10-2-5 Procedure for Changing the Data Link Tables with CX- Programmer

The procedure for changing a data link table with active data links is shown here using CX-Programmer version 3.2 and the following system configura- tion.

Node 1 Node 2 Node 3		Node 4
	CS1W-RPT01	Newly added node
	Repeater Unit

Data Link Area

Node 1 Node 2 Node 3 Node 4

The table contents are as follows: Area 1: DM Area

First word: DM 00000

Send and receive words: 10 words each

In this example, by adding node 4 to the network, the receive area from node 4 is added to the data link table of node 1.

!Caution Check that the contents of the data link table to be changed are correct for the corresponding node before changing them. If an incorrect data link table is set, the unexpected operation of the system may result in injury.

Note 1. Check that the contents of the data link table to be changed will be appro- priate for the corresponding node. If the data link table is set with inappro- priate data, the Unit may operate abnormally and cause injury.

2.Check that the effects of the data link table to be changed has been con- sidered in the user programs before changing a data link table.

3.CX-Programmer version 3.2 or higher must be used to change a data link table with active data links. CX-Programmer version 3.1 or lower versions cannot be used.

Procedure

1,2,3... 1. Create the new data link table to be transferred to the node whose data link table is to be changed (node 1) offline.

2.Save the created data link table in a file.

3.Connect the personal computer to CX-Net so that it is online.

4.Select Data Link − Setup from the Menu.

5.Open the data link table file saved in step 1.
