Bernhard Rupprecht commented on PLC4X-204:
------------------------------------------
Hi Chris,
thank you for the quick response.
I am a little confused. According to the documentation on the website
([https://plc4x.apache.org/users/protocols/s7.html),
|https://plc4x.apache.org/users/protocols/s7.html)]the S7 protocol does support
subscribing to values:
|{{subscribe}}|Generally supported with {{tcp}} transport with S7 devices of
types: {{S7 300}}, {{S7 400}}, {{S7 1500}} (active and passive). With
{{raw-socket}} and {{pcap-replay}} supported on all devices (passive).|
Are you referring to a different thing or is the described support not yet
implemented?
Kind regards,
Bernahrd
> S7 Connection: Subscribing not possible
> ---------------------------------------
>
> Key: PLC4X-204
> URL: https://issues.apache.org/jira/browse/PLC4X-204
> Project: Apache PLC4X
> Issue Type: Bug
> Components: Driver-S7
> Affects Versions: 0.7.0
> Reporter: Bernhard Rupprecht
> Priority: Major
> Attachments: LogProgramExecution.txt
>
>
> I established a connection to a S7-1500.
> Connecting, Reading and Writing works fine.
> However, its not possible to get the subscribing feature to work.
> The PLC access level is set to full access and the put/get communication is
> on.
> I tried several connection strings including:
> s7://192.168.16.150 or
> s7:tcp://192.168.16.150?controller-type=S7_1500&remote-rack=0&remote-slot=1
> However, the program always states that the connection does not support
> subscribing.
> As I am very new to working with PLC4X:
> Did I forget to configure/activate some options in the PLC settings or is
> this really a bug in the S7- driver?
> Attached is the log while executing my test application.
> Thank you very much for your adice. If nessecary, I would be happy to provide
> you additional information.
