Setting Routing Tables Section 7-4
SIOU Unit No.:
Unit number of the Communications Unit (operating level for C200HX/HG/HE
PLCs; always 0 for CQM1H-series Units). (CS/CJ-series, CVM1, or CV-
series: 0 to 15, C200HX/HG/HE: 0, 1, CQM1H-series: 0) Set the unit number
of all Communications Units (SYSMAC NET Link Units, SYSMAC Link Units
and Controller Link Units) as well as the address of network connected to it.
Be sure to set the same address for each network when setting routing tables
(local and relay network tables) in multiple PLCs.
7-4-3 Editing Relay Network Tables
Use the routing table editing function on the Programming Device to edit the
local network table as shown on the screen given below.
End network:
Network address of the end network (1 through 127)
Relay network:
Network address of the first relay point on the way to the end network (1
through 127)
Relay node:
Node address of the first relay point on the way to the end network
(SYSMAC NET: 1 through 126, SYSMAC LINK: 1 through 62, and Controller
Link: 1 through 32 (1 through 62 when using a CS/CJ-series Unit (CS1W-
CLK21-V1 or CJ1W-CLK21-V1) with the Wired Network 62 Node Enable Bit
turned ON, or with an optical ring network), Ethernet: 1 through 126)
Set all networks not directly connected to the PLC.
Be sure to set the same address for each network when setting routing tables
(local and relay network tables) in multiple PLCs.
Note 1. Do not set the same end network more than once with the C200HX/HG/
HE or CQM1H-series PLCs. Routing may fail.
2. The PC ID is any unique name given to a specific node.
When setting the PC ID, simply input the ID. Network and node addresses
will be input for you automatically. See the operation manual for SYSMAC,
CV, or Controller Link Support Software for further details.
7-4-4 Saving Routing Tables
After editing local and relay network tables on the Programming Device, save
the tables.
Note When setting routing tables in multiple PLCs, edit and save all routing tables
and then transfer them together to work more efficiently.
