Real-time Ethernet port multiplier62
Version: 2.6
Advanced Settings:
• "ARP Retry Interval": In order to ascertain the presence of the recipient, the publisher sends an ARP
request to the target device at these intervals. If the network administration of the recipient is
operational, it sends an ARP reply. This is only meaningful with unicast.
In the event of an error bit 3 is set (0x0004) in the diagnostic FrameState variable.
Note: ARP handling (ARP = Address Resolution Protocol: allocation of hardware/MAC addresses to
network addresses [IP]) is managed by the operating system (Windows).
• "Disable Subscriber Monitoring": Deactivates the procedure described above
• "Target Address changeable": In this case the destination IP can be changed dynamically
