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.


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.

10.2. Gateway Included Components

Each gateway is supplied with the following:
 Anybus Communicator Profibus AB7000 OR Anybus Communicator DeviceNet AB7001.
 Male DB9-RJ45 Blue Subnetwork Connection Cable.
NOTE PROFIBUS / DeviceNet network cable and connector are not included.

 M ount the gateway on to the DIN-rail.
 T he DIN-rail mechanism works as follows:
1
o 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).
o 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.
 C onnect the Anybus Communicator to the PROFIBUS-DP / DeviceNet network.

 F or Profibus, set the PROFIBUS node ID (see section 10.7. 1 . Installation on page 32).
 C onnect the gateway to the serial subnetwork using the supplied Blue Male DB9-RJ45 Subnetwork
Connection Cable.

 F or a network with multiple drives, refer to 10.4.2. Multi Drive Network Example on page 29.
 G ateways supplied by Invertek drives are pre-configured to operate with 4 connected E3 drives,
unless an alternative number is specified when ordering.
 I f an alternative number of slaves are required, configuration files to suit between one and 4 slaves
1
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.
1
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.
