Re: Beckhoff ADS to EPICS

Yes, I set up an ADS route on " another Beckhoff PLC " as follows.

First of all  I used BeckhoffADS module (https://github.com/EuropeanSpallationSource/epics-twincat-ads/BeckhoffADS)to test the connected PLC. I set up the new ADS route in the following file in this module.

BeckhoffADS/PLC-TestProject/NotificationTest.tsproj

BeckhoffADS/example/example.cpp

Then I execute make test and the following error occurs.

./example.bin

Running step 2

What is the cause of this error?

Also, for the IOC, I changed the AmsId and IP of another PLC in the file "startup/adsOnlyIO.cmd".

Hej Lesley,

 

Did you set up an ADS route on “another Beckhoff PLC “ (towards your IOC ?)

Subject: Beckhoff ADS to EPICS

 

Hello!

I previously used the EPICS Module to communicate with TwinCAT controllers over ADS protocol (https://github.com/EuropeanSpallationSource/epics-twincat-ads). The programme runs correctly.

  When I switched to another Beckhoff PLC, I then used BeckhoffADS module (https://github.com/EuropeanSpallationSource/epics-twincat-ads/BeckhoffADS)to test the connected PLC as follows:

 

# Authorise my ADS client for the TwinCAT target by adding an AMS route.

# Switching directories

cd example/

 

# build

make

 

# and run the example

make test

 

The following error occurs:

[newuser@localhost example]$ make test

./example.bin

What can I do to fix this?Thank you for your time.
