![]() Wireless broadcasting of Modbus protocol could plausibly be intercepted by any third party within communication range, exposing a significant attack surface. Generally, this requires wired and physically secured communications media, but it is less appropriate where wireless communications are involved. Modbus can be considered a sound engineering decision when there is no requirement for compliance to network security standards and costs must be optimized. “This allows easy configuration and download of the Modbus device file into our controllers from the SGA software suite.” Modbus Use Case “Due to customer demand to integrate our reclosers into legacy communications and Scada systems that use Modbus protocol, we have implemented the Modbus protocol into our SGA software suite,” reports NOJA Power Group Managing Director Neil O’Sullivan. Serial implementations of Modbus carry additional limitations, such as the number of devices on a data link (maximum 247), and a lack of report by exception. Modbus provides no description of data objects. Modbus does not support large Binary objects There is no protection against unauthorized commands, or data interception The products do not require any third party add-ons.įind out more about Cyberlogic OPC Server Suites at provides no security features. All components of Cyberlogic OPC Server Suites are developed by Cyberlogic, and all required device drivers are integrated into the Suites. The built-in unsolicited messaging feature allows the configuration of an unlimited number of nodes that can initiate unsolicited data transmission, eliminating the need for polling for data. Cyberlogic’s OPC Servers include a Health Monitor that continuously verifies the operation of each network and data source, automatically switching to backups when there is a problem. ![]() Their built-in reliability features allow the configuration of an unlimited number of redundant networks and redundant data sources. Cyberlogic’s MBX OPC Server Suite supports all Modbus Plus adapters from Schneider Electric.Ĭyberlogic is the leading independent supplier of OPC Servers and industrial communication software with more than 100,000 copies shipped to 130 countries.Ĭyberlogic OPC Server Suites are integrated, all-in-one products. Since 1995, the Cyberlogic and Schneider Electric alliance produced a consistent and reliable connectivity architecture across all Windows platforms, making the MBX software the global standard for Modbus, Modbus Plus and Modbus/TCP communications. The full versions of MBX software suites are also available for trial download at the website. Users of previous versions of the MBX software can contact Cyberlogic for upgrade information. Users of Cyberlogic’s MBX family of software, which includes the MBX OPC Server Suite, MBX Bridge Suite and the MBX Driver Suite, can download a free update from Cyberlogic’s website at The update is available to any user with a version 6 installation. “And the TSXCUSBMBP can be used in place of any other PC-based Modbus Plus adapter from Schneider without any feature or performance loss,” he adds. “With this update, the new USB Modbus Plus adapter is fully compatible with all Windows software that uses the MBX Driver or the MBX OPC Server,” says Dan Muller, Director of Product Development at Cyberlogic. Schneider also announced in September that the TSXCUSBMBP is now shipping with the updated MBX Driver Suite software from Cyberlogic, based in Troy, Mich. Schneider Electric’s answer for a notebook-friendly Modbus Plus adapter is the new, USB-based TSXCUSBMBP. In addition to eliminating the legacy ports, the newer notebook computers no longer provide type-III PCMCIA slots. Shrinking size of notebook computers, and their growing use in industrial environments, created a demand for a new breed of network adapters.
