The register/extension memory address range applicable to the higher layer
status area and FA link status area is the same as for the CPU or LPU
memory allocation area.
When the higher layer status area is set up, the contents of the higher layer
status flag are transferred as 1-word data.
When the FA link status area is set up, the contents of the FA link status flag
for the node are transferred to the low-order byte of the specified area.
The higher layer status/FA link status area setting must not be a duplicate of
the CPU or LPU memory allocation area setting for a remote node (reception
setting) or the self-node or of the setting for any other area.
If any node is omitted from the node settings given, the FL.NET module
cannot transfer the higher layer status or FA link status of that node to the
S10mini or S10V.
5.4.3 Using bit data
The FL.NET module subjects the common memory area 1 data to bit conversion at the time of
transmission/reception.
