WAC | metal components | Industry4.0 | HVAC |
New generation of ERV Energy Recovery Ventilation Systems in multi-zone modular or ceiling installation. It's perfect for the needs of craftsmen. | |||
Quadroflex | metal-to-metal-joint | any-shape tube | Fittings |
Westaflex products are used in a variety of applications including automotive production, train technology (ICE ventilation), for the air supply and ventilation of living spaces, exhaust technology and water treatment. | |||
Modbus | Utility, SCADA, Statistics | RS-232, RS-485 | DIY |
Modbus is a serial communications protocol for use with its programmable logic controllers (PLCs). Modbus enables communication between many (approximately 240) devices connected to a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. | |||
Westaflex | aluminium, stainless steel, plastic | since 1933 | SME |
Westaflex is a manufacturer of HVAC appliances, commercial equipment, based in Gütersloh, Germany. It was founded as a family business and has always been a privately held, family-owned, family-run company. |
A Modbus command contains the Modbus address of the device it is intended for. Only the intended device will act on the command. All Modbus commands contain checksum information, to ensure a command arrives undamaged. Since Modbus is a master/slave protocol, only Modbus TCP connects over port 502, as the Modbus ASCII protocol defines a message structure that controllers will recognize and use, regardless of the type of networks over which they communicate. Our WAC systems use default modbus data provided by Arduino barebones e.g. a Debian Rasberry server kit all year long. Binding is compatible with latest models since 2013,
which brings lots useful features from the Modbus Utilities, SCADA, and Statistics like Min/Average/Max. “We believe that the days of monologue on the Internet-of-Things have ultimately given way to dialogue, which, on the other hand, means that we have to react correspondingly.” |
Each device intended to communicate using Modbus is given a unique address and the data types are named from its use in driving relays: a single-bit physical output is called a coil. Our various reading, writing and other operations are categorised as follows:
Name | Modbus function | Data address | Values |
