Page 5: About The Manual
The BACnet MS/TP and SymbiNet communication protocol has been added. This manual provides the necessary information for the operation of the CFW-11 frequency inverter using the BACnet protocol. This manual must be used together with the CFW-11 user manual. -
Page 6: Introduction To The Serial Communication
The BACnet MS/TP network defines the BACnet message exchange using the RS485 interface as the physical layer. The characteristics of the RS485 serial interfaces available in the CFW-11 frequency inverter, as well as the BACnet protocol, will be presented next. -
Page 7: Bacnet Communication Accessory
2 BACNET COMMUNICATION ACCESSORY In order to make a BACnet interface available for the CFW-11 frequency inverter, it is necessary to use one of the RS485 communication kits described next. Information on the installation of these modules in the frequency inverter can be obtained in the guide that comes with the kit. -
Page 8: Indications And Switches
Enable the termination resistors only at two points, at the extremes of the main bus, even if there are derivations from the bus. ANYBUS-CC The RS485 interface can also be made available by using the passive Anybus-CC kit available for RS485. Refer to the Anybus-CC Communication Manual for information on this kit.

Page 9: Introduction To The Bacnet Communication
A BACnet equipment contains an information collection defined as objects and properties. A BACnet object represents physical or virtual information of the equipment, as a digital or analog input, control variables and parameters. The BACnet standard defines 25 types of objects. Each object is identified by a propriety called Object Identifier, which codifies the object instance type in a 32-bit binary number. -

BACnet MS/TP Message Structure The BACnet specification defines that the frame can have from 0 up to 501 bytes (octets), and that each byte is composed by 8 bits without parity, with start and stop bits, as showed in the Figure 3.2. - Page 11 BACnet Data not Expecting Reply (6) frame type: It is used by master nodes to convey the data parameter of a DL_UNITDATA.request that presents destination address, data, priority and message code. It does not wait for a response from the destination node.

Page 12: Address
The BACnet standard defines that the password is a string (set of ASCII characters) with up to 20 positions. The password used for the CFW-11 remote reinitialization is the same one used to allow the access for parameter content modifications, informed in the parameter P0000. This password can be a number between 0000 and 9999. -

Page 18: P0681 - Motor Speed In 13 Bits
111 Status and commands Description: It is the device BACnet interface control word. This parameter can only be changed via serial interface. For the other sources (HMI, etc.) it behaves like a read-only parameter. In order to have those commands executed, it is necessary to program the equipment to be controlled via serial. -
Page 19: P0683 - Serial Speed Reference
111 Status and commands Description: It allows programming the motor speed reference via the BACnet interface. This parameter can only be changed via serial interface. For the other sources (HMI, etc.) it behaves like a read-only parameter. In order that the reference written in this parameter be used, it is necessary that the drive be programmed to use the speed reference via serial. -
Page 20: P0696 - Value 1 For Analog Outputs
Using the network interface, write in P0696 the desired value for the analog output 1, between 0 and 100%, according to the parameter scale. BACnet objects of the ANALOG OUTPUT type mold the analog outputs, where: ANO0 - P0696. ... -
Page 21: P0760 - Bacnet Equipment Instance - High Part
It defines the low part of the BACnet equipment instance. The BACnet standard defines that the equipment instance must be unique in the network and it must present a value between 0 and 4194304. The BACnet instance will compose the Object Identifier property of the DEVICE object, which defines the equipment characteristics in the network. -
Page 22: P0762 - Maximum Master Number
Inverter Programming Manual: The BACnet instance is defined by using the parameters P0760 and P0761. The P0760 parameter content is multiplied by 10000 and added to the P0761 parameter content. Example 1: Instance = 542786 542786 / 10000 = 54.2786... -
Page 23: P0764 - I Am Transmission
∟ 113 Serial RS232 / 485 Description: The I AM telegram is used to identify the node in the BACnet network. When the option 1, periodically, is selected, then an I AM telegram is sent every 200 ms. NOTE! The equipment must be initialized when the content of the parameter P0764 is changed. -
