Relay Function
Relay Function
A wireless slave station can be used as a relay station when expansion of the
communication area is intended but the direct communication is blocked by
obstacles.
The relay station can select either (1) the mode that does not connect the
DeviceNet slave (dedicated relay station mode) or (2) the mode functions as
both the DeviceNet master and the relay station by connecting the DeviceNet
slave (non-dedicated mode) using DIP switches.
For details, refer to 4-2 DeviceNet Wireless Slave Station Specifications.
The maximum number of relay stages is 3 (no. of hops: 4).
A configurator is used for the relay station system setting. When the wireless
slave station is used in the dedicated relay station mode, the DeviceNet slave
is not connected. However, since the communication power supply is
required, the communication cable needs to be connected.
Also, in the relay station system, the WCH switches of all wireless units must
be set to an identical frequency.
The I/O connected with wireless slave stations are loaded first by ascending
order of DeviceNet node addresses in the wireless slave station, and then by
ascending order of wireless node addresses for the slave station (WNODE) in
the wireless master station.
