■Communications by network number/station number by using the CPU module (built-in
Ethernet port part)
• The UDP/IP protocol is used for the connection and data is always exchanged as binary codes.
• When accessing another station, set the network number for the CPU module (built-in Ethernet port part) so that it is unique
among the network numbers of the other network. Also, set the station number that is unique among the station numbers
set for the other modules on the same network.
• When configuring the target station or relay station as a multiple CPU system, ensure that the CPU modules listed below
have the firmware supporting the communications by network number/station number.
• Target station
• CPU modules working as the relay path
• CPU module that controls the Ethernet module working as the relay path
USB
When communicating with CPU module shown as (1), ensure that all CPU modules have the firmware of the version supporting the communications by network
number/station number. Also, set the network number and station number to all CPU modules.
USB
When communicating with CPU module shown as (2), ensure also that all CPU modules have the firmware of the version supporting the communications by
network number/station number. Note, however, that the communication is possible even when the network number and station number are not set to CPU
module shown as (3) of the CPU No. 2.
