BACnet MS/TP to Modbus RTU Converter
AT-DSCB BACnet MS/TP to Modbus Converter with Logical and Arithmetic Control
AT-DSCB is a standalone BACnet MS/TP B-ASC class programmable controller with Modbus Master or Slave port. It uses 32-bit microprocessor core, communication up to 76,800 bps, transmission distance up to 1,200 meter. Modbus RTU port max 38400 bps, can be master or slave and read or write to up to 100 registers. AT-DSCB BACnet gateway conforms international BACnet MS/TP communication protocol and fully compatible with any BACnet system.
Conforms to ASHRAE and ISO16484-1 defined BACnet ASC standard communication protocol, compatible with BACnet system.
An MS/TP(Master-Slave/Token-Passing) communication interface connect to upper layer global controller.
An MSnet communication interface connects to a MODBUS RTU device.
Carry out calculations such as proportional, integral, differential, floating, logic, arithmetic and etc.
100 Binary Value(BV) and Analog Value(AV) points.
The analog value adopts high precision floating-point calculation.
Provide power failure backup function for all AI/BO/AO/BV/AV values keep in FRAM for at least 10 years.
