Wireless PROFIBUS DP Communication Gateways

Product Description

The ProLinx High Speed Wireless PROFIBUS Solution creates a powerful wireless connection between Master and/or Slave devices on a PROFIBUS DP network. The modules are stand-alone 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 your 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 your PDP 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 overall PROFIBUS network node capacity can be calculated based on the available number of cyclic bytes available in the PDPS slave unit. The slave gateway becomes hard wired to an existing PROFIBUS network controlled by a third party master. The available number of PDPS slave cyclic data is 244 bytes Input and 244 bytes Output data (maximum 400 I/O bytes). For example, if each remote PROFIBUS third party slave connected to the PDPM master gateway consumed 6 Input/Output bytes each a total of 40 slaves can be configured. The remote wireless PDPM master allows up to 512 bytes input and 512 bytes output cyclic data. Multiple PDPS slave units could be used to accommodate larger PROFIBUS networks.

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.

Product Applications

Functional Specifications

Internal Database

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.

Application Data Area

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.

Status Data Area

This area is used to store error codes, counters, and port status information for each port.

Configuration Data Area

This 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 Specifications

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 serial communication interface (RS-485).

PDPMV1 Compatibility Notice to PDPM Users

The PDPMV1 product is not backward compatible with the PDPM product due to new enhancements and command structure. The PDPMV1 DPV1 master gateway product provides enhanced features to the PDPM DPV0 gateway product as follows:

1. Increased Cyclic IO. The DPPMV1 provides 768 Words of Input and 768 Words of Output.
2. ProSoft Configuration Builder (PCB) complete support. The PCB provides module level configuration and integrated PROFIBUS master network configuration support.
3. The PDPMV1 master supports DPV1 Class 1 or Class 2 DPV1 features such as: Acyclic communication with slaves for parameterization and other slave settings, Alarm handling, extended diagnostics.

PROFIBUS DP Slave Specifications

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.

Important Note: The slave node address is set to 126 by default in the module configuration file. The default node address must be changed to a valid address between 1-125 by the user for the slave to function on the PROFIBUS network.
