Fieldbus Gateways
5.1
Gateway Concept
The fieldbus gateway acts as an interface between the Modbus RTU interface embedded into the Optidrive E3, and a high level fieldbus
network such as Profibus DP or DeviceNet. The gateway supports multiple drive connection up to 8 drives, providing a cost effective method to
connect Optidrive E3 units to a Profibus network.
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.

Data
The fieldbus Master can normally be configured to Read and Write the entire gateway memory area in a single transaction, or separate
transaction per drive may be configured. The gateway is the pre-configured by Invertek to carry out the necessary individual Modbus RTU
transactions to communicate with the Sub Network of connected drives.
5.2
Gateway Included Components
Each gateway is supplied with the following:-
Anybus Communicator Profibus AB7000 OR Anybus Communicator DeviceNet AB7001
Anybus Communicator Resource CD (Includes configuration software, manuals, GSD / EDS file and application notes)
Female DB9-RJ10 Black RS232 configuration cable
Male DB9-RJ45 Blue Subnetwork Connection Cable
Note: PROFIBUS / DeviceNet network cable and connector are not included.
5.3
Gateway Installation
Mount the gateway on to the DIN-rail
The DIN-rail mechanism works as follows:
To snap the gateway on, first press it downwards (1) to compress the spring in the DIN-rail mechanism, then
push it against the DIN-rail as to
make it snap on (2)
To snap the gateway off, push it downwards (1) and pull it out from the DIN-rail (2), as to make it snap off
from the DIN-rail
Connect the Anybus Communicator to the PROFIBUS-DP / DeviceNet network
For Profibus, set the PROFIBUS node ID (see “Module Front” on page 42)
Connect the gateway to the serial subnetwork using the supplied Blue Male DB9-RJ45 Subnetwork
Connection Cable
For a network with multiple drives, refer to „Multi Drive Network Example“ on page 38
Gateways supplied by Invertek drives are pre-configured to operate with 4 connected E3 drives, unless an
alternative number is specified when ordering.
If an alternative number of slaves are required, configuration files to suit between one and 4 slaves may be
downloaded from the Invertek Drives website. The user may then load the desired slave configuration to
the gateway as follows :-
Connect the gateway to the PC via the configuration cable
Connect the power cable and apply power
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)
Configure the gateway using the Anybus Configuration Manager and download the relevant configuration
to suit the number of connected slave drives.
Set up the PROFIBUS communication in accordance with the configuration
