Comment to the multicast settings
In the Multicast-Mode serial busmembers who are communicating with RS485 interfaces can be connected
via the (W)LAN. Depending which task the serial device takes it is possible to configure different modes:
1. Slave
2. Master
3. Multimaster
As a slave the WI-Client receives data on the configured multicast address and sends this data to the serial
interface. Data that is received from the serial line is sent to the given unicast IP address.
As a master the WI-Client receives data from the unicast IP address and transmits data to the multicast IP
address.
In multimaster mode all transfers are done via the multicast IP address.
