Hej Lesley,
Out from the distance it is impossible to see what is wrong,
given the information I have.
_ The key for failing can be seen in this line:

_2023-11-24T19:33:57+0800 Info:connection closed by remote _
And out of my experience, it may be a missing ADS route.
Or a typo somewhere, so that you think that everything is
good, but the PLC does not (and closes the connection)

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 1

Add device port: 0x851
_Add device notification failed with: 1861 _
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 ?)

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.
