PC-Mxxx is a protocol conversion controller that complies with the BACnet B-AAC level dedicated programmable and independent operation.
It uses a 32-bit microprocessor, which can convert the commonly used MODBUS data to the BACnet data.
PC-Mxxx is often used to integrate equipment manufactured by different manufacturers in buildings. For example, constant temperature and humidity, air-conditioning unit, network-based fan coil unit, chiller unit, lighting control system, multi-function electric meter system, fire protection Alarm system, elevator control system and other facilities.
PC-Mxxx has two types: 1. Converting data for a control. 2. Converting data not for a control (PC-Mxxx-N). When the integration requirements are irrelevant control or data feedback applications that can allow a longer time, such as electricity meters and water meter data collection, you can choose the pure data converter model PC-Mxxx-N , To provide you with a more cost-effective choice.
【Feature】
- BACnet Advanced Application Controller (B-AAC) level device.
- Peer to peer read/write another BACnet device.
- 10/100M Ethernet port which can be set to be BACnet Ethernet, BACnet/IP, or MODBUS/TCP Server communication protocol. Convert BACnet AV/BV to and from MODBUS Register/Coil. Its MODBUS/TCP Server mode mapped BACnet AV or BV points to MODBUS Register or Coil for another MODBUS/TCP client to read or write.
- A MODBUS RTU/ASCII Master RS-485 ports for connecting to MODBUS RTU/ASCII Slave devices. LED indicator shows port communication status.
- Built-in MODBUS RTU RS-485 serial communication interface with indicator light and 2,500Vrms anti-interference potential isolation. Can be set as MODBUS RTU Master to connect various MODBUS RTU Slave devices; can also be set as MODBUS RTU Slave other MODBUS RTU Master devices to read.
- A RS-232 port to connect to computer by the AD-Linker setup cable. Set up the device by any hyper terminal software.
- Programmable, online edits mathematic operations such as add/subtract/multiply/divide and logic operations such as AND, OR in program for flexible data usage and control.
- 100/200/500/1000 AV or BV points for data exchange between different protocol sources.
- User can set a block data transfer, which saves communication time than one-by-one data transfer. Block size depends on the maximum size of MODBUS buffer available.
- Each analog point can be selectable do one time add/subtract/multiply/divide operation to adjust its value. This function eliminates the ratio or value adjustment operation in BACnet application level.
- Power failure backup function, data keep in FRAM.
