Appendix 2 Automatic Update of System Software
The SPF series has the automatic update function of system software. To use a newly added expansion unit, front board or
functions, you need to update the SPF system software to the latest version using this function.
<Operation overview>
A loader supporting the SPF series stores the latest version of SPF system software.
It operates as follows when connected to the SPF series. Update the system software as needed.
(1) When displaying the “Control” dialog box on the loader, the system software version of the connected SPF and that of the
loader are automatically compared.
(2) If the system software version of the SPF is older than that of the loader, a screen appears prompting you to update it.
(3) Update the system software of the SPF following the procedure.
Notes:
1) During update, do not power off the SPF system and do not disconnect the loader cable.
2) Applications are not deleted even if the system software is updated. However, back them up in advance as needed. The
backup procedure is the same as “Main unit replacement procedure” described in 5-2. See “5-2 Actions to be Taken When
Battery Voltage Drop is Detected.”
3) Applications in operation will be stopped. Stop the system in advance as needed.
