Software Toolbox has released Top Server 5.5, the latest version of its OPC and native HMI device connectivity software application.

Powered by Kepware, Top Server 5.5 is claimed to feature enhancements to the main server and more than 20 drivers and plug-ins.

Top Server 5.5 extends the DNP WITS functionality with the implementation of Phase II support.

WITS Phase II adds support for writing to DNP object groups zero and 87 in keeping with the DNP WITS standard.

The latest release also includes an SNMP Agent plug-in, which enables Top Server to emulate an SNMP device on an Ethernet network.

The SNMP Agent plug-in supports SNMP Version 1 and 2C as well as the UDP protocol.

‘SNMP Agent enables Ethernet networks and their devices on the plant floor to be integrated with advanced IT monitoring systems that are utilising the SNMP protocol,’ said Colin Winchester, vice-president of operations at Software Toolbox.

The software’s new Pingitfirst utility ensures continuous connectivity to Ethernet-based devices and enhances the ability to troubleshoot connectivity issues.

Pingitfirst expands the capabilities of users to more effectively troubleshoot communications issues and more easily identify potential problem areas so they can be resolved in a timely fashion.

Top Server 5.5’s built-in modem functionality for serial drivers has been enhanced to support auto-dialling and improved phone-number management.

In addition, a multiple tag generation tool has been added to help users to quickly create large numbers of tags in the server database.

Additional improvements in Top Server 5.5 include: an OPC UA interface, including support for 2D arrays; an Advanced Tags plug-in, providing support for CSV import and export; a Bacnet IP driver, delivering support for device discovery on a Bacnet Network; and an SNMP driver, providing support for SNMP V3 including SNMP V3 Security.

Improvements have been made to the Allen-Bradley Controllogix Ethernet, DNP, Honeywell UDC Serial, Modbus Suite, Siemens Suite, SNMP, Ucon and Yokogawa drivers.

Top Server 5.5 will be available for download or as an upgrade during the week of 21 February 2011 for users with active support and maintenance contracts.
