Product Name(s): Computrols Building Automation System (CBAS)
Product Description: CBAS is building automation system software. Menus are mouse-driven with on-line help screens. CBAS software refers to field points by their full name and does not use point assignments or abbreviated characters. CBAS allows users to display point statuses in a variety of ways including summaries, logical groups, and custom graphics. CBAS software can be programmed by using English language “If/Then” logic statements.
Product Application(s): CBAS can control the following: - HVAC - Fire - Access CBAS software can integrate with various other manufacturers’ field controllers by interface channels which use RS485 protocols such as Bacnet, ModBus RTU, Opto, and N2.
