Chapter 6 High-speed Link
6.1 Introduction
High-speed link (HS Link) is a communication method between XGT PLC communication modules to send and receive data
with HS link parameters setting, which can also allow the user to use XG-PD to exchange data with parameters setting of Tx/Rx
data size, Tx/Rx period, Tx/Rx area and area to save through its data transmission service function.
However, since HS link service uses the subnet broad service, it may have an influence on other communication modules which
use the identical network. Thus, setting as near to the max. Tx/Rx size (200 words) as available per HS link block is
recommended for the user to obtain the greatest communication efficiency with the lowest influence on other modules so to
reduce the sum of blocks.
HS link functions are as specified below;
(1) HS link block setting function
(a) If there are many Tx/Rx areas, up to 96 blocks can be set (32 for Tx and 64 for Rx respectively).
(b) 200 words are available for a block.
(c) Max. link points available are 19,200 words.
(2) Tx/Rx period setting function
Tx/Rx period can be set per block by user for the areas where especially fast Tx/Rx is required and not required
respectively in a Tx/Rx period of 20ms to 10 sec.
(3) Tx/Rx area setting function
Tx/Rx area can be set per data block by user according to I/O address specified.
(4) Providing function of HS link information
Reliable communication system can be easily configured by providing HS link information for user via the user keyword.
[Table 6.1.1] shows communication HS link points whose basic unit is 1 word.
