PART 2: CX-Server PLC Tools
CHAPTER 10 – Data Links
Automatically Set Data Links
This section explains how to make the settings for automatically set data links.
Make the settings in the Automatic Datalink (Controller Link) or Automatic Datalink (SYSMAC LINK) dialog
box.
First make the settings for data link operation at PLC startup, and for the automatic data link setup parameters, and
then transfer the data to the startup node.
When using automatically set data links, there is no need to create data link tables with the Data Link Editor.
Procedure Through Data Link Startup
Create a CX-Server file (*.CDM) for connecting online.
1) Select New from the Project menu and save the setting under a file name.
2) Select Add Device from the Project menu, and register the PLC (as a node on the
network).
Connect online to the startup node PLC (registered as a node on the network).
(Select the startup node PLC and then select PLC | Open from the CX-Net.)
Set the automatic data link setup parameters.
1) Select Data Link | Setup.
2) Select Controller Link Unit or SYSMAC LINK Unit as the Communications Unit
mounted to the PLC. (For the local network only, i.e. when the network address is 0.)
3) Select PLC | Setup in the Datalink Component window.
4) Select Automatic in the Generation Type field in the Automatic Datalink dialog box,
and make the settings for the automatically set data link areas (start word, size, and
nodes participating in data links, for Area 1 and Area 2).
4) To have the data links started when
the PLC is started, set Start for the
status at startup.
Transfer the automatic data link setup parameters to the startup node. (Click the
Write button.)
Turn ON the power to the PLC.
