BACnet Objects

Object MSI-3:  PID Mode
 

This object is for monitoring the general state of the drive’s PID mode as specified by Drive 
Parameter #70 (PID Mode).

State

1

OFF

PID disabled.

2

NORMAL

Enable direct-acting system (INC FDBK, DEC MTR SPD)

3

REVERSE

Enable reverse-acting system (INC FDBK, INC MTR SPD)

Object MSI-4:  H/O/A Mode
 

This object is for monitoring the drive H/O/A status. If the drive H/O/A is OFF (1) or HAND 
(2), serial speed/setpoint and serial start commands will not be accepted from the LAN. 
If the drive H/O/A is AUTO (3), depending on the setting of Drive Parameter #30 (Control), 
serial speed/setpoint and serial start commands will be accepted. For more information, 
refer to Section 3.4.

Object MSI-5:  Speed/Setpoint Reference
 

This object is for monitoring the source of the speed/setpoint reference. States 1 through 
9 are speed references. States 10 through 18 are setpoint references. This object must be 
in state 1, 9 or 10 for the LAN to be able to command the drive speed. This object must be 
in state 11 or 19 for the LAN to be able to command the drive setpoint. The state test table 
for this point is as follows:
