5 USER GUIDE
[Function]
• When the node having a specified node number is to be subjected to common memory
transfer, an offset size will be reported to the FL.NET module.
• If the specified node number coincides with the self-node number, a parameter error
occurs.
• If the maximum size (0x200) of common memory area 1 is exceeded by the offset size
specified for common memory area 1, a parameter error occurs.
• If the maximum size (0x2000) of common memory area 2 is exceeded by the offset size
specified for common memory area 2, a parameter error occurs.
• If you specify the offset size during message processing, a "message processing already in
progress" error occurs.
When an offset size is specified for a specific node number, it is stored in
memory until the FL.NET module is turned OFF or reset. Note, however, that
the user cannot reference the offset setting within the FL.NET module after
completion of offset setup. The offset setting must be managed by the user.
The above feature is designed for use in cases where the available memory
space of the S10V is insufficient. It is recommended that you do not use the
feature when the memory space of the S10V is adequate.
When the address limit of common memory area 1 or 2 is exceeded by the
application of an offset, the resulting excess portion of address data will not
transfer to the S10V memory. Exercise care not to exceed the limits of the
common memory areas.
