Introduction

<translate>

...Beckhoff Technical help is available on 01491 410539 option 3

{

Étape 1 - Install Visual Studio (if required)

...This now applies to all installations. The "CNC" standard PCs used for the front end on Flowlines and ZXs have Visual Studio already installed but the TwinCAt version needs to be upgraded from 4022 to 4024

1. Copy the install file from g:\Design\TwinCAT3\TC31-Full-Setup.3.1.4024.7.exe to the desktop of the Beckhoff PC
2. Delete the setup zip file and unzipped directory to save hard drive space

Étape 2 - Add the latest Device Description Table

Copy the contents of g:\design\twincat3\Beckhoff_EtherCAT_XML.zip

to

C:\TwinCAT\3.1\config\Io\EtherCAT and overwrite all the .xml files in this folder

...This allows the Beckhoff system to identify the latest version of the AX8000 drives

Étape 3 - Add Drive Manager 2 for AX8000 drives (if not installed already)

...This step needs to be done for the AX8000 drives only

1. Copy the Drive Manager 2 setup g:\design\TwinCAT3\TE5950-TC3-Drive-Manager-2.zip to Install Files or the desktop on the PC running Visual Studio
2. Close Visual Studio if it is open
3. Extract the Zip File
4. Run the Setup File
5. Delete the setup zip file and unzipped directory to save hard drive space

Étape 4 - Start a new project

1. Open Visual Studio
2. Click on New project
3. Choose TwinCAT projects->TwinCAT XAE Project (xml format)
4. Name is build number (no Suffix)
5. Location is c:\TwinCAT\Stuga\
6. Untick "Create Directory for solution"
7. This may take some time - a long delay sometimes "Rebuilding Device Description Cache"

...This creates an empty template to build your project for the machine

Étape 5 - Clone the Repository

...A Repositiory or "Repo" is a storage area for the source code versioning system. In our case we use an online system called "bitbucket"

1. Open Team Explorer
2. Clone a new Git Repository
3. URL to clone: https://bitbucket.org/StugaMachinery/tc3Multi
4. Click on the destination setup
5. Create a new folder under the machine build folder called "source"
6. Click 'Clone'

Étape 6 - Enter Git Credentials (if required)

Atlassian Username is StugaMachinery

Password is stored in the file

G:\IT Department\SourceTree BitBucket App Password.txt

...Sometimes, the password credentials are already stored and the password entry is not necessary

Étape 7 - Add The tc3Multi then PLC_Reset Project

1. Right click PLC
2. Select Add Existing Item
3. Navigate to the repository you have created in Step 6 c:\TwinCAT\Stuga\BuildNo\source\tc3Multi\tc3Multi.plcproj
4. Repeat for the PLC_Reset project

Étape 8 - Check PLC Ports 851 and 852 correct

Check that

tcMulti - Port 851

PLC_Reset - Port 852

If not you can change the port assignment by right clicking the PLC project - you will need to change one to a "spare" port 853 first

Étape 9 - Ensure Correct Machine Commented in tcMulti project

1. Navigate to tcMulti project->POUs->MAIN
2. Scroll down to the machine types. The "comment State" can be toggled on and off by right clicking next to the step number on the left
3. Your goal is to ensure the correct machine is highlighted and the incorrect ones are commented out (in green)
4. Click Save All

...Check the date next to the machine types - you will want the latest one

Étape 10 - Add TwinSAFE project

...From Z071 there is no twinSAFE project as the Estop circuit is hard wired

Étape 11 - Add the route to the Target System

If the front and back end PLCs are the same, the Target System is <Local>

If this is a separate Front End PC

1. From Dropdown box select the Build number (If it does not exist we will need to add a new route)
2. If there is a request for a platform change, click Yes
3. On success, the Route dropdown will not read Error

Étape 12 - Scan for Devices

1. Expand IO
2. Right click on devices, Scan
3. Click OK on the Hint:
4. Untick RT-Ethernet
5. Untick COM-Port
6. Just have the EtherCAT ports
7. Scan for boxes - Yes
8. If there is a request for New Device Type, Click Apply to All, Click Yes

If the scan does not work, a potential root casue could be missing EtherCAT drivers for the network adapter. See Updating Realtime Drivers for EtherCAT

Étape 13 - Check EtherCAT validity

Check the Devices and boxes match the expected EtherCAT setup

...Check the green lights on the etherCAT boxes for connection status. Flickering Green means it is OK

Repeat steps 7 and 8 until the physical network matches the scanned network

You may need to Right Click->scan Boxes on the second device if the EtherCAT boxes do not appear

...If the boxes do not appear in the right order, there could be an EtherCAT In /Out crossover

Étape 14 - Name all EtherCAT devices according to network

...Do not start this step until the EtherCAT network is fully verified. You will waste a lot of time if you ignore this!

Click twice on each device (not double click) to enable the device to be renamed

rename to convention

Étape 15 - Map all IO References

Using the circuit diagrams, map all the IO ref numbers to the associated IO channels

1. Double click a field-bus box or slice
2. Ensure you can see the input / Output list (may need some screen resizing
3. Double click an IO channel
4. Enter the number in the search box
5. Double click the associated IO Ref number from ibInputArray(inputs) or qbOutputArray(outputs)

...Click Save All regularly so you do not loose progress, as this process can take a considerable time

...Be very vigilant and ensure you only click on ibInputArray or qbOutputArray

Repeat for all IO

Étape 16 - Map Analogue Input references

Length and width sensors need to be mapped to their relevant EtherCAT boxes

• Width Sensor on Machining centre is iAnalogueInputArray[0]
• Length Sensor on Infeed table is iAnalogueInputArray[1]

Étape 17 - Double check all IO references with someone else

Any mistakes made will save hours if spotted here

Étape 18 - Install Drive Manager 2 Project

Étape 19 - Add Axis Task

A smooth setup will have detected the axes and added them under the MOTION tab already.

if not, an axis task may need to be added under the MOTION tree:

1. Add New Item
2. NC/PTP Configuration
3. Leave the Name as default

Étape 20 - Add Axes

Étape 21 - Map Axes

Étape 22 - Add PLC_Reset to tc3Multi Link

Étape 23 - Activate configuration

Étape 24 - Set up Drives

Étape 25 - Add The PC types to Monday Log
