BACnet Objects and Accessing Drive Parameters
Step

BACnet Node Addressing and
Related Drive Parameters
Step
4
BACnet Node Addressing
The BACnet node address is configurable by parameter F6-
45 in the drive. This defines the physical address of the drive
on the MS/TP network. In addition, both the Device Object
Instance Identifier (parameters F6-48 and F6-49) and the
Device Object Name are configurable. These allow the drive
to have a virtual address and simplify the controller
configuration.
After setting the addressing, a controller can initiate
communication to the drive. The drive will perform the
specified function and then send a response back to the
controller. The drive will usually respond immediately, but
may delay its response until it gets the token for commands
that may take extra local processing time.
Related Drive Parameters
The following parameters are used to set up the drive for
operation with the option. Parameter setting instructions can
be found in the drive Quick Start Guide or Technical Manual.
Confirm proper setting of the all parameters in the table
below, before starting network communications. After
changing parameter settings, cycle power to the drive for the
new settings to take effect.
<1>
To start and stop the drive with the option master device using
serial communications, set b1-02 to 3. To control the drive frequency
reference via the master device, set b1-01 to 3.
<2>
These parameters set the Instance Identifier of the BACnet
Device Object, where the F6-48 value is the least significant word
and the F6-49 value is the most significant word.
Example 1
: Set the Device Object Instance Identifier of "1234". 1234
decimal is equal to 4D2H (hexadecimal). Set F6-48 to 4D2H and
F6-49 to 0.
Example 2
: Set Device Object Instance Identifier to "1234567".
1234567 decimal is equal to 12D687H. Set
F6-48 to D687H and set F6-49 to 12H.

Present Value Access
The Present Value (PV) of BACnet objects can be read. In addition, some PVs can be written or commanded. A commandable PV is similar to writing the value, but the value is actually written into a priority array. The value occupying the highest priority in
the array will be used by the drive. The convention for showing how the PV is accessed is C = Commandable, Value written to a priority array. R = Readable, Value is read-only, W = Writable, Value written to the drive.

Reading Drive Parameters
Reading drive parameters not listed in the analog or digital objects is
accomplished using
AV29 and AV30 as shown below:
1.
In decimal, write the desired Modbus register to AV29.
2.
In decimal, read the value at the given register from AV30.
For example, to read the Frequency Reference Upper Limit, read
from parameter d2-01. Parameter d2-01 is located at Modbus register
0289H, which is decimal 649.
Set AV29 to “649”
Read AV30 to get the value.
Enter Command
Enter Commands are only required when using AV29 and AV30 to
write drive parameters. An Enter command is not required when
reading or writing to the other BACnet objects.
When writing parameters to the drive from a controller using BACnet
communications, an Enter command must be issued to enable these
parameters. This section describes the types and functions of the
Enter commands.
Accessing Drive Parameters
Writing Drive Parameters
Writing drive parameters not listed in the analog or digital objects is
accomplished using
AV29, AV30, and BV55 or BV56 as shown below:
1.
In decimal, write the desired Modbus register to AV29.
2.
In decimal, write the value to be written into AV30.
3.
At this point the value is pending. One of two actions must be taken to
complete the writing process:
Set BV55 to “ON” to move data to active memory.
Set BV56 to “ON” to move data into active memory and save to non-volatile memory.
For example, to reset the KWH Monitor, write a value of “1” to parameter o1-12.
Parameter o1-12 is located at Modbus register 0512H, which is decimal 1298.
Set AV29 to “1298”
Set AV30 to “1”
Set BV55 to “ON”
.
Enter Command Types
The drive supports two types of Enter commands as shown in the table below.
