Address Conversion (when Using FINS Communications Service Only)
When using the FINS communications service, nodes must be specified following the FINS
addressing system. Data that is transmitted on the Ethernet network using FINS communica-
tions, however, must follow the IP address format. Address conversion changes the FINS ad-
dress to an IP address.

There are three methods for converting addresses, as follows:
•
Automatic generation method (default address conversion)
•
IP address table method
•
IP table + automatic generation method
All of these address conversion methods are performed from the system settings using the
Support Software (CX-Programmer, SYSMAC-CPT, SYSMAC Support Software, or CV Port
Software Ver.2 or later). The details for each method are explained below. Refer to the
SYS-
MAC CS/CJ Series Ethernet Unit Operation Manual
(Cat. No. W343) and the
SYSMAC
CVM1/CV Series Ethernet Unit Operation Manual
(Cat. No. W242) for details on setting
methods.
Automatic Generation Method
The automatic generation method uses the FINS node number without modification as the
host ID of the IP address. The net ID of the local IP address is used as the net ID.
Automatic generation uses the following type of remote IP address configured from the local
IP address, subnet mask, and remote node number (FINS node number).
Remote IP address = (Local IP Address AND subnet mask)
OR remote node number
•
Automatic Generation Characteristics
Automatic generation has the advantage of easily understandable handling of FINS ad-
dresses and IP addresses. This method, however, does have the following limitations.
1. This method is applicable for addresses with the same net ID only.
2. The remote host ID is restricted to the range of FINS node numbers (1 to 126) (See
note.).
3. The Ethernet Unit’s host ID and node number must be set to the same value.
Automatic generation is set as the default address conversion method, so it does not
need to be set from the CX-Programmer.
Note
: Up to 98 hosts can be set on the CX-Designer.
