■Table Conversion System
This system uses the network number, station number, IP address set in the conversion table of the Network/Station number
<-> IP information. The UDP port number predefined for the Ethernet-equipped module is used as the UDP port number of the
destination.
If duplicate network and station numbers are set in the conversion table, the data set with the younger registration number is
used.
If no data is registered in the conversion table, communication may not be performed successfully.
Conversion processing of the table conversion system is as below.
• When a communication request message (command frame) to access other station is received, the same network number
and station number are searched in the conversion table of the Network/Station No. <-> IP information, and the
communication request message is sent to the destination station with the corresponding IP address.
• The response message (response) for the communication request message is returned based on the return IP address and
the data in the conversion table above.
