Profibus DP Slave to Veeder-Root Multiport Gateway

The FieldServer PROFIBUS DP Slave gateway makes it easy for integrators to interface devices utilizing various building or industrial protocols to PROFIBUS DP Slave networks. As the leading manufacturer of protocol gateways in the building automation industry, FieldServer has developed the largest driver library in the industry and the widest range of gateways available, designed to meet the needs of system integrators.

The FS-B3512-05 provides a wealth of features to enable data transfer between different devices and networks utilizing serial (RS-232 or RS-485), Ethernet, LonWorks and PROFIBUS DP Master. The multiport design allows for serial-to-serial, serial-to-Ethernet, LonWorks and PROFIBUS DP Slave interfaces. With a larger point count than any similar gateway, the FieldServer FS-B35 series provides a single device solution for your networking needs. The FieldServer is designed to meet a wide range of interface needs and it is easily configured as a master or a slave.

Configuration is easy, but if needed, configuration services are available from FieldServer support team. The proven FieldServer support team is recognized around the world for its knowledge of the many different protocols involved in building automation.

FieldServer continuously strives to enhance our gateways and the latest FS-B35 series includes a major software upgrade, resulting in significant enhancements in performance, including:

• 40% higher point count capability - some protocols are major memory hogs, and the result is that they can slow down performance of any gateway. With the greater memory enhancement, the FS-B35 Series can easily handle all of the drivers extremely well.
• Memory utilization monitoring - the user is provided with application memory statistics (in both kB and as a percentage of the available memory) enabling optimal matching of device models and configurations to specific applications.
• Improved stability and performance under high loads - the new software enhances the operation making it more forgiving to configuration problems with fewer crashes when capacity limits are reached.
• USB firmware update - this allows the firmware or configuration of the FieldServer to be updated from a USB flash drive whenever it is inserted, enabling users to easily update firmware in the field. This is a great time saver if you have multiple FieldServers in the field.

The Veeder-Root Serial Driver allows the FieldServer to transfer data to and from devices over either RS- 232 or RS-485 ports using Veeder-Root protocol as defined in Veeder- Root Document 576013-635 Revision J. The Veeder-Root Driver supports TLS350 as per Veeder-Root Document 576013-635 Revision Y, and TLS450 as per Veeder-Root Document 577013-950 Revision G. Since the data protocol is the same for the TLS-350+ as for TL-S350, it is assumed that the driver will support the TLS350+ but this has not been tested. The Driver also successfully communicates with the TLS-450 as it has the same data protocol. Please refer to the driver manual for hardware connections.

The FieldServer emulates a Client.

The Veeder-Root Serial Driver is a poll response driver. Only one query or command can be processed at a time.

A limited set of the queries and commands defined in the protocol specification have been implemented. The reason for the limitation is two-fold. Firstly, not all commands/queries will have any meaning to a Server device as they are principally defined to configure the Veeder-Root Device. Secondly, some commands return very complex data sets which cannot be processed in a method suitable for loading into the FieldServer’s Data Arrays.

The driver is capable of exposing its communications statistics which allows them to be monitored using a Server device. 

Supported Veeder-Root products

The Veeder-Root Gateway supports the following Veeder-Root Products:

• TLS-450 PLUS Automatic Tank Gauge
• TLS4i / TLS4c Automatic Tank Gauge
• TLS-350 Automatic Tank Gauge
• TLS-350 Plus Automatic Tank Gauge
• TLS-350R Automatic Tank Gauge
• TLS-300C/I Automatic Tank Gauges
• TLS-2/P Automatic Tank Gauge

The FieldServer Profibus DP Slave driver can be used to emulate a single slave station on a Profibus network. DP Masters can open a connection of up to 244 Bytes of Input and 244 Bytes of Output data, but not exceeding a combined total of 416 Bytes to the FieldServer. The FieldServer can be added to the Profibus network with the use of the supplied GSD file for the ANYBUS card. Connection to the Profibus network is via a DB9 port on the ANYBUS card.
