12.1 Transient Transmission Function
12.1.2 Routing function
12.1.2 Routing function
The routing function allows the transient transmission to a station located on another
network number in a multiple network system.
In order to execute the routing function, it is necessary to set the "routing parameters" to
associate the network number of the request source and the station that functions as a
relay station.
The following is the precautions on setting routing parameters.
(1) Transient transmission range
Communication can be made with a station on the eighth farthest network system.
(No. of relay stations: 7)
(2) Access conditions when the station number of request source, request
target or relay station of the CC-Link IE Controller Network is 65 or higher
1) When the station number of the request source or request target is 65 or higher
Accessible with the following conditions
• The request source and request target are the Universal model QCPUs or
CC-Link IE Controller Network board.
• The relay station of the CC-Link IE Controller Network is the Universal
model QCPU.
2) When the relay station number of the CC-Link IE Controller Network is 65 or higher
Accessible with the following conditions
• The request source is the Universal model QCPU or CC-Link IE Controller
Network board.
• The relay station of the CC-Link IE Controller Network is the Universal
model QCPU.
POINT
The CC-Link IE Controller Network board cannot be used as a relay station. Use the
network module connected to the programmable controller CPU for the relay station.
