Hi Guido, The subscription feature for Siemens plcs is currently in the oven, I can safely support you in that regard.
If you have a hybrid architecture, with S7-300 and S7-1500 (1200) devices, it is important to point out that the new S7-1500 series only supports a subset of the features of the S7-300, so it does not include the possibility of reeralize S7 subscriptions. In summary, the S7-1200 & S7-1500 only support PUT / GET. Currently the variable and alarm subscription is functional for the S7-300, S7-400. For the VIPA and Sinamics G120PN equipment (and other drivers) I hope to have the equipment soon. In [1] you can find an example code for the subscription process. (It's testing code!) In [2] you will find the development branch which I hope to request the PR shortly. But eventually you can test the subscription and other new features. I am dedicating to finalize the alarm processor and carry out tests to continue with the documentation, so any feedback from you is welcome. Best regards, 1. https://github.com/glcj/PLC4XS7ExamplesV9/blob/master/src/main/java/com/ceos/plc4x/s7/PLCAlarmAck.java 2. https://github.com/glcj/plc4x/tree/s7szl El jue, 4 nov 2021 a las 6:06, Rennert, Guido (<guido.renn...@koehl-mb.eu>) escribió: > Hello, > > > > as a complete newbie in Java, S7 and PLC4X it does not help - if I have to > get some data from a Siemens-PLC.
