2) The transfer data is sent to the transfer to network via the network module; it is
not stored in the transfer to device range of the network module.
When using the transfer data in the relay station, the transfer to data must be
transferred to the device on the CPU side by link refreshing.
POINT
When it is necessary to set 65 or more transfer ranges for the inter-link data
transfer function, the data must be transferred from the transfer from to the
destination in the sequence programs using the MOV instruction, etc.
