Integrate Siemens Logo (plclogo) in OpenHAB 2

[falkena (Alexander Falkenstern)]

Hi @Euphi,

thanks I’ll try to answer your questions:

@Euphi

• However, it took us some time to establish the connection. Problem was a missing S7 connection in the Logo configuration. The documentation should give a short hint, how to create the connection with LogoSoft Comfort.

Well, the procedure is well described in manual to LogoSoftComfort: simply search for “network project” and/or “ethernet connections”. An Pull-Request with updated documentation is also welcome.

@Euphi

• What exactly is a pulse thing? After reading the binding’s documentation and this thread, I still don’t get it. It seems that this is a way to generate a Pulse if some other Variable (Block) has changed.

I’ve added some lines to documentation

@Euphi

• Why do I need to add one thing per “observed” item? For me it seems more useful, to have on “Pulse Thing” and configure the blocks with channel configuration? (As for inputs and outputs)

Well, let’s take a look into manual to LogoSoftComfort again: Logo can address 851 bytes (range 0 - 850). Each byte contains 8 bits. Means: we will have a thing with 6808 channels. It’s really huge thing:-)

@Euphi

• Why Inputs needs to be of type “Contact”. This seems wrong to me. It should be possible to configure them as Switch, too. This is especially true for NI, because an NI can be used as output from Openhab. So, usually I want to link a Switch item to it.

See here for explanation

@Euphi

• When you add a Digital Thing with PaperUI, only 20 Channels are created, but there are 64 available for NI, NQ or M? Is there a way to add theses channels in PaperUI?

Again, manual to LogoSoftComfort will help us. Siemens online documentation is helpful too. Just for info: Siemens has increased number of digital outputs to 20 (yeah, it’s really huge) in Logo!8 compared with 16 in Logo!7.

Kind regards,

Alexander
