EOL - Direct Link Profibus to Modbus Serial Gateway
Product phased out. Please call systerra for replacement options.

The BradCommunications™ Direct-Link™ gateway for PROFIBUS is built to enable the quick and cost effective connection of any Modbus device to a PROFIBUS-DP fieldbus. It is well suited for simple network extensions or the integration of legacy devices such as in the machine tool industry.

The BradCommunications Direct-Link gateway can act as a PROFIBUS-DP Slave on one side, and a MODBUS Master or Slave on the other side.

The gateway is built into the system without any lines of code. All parameters are set in a very user friendly way, via the usual PROFIBUS configuration tool. All the parameters are sent to the gateway automatically by the PROFIBUS Master at each network initialisation, permitting the replacement of the gateway without any configuration action.

Moreover, the Direct-Link gateway for PROFIBUS can drive up to 20 Modbus Slaves. It can exchange up to 244 bytes of inputs, and 244 bytes of outputs on PROFIBUS.

To complete the pre-defined Modbus commands, a “Pass Frame” mode is implemented to allow the composition of the Modbus commands directly from the PROFIBUS-DP buffer.

A standard Sub-DB9 Female connector provides the PROFIBUS interface and Plug Screw Terminal for Serial interface and Power Supply.
