This article how to set up CC-Link IE TSN connection between iQ-R PLC and FR-E800 inverter. It also presents ready to use function blocks to realize basic control, read inverter monitors as well as read and write E800 parameters through the network.

Inverter setup
In case of FR-E800-_(SC)EPA/(SC)EPB CC-link
IE TSN is a default communication protocol. It’s not necessary to change any of
the Inverter parameters to be able to control FR-E800 using CC-Link IE TSN. To
assign expected IP address of the inverter use parameters 1434 – 1437 or
dedicated tool in FR Configurator2 (menu Tool >> Ethernet parameter
setting).
Network configuration

Sample project with network configuration you can find in attachments to this article.
Setup communication parameters of CC-Link
IE TSN module as described below.
Station
No./IP Address Setting
– set IP Address of CC-Link
IE TSN master module
Network
Configuration Setting
– add slave devices
Use Connected/Disconnected Module Detection
button to detect connected devices or add inverter from Module List.

Refresh
Setting – Setup auto-refresh devices

Communication
Period Setting – set communication period and
system reservation time according to inverter requirements.

Connection
Device Information – allow to connect
Authentication Class A device to the network

Communication
speed – set communication speed to 100Mbps when all
connected devices are 100Mbps
Dedicated Function Blocks

Library files and sample project you can find in attachments to this article.
Library import
First of all user library have to be
registered. Select Register User Library… from Library tap of Element Selection
and browse library file.

Each FB in FR_E800_R_CLLIE_Lib library uses FR_E800_CCLink_data structure to pass data between FB registers
where data received from inverter are stored. It is necessary to define global
variable related to each inverter that will be controlled and assign correct
addresses to those variables based on refresh setting of CC-Link IE.
Function Blocks

Details of each function block you can find in attached documentation.
FR_E800_R_CCLIE_Control - basic inverter control
This function block performs
basic inverter control – start, set frequency, reset errors.
R_E800_R_CCLIE_Status - reading inverter status
This function block reads
basic status of inverter like status of terminal, output frequency and output
current.
FR_E800_R_CCLIE_Status - reading inverter status
This function block reads current status of inverter.
FR_E800_R_CCLIE_Monitor - reading inverter monitors
This function block reads monitors of inverter defined you user.
FR_E800_R_CCLIE_ParameterRead - reading parameter value
This function block reads value of specified by user parameter.
FR_E800_R_CCLIE_ParameterWrite - writing parameter value
This function block writes specified by user value to the specified parameter.
