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

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.)
