4-12 CX-Programmer Procedures
This section describes the procedures from creation of data link tables to
starting up data links using CX-Net in CX-Programmer.
Here, the procedure for CX-Net in CX-Programmer Ver. 1.2 (Service Pack 1)
is given as an example. The operations, windows, and setting items may vary
with the version of CX-Programmer.
4-12-1 Overall Procedure
If building SYSMAC LINK data links for the first time, make the settings using
the following procedure. It is necessary to create data link tables if using man-
ually set data links.
Note There is no need to create data link tables when using automatic settings. If
using automatically set data links, set the DM parameter areas (DM area
words allocated to the SYSMAC LINK Unit as a CPU Bus Unit) using a Pro-
gramming Console or the PLC Memory Window in CX-Programmer.
1,2,3... 1. Start CX-Net from the CX-Programmer by selecting Tools and then Net-
work Configuration Tool .
2. Open the CX-Server file (*.CDM) in CX-Net or create a new file in CX-Net
by selecting
Project and then Open in CX-Net.
3. Start the Data Link Editor to create the data link tables by selecting Data
Link and then Editor .
• If creating the same data link tables in all nodes, start the Data Link
Engineer from the Data Link Editor by selecting Table and then Data
Link Engineer .
• If creating different data link tables for each node, create data link pa-
rameters for each node by editing tables for each node individually.
