Hi,
i have difficulties adjusting the modbus. the device is a siemens climatix controller and when i check the modbus tcp with the modpoll i get the following values
Then you’d create a TCP Bridge Thing, and add your target IP address and so on to that.
Then you’d create a poll Bridge Thing, and configure a range of registers you would like to poll, by start address and by type.
If those mysterious [numbers] that you show are register addresses, you may need more than one poller. Modbus limits you to a hundred or so in one poll.
Then for any individual registers you are interested in, you create data Things described each address and howe you would like to interpret it.
You may create and link Items to your data Things, for use in your UI and your rules.
You can do this in PaperUI or by editing xxx.things files. Have a go, and we’ll help you with any snags.
What does your openhab.log tell you? Seems to enough there to poll, which may get revealed by twinkly lights on your equipment.
In your first post, you mentioned "FC4’ without explanation.
Modbus Function Code 4 is for "input’ type registers, so perhaps you meant to poll input not holding?
You won’t get any visible data unless you link Items to your channels. If you do have Items, what does your events.log tell you?
