Poor performance
•
Right click ‘subnetwork’ in the Navigation window and

information about the subnetwork.
If the gateway reports very many retransmissions,
check your cabling and/or try a lower baud rate setting
for the subnetwork (if possible).

Is the Subnet Monitor in the Anybus Configuration
Manager active?
The subnetwork monitor has a negative influence on
the overall performance of the gateway, and should
only be used when necessary.

If no data is being transmitted, check the configuration
in Anybus Configuration Manager.
