To configure the gateway component, you have to perform the appropriate settings with the configuration software of your PROFIBUS Master (class 1).
The PROFIBUS gateway component is created as a so-called “modular DP-V0 Slave”. This means that the process data exchanged between the gateways can be structured application-specific on the profibus side.
The gateway component is equipped for this with virtual slots (installation positions). PROFIBUS controllers use these slots to address selected process data. Each slot can contain one module. Within these modules is the process data to be exchanged. Hence, you have the possibility of aggregating associated process data in one slot. This means, for example, that you can poll a compact process mapping of associated states.
If you do not want to use a slot, you can mark it with an empty module. You do not have to perform any further settings on the empty module.
The process data is accessed between the gateway components in separate memory areas for input and output data. The sequence order in which the access takes place depends on the configuration of the modules.
The data of the modules is stored directly in succession in the memory area for the data exchange between gateways (see example further below).
Info! The gateway component does not support any extended diagnosis data.
Byte order:
The bytes are transferred to the controller in Big Endian Format.
Module Configuration
A maximum of 64 slots, each with 244 bytes for input and output data, is available for the module configuration. The modules are preset in the GSD and cannot be changed.
The following modules are available for loading the Slots:
| Module number | Module type | Size[Bytes/Words] | Access |
| 0 | Empty module | 0 | – |
| 1 | Output | 1 | Byte |
| 2 | Output | 2 | Byte |
| 3 | Output | 4 | Byte |
| 4 | Output | 8 | Byte |
| 5 | Output | 16 | Byte |
| 6 | Input | 1 | Byte |
| 7 | Input | 2 | Byte |
| 8 | Input | 4 | Byte |
| 9 | Input | 8 | Byte |
| 10 | Input | 16 | Byte |
| 11 | Input/Output | 1 | Byte |
| 12 | Input/Output | 2 | Byte |
| 13 | Input/Output | 4 | Byte |

Example of Module Configuration
The following slots are to be configured:
| Slot | Module type | Size [Bytes/Words] | Access | Module number |
| 1 | Input | 1 | Byte | 6 |
| 2 | Input | 16 | Byte | 10 |
| 3 | Output | 16 | Byte | 5 |
| 4 | Empty module | 0 | – | 0 |
| 5 | Input | 1 | Byte | 6 |
| 6 | Output | 8 | Byte | 4 |
| 7 | Input | 4 | Byte | 8 |
| 8 | Input/Output | 4 | Byte | 13 |
| 9 | Empty module | 0 | – | 0 |
| 10 | Input/Output | 1 | Word | 26 |
| 11 | Output | 1 | Word | 16 |
| 12 | Input | 1 | Word | 21 |
The following tables provide the memory maps of the example and are thus used for data exchange with other gateways.
