Overview

 

Within MCL-Designer V4, local files used in a project are designated as data files and can be found in the "Data Files" module. See Navigating the Data Files Module.

These files store the data input on a permanent basis in the device. They are created by the application inside the device. The device can receive data from the host and store it in these data files.

These files can be used as a reference file for input validation or as a guide for the operator.

MCL-Designer allows you to create commands (ex: to read, write, search, update, delete, etc.) to work with data files. See Working with the Data Files Processes Group.

 

 

Number and Size of Files

 

In MCL-Designer V4, the number of files that can be used in a project is directly related to the size of the files and the memory available in the device.

The maximum record size in data files is 64 KB (65.536 bytes). A record can contain up to 1.024 fields.
