Update 4.11.1.4 | New categories for push notifications
Update 4.11.1 | New categories for push notifications
- New MQTT option in the process model for polling and controlling MQTT-compatible products
- Extended options for the JVP button
- Hiding Visu elements via data points
- General improvements to the Modbus editor
- The HTML calendar automatically switches the socket for the Christmas tree or pool pump on and off according to a defined schedule - without the need for a manual timer switch. → Increase convenience, reduce standby loads
- The shutters stay down on public holidays, even if they would otherwise go up early on working days. → Gain in comfort
- During a "home office" appointment, the office is heated; during a "company" appointment, the heating in the office remains off. → Energy savings, increased comfort
- During a trip, the control system simulates presence by randomly moving the blinds and switching the lighting. - A simple "holiday" appointment only prevents the shutters on the ground floor from being raised in the morning. → Energy savings, increased comfort
- The HTML calendar displays the collection dates for waste bins on a Smart Panel. → Added convenience
- Sockets and devices (e.g. televisions) are only switched on when a meeting room is actually booked. → Reduce standby consumption, energy efficiency
- The heating or air conditioning is only activated when the room is actually in use. → Energy efficiency
- The outdoor lighting is automatically switched according to a yearly schedule - public holidays and company closures are taken into account. → Energy efficiency
- Air conditioning is suspended on public holidays, even if a regular weekly programme is active. → Flexibility, energy efficiency
- The lighting is fully enabled on match days, but reduced to standard lighting during normal school operation. → Energy saving, increased comfort
- Devices in the kitchenette are automatically switched off after working hours, for example to prevent hobs from being accidentally left on. → Energy saving
- Ambient lighting is activated after closing time to create an attractive appearance. → Added convenience, energy efficiency
- Read values from Modbus devices (e.g. electricity meters, inverters, heat pumps)
- Write values to Modbus devices (e.g. change the operating mode of air conditioning systems)
- Integrate Modbus data points into the KNX installation and indicate them in the visualisation
If a participant communicates on the basis of Modbus RTU (via RS485), a Modbus RTU to TCP converter is required.
Solutions:
1. manufacturer-specific converter
- Some manufacturers offer their own RTU to TCP converters that are optimised for their devices.
- Baud rate → Communication speed (e.g. 9600, 19200, 38400 baud)
- Parity → None, even or odd
- Stop bits → 1 or 2
- Data format → e.g. 8N1 (8 data bits, no parity, 1 stop bit)
- Multiple devices on one Modbus RTU converter - If multiple Modbus RTU devices are connected to one converter, each device must have a unique Modbus ID and all Modbus RTU properties, such as baud rate or parity, must match
Where can I find these Modbus properties and registers?
In order to read or write the correct values from a Modbus device, precise information from the manufacturer is usually required.
The manufacturer usually provides a Modbus document (register list or data point list) containing the following information:
- Register ID → Which ID can be used to read or write which information
- Data type → What type the data is (e.g. integer, float)
- Access right → Whether the data point can only be read (Read) or also written (Write)
- Addressing → Whether the start digit of the register begins at 0 or 1
- Data sequence → Whether the data is transferred in big endian (from front to back) or little endian (from back to front) format
