Unit Features
PROFIBUS-DP Gateway
Unit
The PROFIBUS-DP Gateway Unit is a standalone product, providing an inter-
face between a PROFIBUS-DP Master device and these units.
In addition to this functionality an auxiliary RS-232C interface is present on
the front of the Unit, to provide a direct connection to a Personal Computer.
This direct connection links the Personal Computer directly to Compoway-F,
thus by passing the PROFIBUS-DP connection.
Typical application setup
A typical application setup for the PROFIBUS-DP Gateway Unit is shown in
the figure below. The Gateway Unit interfaces between PROFIBUS-DP and
either Host Link or Compoway-F.
The Gateway Unit is present on the PROFIBUS-DP network as a slave unit.
The interface of the Gateway Unit is controlled by a Master unit on the net-
work. This Master unit can be any PROFIBUS-DP class 1 or class 2 master.
Compoway-F
Compoway-F is the OMRON proprietary serial communication bus system,
based on RS-485, to communicate with a range of Temperature Controllers,
including the E5ZN range of temperature controllers.
Host Link
Host Link is the OMRON proprietary serial communication bus system, based
on RS-422, to communicate with the R88A-MCW151-E for W-series drives.
