Modbus over Ethernet
AN-X-PBSLV supports Modbus over Ethernet. OPC/DDE servers that
support Modbus over Ethernet can communicate with AN-X-PBSLV to
read and write PROFIBUS node data.
The data for each node is accessed by setting the Unit ID to the
PROFIBUS node number.
For each node, PROFIBUS data is mapped to 0xxxxx, 1xxxxx, 3xxxxx,
and 4xxxxx registers. To view the mapping, use the web interface and
select Automation Network/View Active Configuration.
