September 14, 2017 – Technologic Systems has announced that their single board computer, the TS-7680, will now support integration of Building Automation and Control networking protocol (BACnet). The TS-7680 embedded computer, powered by a 450 MHz ARM CPU, is designed to provide performance for applications which demand reliability and consistent connectivity. BACnet is a data communication protocol for Building Automation and Control Networks. Developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), BACnet is a national standard in more than 30 countries around the world, and an ISO global standard.
The TS-7680 was designed from the ground up to support many features common to BACnet networks, including RS-485, two 10/100 ethernet interfaces. The TS-7680 was built with industry in mind and comes equipped to handle power input allowing 8 to 40 VDC as well as 10 to 28 VAC, all housed in a plastic enclosure with optional DIN mount. It is designed to operate fanless in the industrial temperature range of -40 °C to +85 °C. The TS-7680 also offers a sub-watt low power operation mode as well as sleep mode.
The TS-7680 comes equipped with a Wireless 802.11b/g/n and Bluetooth 4.0+EDR module for out-of-the-box functionality and connectivity. For flexible data storage there is the option of 2 GB of SLC or 4 GB of MLC eMMC flash. The TS-7680 is built with functionality and flexibility in mind and offers variety of industry standard connectors including a USB host port, a microSD socket, two CAN ports, a high-precision battery-backed RTC, 30 V tolerant DIO, analog IO, and more. A 24-position industrial screw terminal connector provides a rugged, solid interface for four DAC and four ADC at 0 - 10 V to drive control functions. There is a 16 pin header with support for a cellular modem daughter card or a Power over Ethernet daughter card. Additionally, a 38 pin expansion header is available featuring adjustable GPIO using the FPGA's crossbar, 4 - 20 mA transmitters, and a transformer driver for an isolated power supply to support expansion boards with isolated interfaces including RS-485 and CAN ports.
The TS-7680 can boot from the onboard eMMC Flash or microSD card and comes preloaded with Linux kernel 3.14.28 and Debian Jessie along with the standard set of GNU development tools and familiar user space tools that come with the Debian distribution. The TS-7680 is the first Technologic Systems product to feature its TS-SILO technology powered by two onboard supercapacitors. With this option the embedded system has built-in protection from brownouts, spikes, and gaps and will provide 20 to 60 seconds of reserve power in the event of a power failure. This extra time gives the board time to power down and ensure file system integrity. There are no installation or maintenance requirements for this added functionality.
