10. Fieldbus Gateways

10.1. Gateway Concept

The fieldbus gateway acts as an interface between the Modbus RTU interface and a high-level fieldbus network such as Profibus DP
or DeviceNet.
The gateway supports up to 8 drives connected as slaves.
NOTE When ordering the gateway, the number of slaves must be specified to ensure the correct configuration is loaded.
The gateway internally consists of two segments of memory. Data transferred from the fieldbus Master System is written to the first
memory area, and the fieldbus Master may Read data from the second memory area.

may be downloaded from the Invertek Drives website. The user may then load the desired slave
configuration to the gateway as follows:
o Connect the gateway to the PC via the configuration cable.
o Connect the power cable and apply power.
o Start the Anybus Configuration Manager program on the PC.
(The Anybus Configuration Manager software attempts to detect the serial port automatically.
If not successful, select the correct port manually in the "Port"-menu).
o Configure the gateway using the Anybus Configuration Manager and download the relevant
configuration to suit the number of connected slave drives.
o Set up the PROFIBUS communication in accordance with the configuration.
