Chapter 5 High-speed Link Setting
5.1 Introduction
High-speed link specifies the Send/Receive device area and data size between CPU module and the
communication module by XG5000.
High-speed link can be set the function as shown below.
Description
High-speed Link
Communication
module
setting
Communication
module setting
Module type
Rnet
Base no.
Base number is only set 0.
Communication
period setting
(Period type)
Select among 20ms, 50ms, 100ms, 200ms, 500ms, 1s, 5s, 10s.
- Default setting: 200 ms
Output data setup
in case of
emergency
CPU error
Latch
Keep the previous output status.
Clear
Clear the output.
CPU stop
Latch
Keep the previous output status.
Clear
Clear the output.
Mode
Send : the data transfer from master module to slave module
Receive : the data transfer from slave module to master module
Communication
Method
The communication method between master and slave
Read area
(From Master to
Slave module)
Address
Head address of the sending device
Size
(Byte)
Input/Output point of slave module is displayed Byte.
- If input /Output module is less than 8 bit, it is processed 1 Byte.
Save area
(From Slave to
Master module)
Address
Head address of the receiving device
Size
(Byte)
Input/Output point of slave module is displayed in Byte.
- If input/Output module is less than 8 bit, it is dealt with 1 Byte.
PLC connection
RS-232C or USB Port of CPU module
Control condition
It can control regardless of position of Run mode switch (Run, Stop) of CPU module.
Max. communication point
3720 bytes (31 blocks * 120 bytes)
Max. block number
64 (Setting Range : 0~63)
Max. point per block
120bytes
Number of High-speed link
setting
Up to 2
1) When High-speed link is edited, parameter has to be downloaded again.
2) High-speed link is used per a communication module.
3) CPU module saves the written parameter (Standard, High-speed link, P2P).
4) When CPU module is exchanged, parameter in XG5000 should make backup and then the parameter
has to be downloaded in CPU module again.
5) Minimum communication cycle (20ms) doesn't be assured when two extension communication modules
are attached on main unit. It's because the main unit shares resource with two extension communication
modules. Thus, check communication load before setting high-speed link parameter.
