(6) Link special registers (SW)
The link special registers store the data link status using word data.
Buffer memory addresses 600
For details on the link special registers (SW0000 to SW01FF), refer to
(7) Random access buffer
The random access buffer stores any data to be sent to other stations.
The reading and writing of data are performed using transient transmission.
(8) Communication buffer
The communication buffers stores the send and receive data when performing transient transmission
(communication using the communication buffers) between the local stations, standby master station, and
intelligent device stations.
The communication buffer sizes for the local station, standby master station, and intelligent device station are set
with network parameters.
For how to set the communication buffer size settings, refer to
[Example of communication using the communication buffers]
