Routing Tables Section 7-3
CX-Programmer
A CX-Programmer connected to a CS/CJ-series, C200HX/HG/HE, CVM1,
CV-series, or CQM1H-series CPU Unit can program and monitor any other
PLC on a different type of network (Ethernet, SYSMAC NET, or SYSMAC
LINK) through a CS/CJ-series, CVM1, or CV-series PLC.
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 higher 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 PLC to the network connected to the destination PLC 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 PLC.
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
PLCs, and is the same as the operating level for C200HX/HG/HE PLCs.
Set operating level 0 for CQM1H-series Control Link Units.
Note Remote programming and monitoring is possible from computer nodes.
