Hello everyone,I have a question about reading out the digital inputs on the Cerbo-S GX via Modbus. According to the data sheet, this has 4 digital inputs. In the Modbus register overview there is only one register for the status (register 3422). Does this mean that the status of only one input can be queried or how do I get the status of all 4 inputs read?I hope that someone here can help me. Thanks in advance.
Not sure if you've worked this out yet, but I've had the same issue finding the GPIO registers.
In the spreadsheet it has 4 registers that refer to the inputs...
3420 - Count
3422 - State (this is not the state of the input digitally but the state of it's setup if you look at the options to the right in the spreadsheet)
3423 - Alarm (I think this is the register we need to read to see weather or not the input is active
3424 - Type (type of input related to door, pump, smoke etc

You have to use the different ID´s each with the 4 Registers:
