Accessible routes
(1)
Own station (control CPU, another
CPU in a multiple CPU system)
(2)
Another station via single network
(3)
Another station via co-existence
network
Precautions
If the load on the network is high, data may not be processed in a device on the access route (including an access target CPU
module) and an error such as a timeout may occur. Do not use a high speed data communication module in the overloaded
network conditions.
: Connection with an Ethernet
port of a high speed data communication
module

Own station (control CPU, another CPU in a multiple CPU system).
Access from an Ethernet port of a high speed data communication
module.
Access by specifying the network number and the station number of a
target station.
Access by specifying the start I/O number of a module and the station
number of a target station for accessing the target station.
Access from the station accessed in by specifying the network
number and the station number of the target station.
Access from the station accessed in by specifying the start I/O
number and the station number of the target station.
: Connection by specifying
the network number and the station
number of a target station in each
module
