17.4 IPv4SET (IP Address Setting)
■
Ladder diagram
(Note 1) The above figure shows the case that S1=U100 (built-in ET-LAN in the CPU unit) and S2=U1
(connection number 1) are specified by the UNITSEL instruction.
(Note 2) By copying and pasting the following text in the instruction list box of FPWIN GR7, the operand part of
the above program can be input.
IPv4SET “IP=192.168.1.5, MASK=255.255.255.0, GWIP=192.168.1.1”

Outline of operation
This instruction configures the IP (IPv4) address setting.
■
Processing
● The IPv4 setting parameter for [S] is stored in the operation work area, and the IP address
(required), the subnet mask (optional), and the gateway (optional) of the Ethernet unit are
initialized. Values specified by tool software are applied to items that are not modified by
instructions.
● Communication is not available while Ethernet initialization is in progress.
● Statuses such as the establishment of IPv4 address or cable disconnection can be checked
in the input relay area WX6 (X60 to X69).
● For details of the input relay area WX6, refer to "19.10 Ethernet Function: IP Addresses".
