3. Serial Communications
F. Communications
1. The VFD shall have an RS-485 and Ethernet as standard. The standard
embedded protocols shall be BACnet MS/TP, BACnet IP, Modbus RTU,
Modbus TCP, Johnson Controls N2 and Siemens Industry Inc, Building
Technologies Division P1 (FLN) protocol, Johnson Controls Inc. N2 Metasys
protocol. There shall be an optional LON (LONMARK) interface.
2. Serial communication capabilities shall include, but not be limited to, run-stop
control; speed set adjustment, proportional/integral/derivative PID control (Set
Point) adjustments and accel/decel time adjustments. The drive shall have the
capability of allowing the DDC to monitor feedback such as process variable
feedback, output speed/frequency, current (in amps), % torque, power (kW),
relay outputs, digital inputs and diagnostic warning and fault information.
Additionally, remote (LAN) VFD fault reset shall be possible. A minimum of 15
field parameters shall be capable of being monitored.
