XL4 Upgrade to Q04 Plus firmware

Need XL4 Plus functionality with Modbus or DF1 on all RTUs?

Upgrade all of your XL4 RTUs quickly and cost-effectively to extend the service life of the asset while your organisation works through a replacement strategy.

Why upgrade your XL4 RTU to with Q04 Plus firmware v7?

• Gives your XL4 the ability to capture over 65,000 data points instead of the original 255 it was shipped with, allowing you to capture as much data as you need from PLCs and other devices on your SCADA system (V7+).
• Supports multiple instances of Modbus RTU/ASCll/TCP and Allen Bradley DF1 industrial protocols on separate ports, slave RTUs can have individual poll rates (V7.05+)
• Supports Modbus over RS485, RS232, and Ethernet (V7.05+) .
• The Real Time Operating System (RTOS) ensures a more robust and faster performance of tasks.
• Base station communications can be made with digital radio, Ethernet, cellular, analogue radio and store & forward (RTU-RTU).
• New Dual Comms provides genuine redundant base station communications with simultaneous radio and Ethernet communications, thus retaining the security of radio communications in the event of failure of the LAN/WAN connection, particularly when you have large volumes of data to retrieve, e.g., in Drinking Water Standards applications.
• The Ethernet port can service multiple TCP connections simultaneously, so you can have Modbus and QComms running at the same time.
• Floating Point Arithmetic for more accurate 32 bit system integration (V7.16+).
• Easy USB firmware upgrades.
• Be ready to take advantage of future firmware enhancements that will include TCP connectivity to Workbench for remote RTU configuration, adding SDI12 and DNP3.

Two Upgrade options

Keen on XL4 Plus functionality but don’t need Modbus or DF1 on all RTUs?
The “XL4 Plus – Legacy” upgrade option is ideal. It includes QComms, Store and Forward (RTU-RTU) functionality but without the third-party communications options (as per the old XL4).

Need all the features?
Choose the XL4 Plus – Full – this fully bundled product incorporates the communications options ModBus and DF1 as well as QComms Store and Forward (RTU-RTU) that were previously add on options to an XL4.

The”XL4 Plus – Full” upgrade is a direct substitute for the XL4 in most installations. There are some exceptions where additional changes are required to take advantage of all the new features.
