MELSEC-Q
3 WHEN COMMUNICATING WITH MELSECNET/H, MELSECNET/10
RELAY
(1) Transfer to Network No.
Designate the Network No. of the Ethernet or MELSECNET/H, MELSECNET/10
to which the communication request destination station or the communication
request source station is connected when sending a communication request
message or a response message, respectively.
(2) Intermediate Network No.
Designate the Network No. of the Ethernet or MELSECNET/H, MELSECNET/10
to which the next communication relay reception station or the next
communication relay transmission station is connected when sending a
communication request message or a response message, respectively.
(3) Intermediate station No.
Designate the station number of the target Ethernet module/network module that
is used as a relay to the network set by the Intermediate station No..
POINT
The following stations require the routing parameters to be set and registered:
1) The PLC CPU of the communication request source station
2) The PLC CPU of the stations (relay reception station and relay transmission
station) that relay communication request messages.
3) The PLC CPU of the stations (relay reception station and relay transmission
station) that relay response messages.
REMARK
(1) The routing parameters setting is not necessary for the other station access on
the same Ethernet network as the external device/local station QCPU.
(2) The routing parameters are designated in the following manner:
Transfer to Network
No.
Intermediate
Network No.
Intermediate
Station No.
To go to a station on the network No. , relay through the station No. , on the network No. , which is the first communication relay
from the local station.
(3) As an example, to perform other station access from station 1Ns3 to 3Ns4 in
the diagram in the next page, the following values are set to the stations which
require the routing parameter setting.
• Communication request source station : Station 1Ns3
• Communication relay station : Station 1Ns4/2Mp1, and Station
2Ns4/3Ns5
The code used for each station in the diagram indicates the Network No. of
the MELSECNET/H, MELSECNET/10 or Ethernet, station type, and station
number.
A maximum of 64 "transfer to Network No." can be set in the QCPU.
64 types of Network No. can be accessed to other station via local station or
can be the request source.
However, the same transfer destination Network No. cannot be set two or
more times. (multiple times)
