ProSoft Technology, a leader in the field of industrial communications, is offering its new ProLinx High Speed Wireless Profibus Solution. The units overcome the problem of high-speed data transfer of Profibus DP over wireless. This system will now allow users of this Fieldbus type to maintain their network data rates throughout their entire system. The Profibus data rates range from 9,6 kilobit/s to 12 megabit/s and all the intermediate standard rates are available.
This system offers a powerful wireless connection between Master and/or Slave devices on a Profibus DP network. The modules are standalone DIN rail-mounted wireless protocol gateways providing an efficient and powerful, over-the-air wireless protocol and a wired Profibus Master or Slave interface port.
On the field device side, the Profibus DP Master Protocol driver is configured as a Class 1 Profibus DP Master to interface with and control Profibus DP Slave devices. It provides access to both standard and extended diagnostic information and provides freeze/sync capability. Configuration of the Profibus network is accomplished using the ProLinx SyCon Configuration software.
On the controller side, the Profibus DP driver is configured to interface with a DP master. It provides 200 bytes of read and 200 bytes write cyclic data. The module also provides common and extended diagnostic information and other important module status information.
The Profibus DP Master (PDPM) protocol driver supports Master implementations of the protocol on either a Mono-Master or Multi-Master network. The Profibus DP Slave (PDPS) protocol interface supports the Profibus V0 Slave implementation protocol, providing powerful data transfer capability between the ProLinx module and Siemens PLCs or other hosts. User configurable data mapping and DP port operation make the interface an easy to use and powerful data transfer tool.
Users will be able to connect various field devices using different networks or protocols and share data between these devices 'over-the-air'. This is accomplished by exchanging shared common database information wirelessly with ProSoft Technology's efficient but powerful wireless protocol, PWP. ProLinx is the first product line to benefit from this technology.
The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information. The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database. The status data area is used to store error codes, counters, and port status information for each port.
The configuration data area contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, this area.
Profibus DP Master Protocol
The Profibus Master Protocol driver exists as a single port implementation. The driver can be configured as a Class 1 Profibus Master to interface with other Profibus slave devices. The unit is also used for configuration of the nodes on the Profibus network. It provides access to both standard as well as extended diagnostic information. The Profibus master port can be used to continuously interface with Profibus slave devices over a RS485 communication interface.
Profibus DP Slave
The Profibus DP Slave driver gives access to the ProLinx unit's internal database via 200 bytes of Input data and 200 bytes of Output data. These Input and Output data blocks are mapped by the user within the ProLinx module's data memory allowing the user maximum flexibility and data transfer with other protocols. A GSD File (DP slave signature file) is available from the ProLinx website.
