Maintenance Functions; Data Input/Output Function - Mitsubishi Electric MELDAS C6 Instruction Manual

9. Maintenance Functions

The machining programs, parameters and tool data, etc., are saved in the memory. However, these
contents could be lost due to the battery life, etc. To avoid total loss, save the machining programs,
tool data and parameters in an input/output device.

9.1 Data Input/Output Function

The data can be collectively input/output or collated in the data input/output screen or ATA card
in/out screen. This function can be used to protect data and investigate failure causes at the
customer premises. It can handle three types of data shown below. Hex data is converted and
output in the ISO/EIA format. Individual data items can also be input/output or collated separately.
This function is valid only while the user PLC is halted.
(1) Table data: The data area is reserved in advance.
(2) File data: The file format is required before data input.
(3) PLC program data: PLC program area data
