The article designation of Wachendorff Gateways is always to be seen from the perspective of the Gateways.

The article designation of the Gateways always consists of an order number and a product designation. The order number always starts with HD67..., followed by a three-digit number xxx, and possibly an extension of the order number after a "-". The product designation is given in plain text. For example: Gateway HD67044-B2-20, M-Bus Master / Modbus TCP Server.

This means that the Gateway HD67044 is M-Bus Master on the M-Bus side and Modbus TCP Server on the Modbus TCP side.

This means that you can connect M-Bus slaves to this Gateway on the M-Bus side and Modbus TCP clients to this Gateway on the Modbus TCP side. This principle can be used as an example for all Gateways.

Definition of master/slave & client/server

In the case of fieldbuses and/or serial communication between one or more devices, e.g. Modbus RTU (via RS232/485), the device identification is usually referred to as master and slave.
usually referred to as master and slave. RS232 is a point-to-point connection and can therefore only have one master and one slave. With an RS485, up to 32 participants are possible, here there can also only be one master but several slaves.
The master is active, the slaves are passive. The master initiates the communication, reads/writes data, the slave responds.

In all EtherNet-based communications (network), device identification is generally referred to as client and server.
The server is the passive part. It only responds to requests from clients. The client as the active part initiates the communication, reads/writes data, the server responds. The difference to serial communication is that a client in an EtherNet network can communicate with several servers virtually simultaneously because the communication is packet-based.

A1 is the narrow, tall housing for the control cabinet.

Previous dimensions (W x H x D): 23 mm x 107 mm x 120 mm
New dimensions (W x H x D): 22.5 mm x 90.7 mm x 123 mm

B2 is the flat, wide housing for the sub-distribution board.

Dimensions (W x H x D): 71 mm x 95 mm x 60 mm
Dimensions (W x H x D): 35 mm x 95 mm x 60 mm

The slim and space-saving A1 design is ideal for installation in the switch cabinet. The compact B2 design is ideal for mounting in the sub-distribution board.

The top-hat rail mounting and removable screw terminals ensure quick and safe installation and easy wiring of the devices!

There are also a few special designs, such as the DALI housing (identical to B2, but only 35 mm wide) and the industrial housing for applications that have to withstand extremely harsh environmental conditions.

Compositor SW67xxx is the configuration software for the HD67xxx hardware.

The Compositor is a configuration software (Windows) for the Gateways. The hardware is designated HD67xxx (xxx = three-digit number), the compositor is the respective configuration software for the corresponding hardware and is called SW67xxx (xxx = same three-digit number as the hardware).

The compositor can only be used for pure offline parameterization. There are no diagnostic or debug functions in the Compositor. The configuration cannot be downloaded from the devices (see Technical Note TN 2102, Copy / save / send Compositor configuration).
