Relay station
A station that relays the transient transmission to other networks.
A station which transfers a link device of a network module to other network modules.
Multiple network modules are mounted on a base unit.
Reserved station
A station reserved for future use. This station is not actually connected, but counted as a connected
station.

If the target stations for the transient transmission are specified as a group, data can be sent to the stations
in the same group.
Cyclic transmission
A function that periodically exchanges data between the remote master station and remote I/O stations
using the link device LB, LW, LX, or LY of a network module
Device A device (X, Y, M, or D) in a CPU module or MELSECNET/H remote I/O module
Transient transmission
A function of communication with a programmable controller in other stations, which is used when
requested a link dedicated instruction or peripherals.
This function can communicate with a programmable controller on the same network and other networks.
Buffer memory
A memory in an intelligent function module and special function module to store data temporary.
The MELSECNET/10 remote master module does not have any buffer memory area that users can use.
