6. EtherNet/IP Settings
This section describes the specifications such as communication parameters and tag data link
that are defined in this document.
Hereinafter, the PLC is referred to as the "destination device" in some descriptions.
6.1. EtherNet/IP Communications Parameters
The communications parameters required to connect the Controller and the destination device
via EtherNet/IP are given below.
Controller (Node 1) PLC (Node 2)
IP address 192.168.250.1 192.168.250.2
Subnet mask 255.255.255.0 255.255.255.0
6.2. Allocating the Tag Data Links
The data in the tag data links of the destination device are allocated to the global variables of
the Controller. The relationship between the device data and the global variables is shown
below.
The following global variables are defined in the "Configuration file".
■Output area (Controller → PLC)

Additional Information
With the Sysmac Studio, two methods can be used to specify an array for a data type. After
specifying, (1) is converted to (2) and the data type is always displayed as (2).
(1)WORD[3]/(2)ARRAY[0..2]OF WORD
In this document, the data type is simplified by displaying WORD[3].
(The example above means a WORD data type with three array elements.)
