CC-Link IEF Basic iQ-R and CR800

CC-Link IEF Basic iQ-R and iQ-F with robot FR series (CR800 controller)

This is a shortened version of Ethernet Function manual and it covers only IEF Basic communication setup between iQ-R and iQ-F PLC and one MELFA robot as a slave.
iQ-F settings describe in attachment.

These Function Blocks are demo versions that are only  intended to demonstrate program functions and provide general orientation for  your software choices. They are not suitable for use in real applications! "

"Improper use of demo versions in applications can lead to serious malfunctions  and damage! Programs for real applications must always be configured for the  individual application by trained staff and tested thoroughly before being  used.

Robot parameter settings

In RT Toolbox 3 set up Ethernet parameters in Online -->Parameter-->Communication Parameter -->Ethernet
Remember, that engineering station, PLC and the robot have to be in the same subnetwork

In RT Toolbox3 enable CC Link IEF Basic function in Online -->Parameter Field Network Parameter -->CC Link IE Field Basic
Picture 2. Enable CC Link IE Field BasicPicture 2. Enable CC Link IE Field Basic
Write the changes to the robot controller and restart it.

PLC parameter settings

In GX Works3 enable CC-Link IEF Basic function in Parameter -->RxxCPU --> Module Parameter Own Node Settings.  In order to do this, change 'To use or Not to Use CC Link IEF Basic Setting' to Enable.

Right-click on found module and change module to CC Link IEF Basic
Press Close with reflecting the setting --> Yes

Go to Refresh Settings and assign slave devices to PLC Devices.

Exemplary settings are shown in the picture above:
  1. RX0-RX63 Dec (RX0-RX3F Hex) is assigned to B0-B63 Dec (B0-B3F Hex)
  2. RY0-RY63 Dec (RY0-RY3F Hex) is assigned to B4096-B4159 Dec (B1000-B103F Hex)
  3. RWr0-RWr31 Dec (Rwr0-Rwr1F Hex) is assigned to W0-W31 Dec (W0-W1F Hex)
  4. RWw0-RWw31 Dec (RWw0-RWw1F Hex) is assigned to W4096-W4127 Dec (W1000-W101F Hex)
Apply the changes, go to Online and write them to PLC.

Diagnostics and application

In Diagnostics dropdown menu select CC Link IE Field Basic Diagnostics and check the connection.

Copy the programs attached to this guide and paste them to the respective devices. These programs are created to test the communication between the Robot and the PLC.
On the robot side, the program sets outputs of the robot to 1 with M_Out, then it sends words to CC-Link outputs with M_Dout
On the PLC side, the program reads these values and moves them to its own outputs – bits to bit outputs, words to word outputs.
Results of these programs cooperating are shown on the pictures below.
