5.1.2 Memory space required for data transfer
The extended function OS, monitor data and special data are transferred to the built-in memory of the
GOT. If the built-in memory does not have sufficient space, the data cannot be transferred.
Check the built-in memory space and the transfer data size before transfer of the data.
Remark
Check method of memory space
(1) New data transfer (No data has been transferred to the GOT.)
Check the total count equivalent to the required memories for installation of
the extended function OS.
Section 5.1.1
(1) Combination of extended function OS
that can be installed
Check the GOT built-in memory size used by the extended function OS
from the total count equivalent to the required memories.
Section 5.1.1
(2) Relation between extended function OS
and built-in memory
Check the size of the monitor data or the special data to be downloaded.
in this section Check method of transfer data size
Extended function OS + Monitor data + Special data size < Remaining
memory size of GOT
Installation is allowed.
Extended function OS + Monitor data + Special data size > Remaining
memory size of GOT
Installation is not allowed.
Ex.) GOT memory size
: 1152 KB (without memory board)
Count equivalent to memories
of extended function OS
: 3 (640 KB)
Monitor data
: 300 KB
Special data
: 26 KB
640 + 300 + 26 < 1152
Installation is allowed.
(2) Data has already been transferred to the GOT.
Check the built-in memory.
in this section Check method of GOT space
Check the monitor data size or the special data size to be added.
in this section Check method of transfer data size
Monitor data + special data size < Remaining memory size of GOT
Installation is allowed.
Monitor data + special data size > Remaining memory size of GOT
Installation is not allowed.
