How to control FR-E800-E by iQ-R over CC-Link IE Field Basic

How to control FR-E800-E by iQ-R over CC-Link IE Field Basic

This article how to set up CC-Link IE Field Basic 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 FR-800 parameters through the network. 


Inverter setup

In case of FR-E800-_(SC)EPA/(SC)EPB CC-link IE Field Basic Communication have to be defined in one of parameters 1434-1437. CC-Link IE Field Basic can’t be used in the same time with CC-Link IE TSN so recommended is to change value of parameter 1429 from 45238 (CC-Link IE TSN) to 61450 (CC-Link IE Filed Basic).

 

To assign expected IP address of the inverter use parameters 1434 – 1437 or dedicated tool in FR Configurator2 (menu Tool >> Ethernet parameter setting).


It is also necessary to define range of IP addresses that will control inverter.


In case of CC-Link IE Field Basic it is possible to define map of refreshed data through communication. Value recommended for parameter 544 is 18.


Network configuration

Sample project with network configuration you can find in attachments to this article.

Setup communication parameters of built-in Ethernet port as described below.

IP Address/Subnet Mask– set IP Address and Subnet Mask of CPU module

CC-Link IEF Basic Settings

To Use or Not to Use CC-Link IEF Basic Setting –> Use – activates CC-Link IEF Basic Communication

Network Configuration Settings – setup network configuration
Add inverter from Module List on the right site of the window. Set up IP Address of inverter and Subnet Mask.

Refresh Setting – Setup auto-refresh devices

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 and 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.

FR_E800_R_CCLIE_Status - reading inverter status

This function block reads current status of inverter like status of terminal, output frequency and output current.

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.
