8. 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.
8.1 Data Input/Output Function
The data can be collectively input/output or collated in the data input/output 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.
Parameter (system, common, axis, machine error)
PLC data (PLC timer, PLC counter, PLC constants, bit selection, ATC data, axis control)
Work offset data
Backup data (PLC latch relay, PLC switch, program No.)
2. File data: The file format is required before data input.
Tool offset data
Common variables
Tool life control data
3. PLC program data: PLC program area data
