Sample Packets
The following are examples of requests to specific groups
of output registers.
Write to Output Reg201
Table 31 shows the result of a write request to output
OutOfService Reg201 (Function 5 Single Write, BO1 in
map).

Table 31. Sample packet for multiple write to output Reg220–Reg229.
Multiple Write Output Reg220–Reg229
Table 32 shows the result of a multiple write to BO
OutOfService Reg220–229 (Function 15 Multiple Write,
BO 20–29 in map).
Note that the Hi byte 0xCD addresses outputs 27–20, with
the least-significant bit addressing the lowest output 20
and the most-significant bit addressing the highest output
27. The Lo byte 03 addresses outputs 29–28, with the least-
significant bit addressing the lowest output 28. Unused
bits in the last data byte are padded with zeros

Table 32. Sample packet for write to output Reg201.
Binary Output (BO) Object – (Registers 2001 – 3260)
Each Binary Output object contains 12 properties that are
exposed to MODBUS. These object properties are
writable via Function Codes 6 & 16 and readable by
Function Code 3. Writes to the BO Value occur at
BACnet Priority Level 5 (Critical Equipment Control).
Table 33 shows list of registers associated with B01-B066.
