PF-BM12

Integration Layer Device

BACnet Ethernet Protocol Converter (Bacnet IP - Modbus TCT - DFC**)

PF-BM12 is a network controller/gateway device for the DFC series controllers allowing communications to the DFC Series controllers via Bacnet IP or MODBUS / TCP standards.

Description

PF-BM12 is a network controller/gateway device for the DFC series controllers allowing communications to the DFC Series controllers via Bacnet IP or  MODBUS / TCP standards. It can perform group or individual control on the network such as start/stop, temperature control, Fan Mode, scheduled on / off, overrides etc and also monitor temperature, system operation, fan speed operation, alarms etc.

It is a programmable controller therefore standard Bacsoft DDC control programming can be achieved for billing and other functions. As a Bacnet BTL listed device it conforms with American National Standards (ANSI), Association of American Air Conditioning (ASHRAE), European standards, therefore making it compatible with any other BACnet or Modbus TCP system. There is one Modbus RTU port that allows connection up to 32 x DFC** devices.

Features

  • Complies with BACnet B-AAC standard protocol.
  • Complies with MODBUS/TCP standard protocol..
  • Equipped with one ETHERNET port for either BACnet ETHERNET or BACnet/IP or MODBUS / TCP Server protocol.
  • Equipped with two FCnet RS-485 communication ports and a communications indicator showing the status of sending and receiving signal of ports, PF-BM12 links up to 32 various devices per Lan such as the DFC…etc.
  • Uses a RS-232 communication interface through AD-Linker cable to modify PF-BM12 parameters via HyperTerminal program from a workstation.
  • PF-BM12 automatically synchronizes controller clocks that connected to its FCnet network with central monitoring system time.
  • PF-BM12 converts DFC micro control fan points into standard BACnet objects allowing other Bacnet devises to monitor & control. (Note: Every DFC has up to 60 (AI*10 /AO*10 /AV*10 /BI*10 /BO*10 /BV*10).
  • PF-BM12 supports DDC functions such as online-editing, control logic program download, real-time debugging, control of enthalpy, dew point temperature and PID control that the HVAC common functions as well as logarithmic, trigonometric functions, roots and other advanced math function.
  • PF-BM12 has clock, 2 calendar (Calendar), 20 timetable (Schedule), 4 notice categories (Notification Class), 40 alarms event log (Event enrollment) of the BACnet standard objects. Schedule and alarm event logging support external object access.
  • Supporting Non-volatile Memory with capacity of 200 BACnet analog value (AV) and 10 binary outputs (BO) object program memory, PF-BM12 automatically store parameters into FRAM to be used as energy management, billing and other operational purposes when power is off. BO0 ~ 9 of 10 BO-point support Priority function.
