Routing Tables Section 7-3
Note 1. Version 1.20 of CX-Programmer must be used for the CQM1H-series Con-
troller Link Unit.
2. Use CX-Programmer version 2.04 or later for a CJ-series Controller Link
Unit.
7-3 Routing Tables
Routing tables that define the communications path from the Controller Link
Unit on the local PC to the network connected to the destination PC must be
created in order to send and receive data across networks. Each CPU Unit
implements the message service or remote programming/monitoring to the
appropriate Unit according to the routing tables.
Creating Routing Tables
Routing tables consists of a local network table and a relay network table.
Local Network Table A local network table provides unit numbers and network addresses corre-
sponding to the Units mounted to the PC.
Note 1. The unit number is set between 0 and 15 using the rotary switch on the
front panel of Controller Link Units for CS/CJ-series, CVM1, and CV-series
PCs, and is the same as the operating level for C200HX/HG/HE PCs. Set
operating level 0 for CQM1H-series Control Link Units.
2. The network address is the address of the network connected to the Unit
(between 1 and 127). The address is set when the local network table is
created.
Relay Network Table A relay network table provides the node and network addresses correspond-
ing to the initial relay point (first point the data must go to) en route to a target
network (end network) not directly connected to the local PC.
Note Remote programming and monitoring is possible from computer nodes.
