User Define Mode - Delta Electronics IFD9506 Operation Manual

Ethernet Communication Module IFD9506
For example, if the station address of IFD9506 is 2, the IP address that station address 5 corresponds to
in the Serial Slave Mode table is 192.168.1.58, as shown in the following figure:
The following Modbus instructions are received in RTU mode.
1. "02 03 10 00 00 01 (80 F9)"
If the station address is 2, IFD9506 will respond to the instruction automatically.
2. "05 03 10 00 00 01 (81 4E)"
If the station address is 5, IFD9506 will convert the instruction into the Modbus TCP instruction and
then transmit it to the Ethernet equipment at the IP address 192.168.1.58.
Note:
The number of connections to the Ethernet server/ slave, which is established by IFD9506 cannot
exceed the upper limit of 16. If the limit is exceeded, IFD9506 will reject the connections. Therefore, it is
necessary to be aware of the number of connections to Ethernet server/ slave, and shorten the
connection-alive time (Keep Alive Time) in DCISoft to avoid too many idle connections. For timer
parameter setting, please refer to Section 6.6 Timer Setting.

6.4 User Define Mode

The User Define mode can be used for all of the three configuration modes:
1. In serial master mode:
Specify the listen port number for IFD9506 in the communication port (RS-232 or RS-485) field on the
User Define page of DCISoft. IFD9506 is Ethernet Server (slave) and the Ethernet equipment is
Ethernet Client (master). The Ethernet equipment needs to actively establish the connection to
IFD9506 through the port number.
