Bristol Babcock upgrades CPUs for controllers


Bristol Babcock Inc. has released the CW_10 and CW_30 CPU upgrades for the installed base of RTU 3310 and DPC 3330 controllers.

The new CPU products are offered as an upgrade path to the ControlWave architecture for existing 3310 and 3330 systems, allowing existing customers to maintain their investment in I/O points, wiring, communication infrastructure, and application program development. The CW_10 and CW_30 CPUs are direct replacements for the 3310 and 3330 CPUs. Customers can remove existing CPU and communication cards and replace them with the new ControlWave architecture cards. The CW_10 and CW_30 CPUs support all commonly used analog, discrete, and counter I/O-cards, as well as modems and radios currently installed in the RTUs. Communication compatibility is maintained through the same use of BSAP and Modbus protocols as in the 3310 and 3330.

ControlWave architecture features include compatibility with industry standards such as IEC 61131-3 programming, Ethernet, IP and FTP communication, support for 56-bit encrypted user name/password security sign-on, and multiple user access levels. It also offers faster execution speed, lower power consumption, and a larger and more flexible memory model.
