Offset Variable Name Description
40 206 6 DNP Master Port Device
Memory Block Count
This value represents the number of
memory allocation blocks for slave
devices. This number should be one
greater than the number of slave
devices. The extra device is held for
the broadcast device.
41 206 7 DNP Master Port Frame
Block Count
This value represents the number of
physical layer frame memory allocation
blocks used by the program.
42 207 2 DNP Master Port Data
Link Receive Block
Count
This value represents the number of
receive data link layer memory blocks
allocated.
43 207 3 DNP Master Port Data
Link Transmit Block
Count
This value represents the number of
transmit data link layer memory blocks
allocated.
44 207 4 DNP Master Port
Application Layer
Receive Block Count
This value represents the number of
application layer receive memory
blocks allocated.
45 207 5 DNP Master Port
Application Layer
Receive Block Count
This value represents the number of
application layer transmit memory
blocks allocated.
46 207 6 DNP Master Port Device
Memory Allocation Error
Count
This value represents the number of
memory allocation errors for device
blocks.
47 207 7 DNP Master Port

Memory Allocation Error
Count
This value represents the number of
memory allocation errors for data link
layer transmit blocks.
50 208 4 DNP Master Port
Application Layer
Receive Memory
Allocation Error Count
This value represents the number of
memory allocation errors for application
layer receive blocks.
51 208 5 DNP Master Port
Application Layer
Transmit Memory

This value represents the number of
memory allocation errors for application
layer transmit blocks.
52 208 6 DNP Master
Synchronization Error
Count (Physical Layer
Error)
This value counts the number of times
a sync error occurs. The error occurs
when extra bytes are received before
the start bytes (0x05 and 0x64) are
received.
