB) or CF card and back up in CF card or USB memory stick. It is possible to represent logged data into graph using recorder tag and extended graph tag. Also possible to convert into CSV format which can be used in PC so it is possible to analyze data in Microsoft Excel.

It is possible to represent the data values, which are saved through the logging function, and the files, which are saved in not only the inner memory, but also CF cards, in graph. It is possible to show the past information by use of a scroll switch only. It is possible to represent the cursor or the device value and the time the cursor is located. 4.

11 Use of CF card and USB memory 1. Effective use of CF card and USB memory It is possible to save PLC data in CF card or USB memory, inturn convert them into CSV data when necessary, and then, to make out a daily or a monthly document. (However, in the case of USB, it is possible to save PLC data only if data is copied from CF card.) It is possible to save picture, OS, or font files in CF card or USB memory, and then, to transmit to the HMI s memory. In case there are several HMI s, set-up is possible only by transmitting picture program to each HMI with a CF card or USB memory. Data management by File List 1. Data Management Tool for CF card and USB memory Copy data (logging, alarm, OS, fonts, screen program) to both CF card and USB in RUN mode Easy interface to data back up & operation by using USB memory & CF card Barcode reader and roll printer 1. Communication of Barcode reader and roll printer Save ASCII data, which is read from a barcode reader, in PLC designated by a user or HMI s inner memory (SRAM). It is possible to temporarily designate completion byte which can confirm that barcode data has been successfully read. It is possible to print data by connecting with the roll printer. The above connecting devices all use RS-C interface to communicate.
