ASI Controls System Architectures

ASI Controls provides a full range of system architecture options, ranging from single controller sites with automated dialout capability to large sites with thousands of networked controllers, multiple remote access points, and optionally OPC integration to other building automation systems.

ASI Controls provides interoperability options with the BACport BACnet/IP interface, as well as support for Modbus (ASIC/2's can serve as Modbus RTU Master for a network of Modbus RTU Slave devices) and OPC-DA. OPC is a data exchange standard that is commonly used in industrial process control settings. ASI WebLink is OPC-client software for custom front end development. Modbus RTU Master is a common standard for controlling slave devices such as VFDs, fans, pumps etc. Interoperability enables connectivity to and from many different devices and systems. ASI web front end software also support SSL/HTTPS, the Internet standard for secure browsing.

ASI Controls Supports Multiple Ethernet Networking Connectivity Options

The EtherLink/2 enables cost-effective communication with ASI controllers and control systems via an Ethernet TCP/IP local area or wide area network (LAN or WAN). Supported USB serial-to-Ethernet converters enable very low-cost Ethernet connectivity for a single ASIC/2-7540 configurable controller by leveraging the controller's built-in USB port. The ETH-8540 Ethernet Expansion Board is an optional extension board that plugs into the ASIC/2-8540 controller to provide cost-effective Ethernet connectivity for a single controller.
