Setting Data Link Tables

To perform data links, data link tables are required. Set data link tables by following the steps

below.

1. Set data link tables using the CX-Net (Network Configurations Tool).

Data link tables are created to define data links. These tables must be set for each node

participating in data links. Refer to the manual for CX-Programmer for the method of set-

ting.

The following table shows the items and setting range for data link tables in the Control-

ler Link Support Board mounted on the PT.

Setting item Setting range

PT Model Set as a "NSB."

Node 1 to 32

Set the address of the refresh nodes.

First data link status

word

If a number is set, it will be invalid because the first word to store data link

status is fixed.

Set ”-“.

Area 1 Data link

start word

(See note.)

$B0 to $B32767

$W0 to $W24575

Use CIO for $B and D for $W in the CX-Net.

The same area cannot be set for both area 1 and area 2. Set different areas.

Number of

words

• Remote nodes: 0 to the number of source words

Set the number of words to be received

• Local nodes: 0 to 1000

Set the number of words to be transmitted

The total number of words in area 1 and area 2 in each node must not exceed

1,000.

The number of words in both area 1 and area 2 in each node must not be set

to 0.

Offset • Remote nodes: 0 to one less than number of source words

Set offset for data to be received

• Local nodes: Cannot be set.

This setting is not required if an offset is not used.
