Fetching G-Code Program Files

The G-code program is stored in the standard ROM on the Motion CPU as a G-code program file. Refer to the following for
storage destinations in the standard ROM.
MELSEC iQ-R Motion Controller Programming Manual (Common)
The timing for fetching files is shown below.
• Multiple CPU system power supply ON
• Multiple CPU system reset
• STOPRUN

Fetching G-code program file during operation

During G-code program operation, programs can be updated (fetch G-code program file) without stopping the Motion CPU by
RUNSTOP. Fetch the program that is transferred to the fetching area during program operation in the Motion CPU.
Fetching G-code program files during operation can be executed using the following methods.
• G-code program operation in MT Developer2. (Page 91 G-code program operations with MT Developer2)
• GOT program input/output and GOT program editing. (Page 236 G-Code Program Operation by GOT)
• G-code program transmission by file transmission via FTP server. (Page 95 Fetching program file during operation
using file transmission via FTP server)
Cautions
• In the following cases, G-code program fetch fails. The causes and corrective action are shown below.
Error details and cause
When there was a G-code program fetch request during the operation of the
applicable program.
When there is an error in the G-code program file format.
When the G-code program size exceeds the size of the fetching area during
program operation.
When the specified program No. is outside of the range.
When program fetch during operation is requested during STOP.
• While executing program fetch, when the applicable G-code program is started, a minor error (error code: 1FC3H (details
code: 031FH)) occurs.

Corrective action
Check that the applicable G-code program is not in operation.
Correct the G-code program file format.
End G-code control, RUNSTOP, and fetch the G-code program again.
• Check "[Cd.3305] Program No. for loading while running (D54264)"
• Check the applicable program is stored in the "$MMTPRJ$/gcode/prog/
temp" folder in the standard ROM.
Do not request program fetch during operation during STOP. The program will
be fetched at STOPRUN by storing the program in the folder as usual.
