TCP/IP Ethernet Network Statistics
A TCP/IP Ethernet module replies to local and remote statistics commands from the MBP_MSTR block with the the contents of the databuf array (see the information in the table below):

Board Status Word Bit Definition
NOTE: It is best to view the board status word in binary format.
The following table describes the bit definitions of the board status word:
Bit #
Definition
15
0 = Link LED off  1 = Link LED on
14
0 = Appl LED off  1 = Appl LED on
13
0 = twisted pair 1 = fiber
12
0 = 10 Mbit 1 = 100 Mbit
11 ... 8
(Reserved)
7 ... 4
Module type (see table, below)
3
(Reserved)
2
0 = half duplex 1 = full duplex
1
0 = not configured 1 = configured
0
0 = not running 1 = running
NOTE: Bits are numbered from right to left, starting with bit 0 (low bit). For example, PLC running = 0000 0000 0000 0001 and LED connection = 1000 0000 0000 0000.
The following table describes the word bit definitions for board status for the:
Bit #
Definition
15 ... 12
Module type (see table below)
11
(Reserved)
10
0 = half duplex 1 = full duplex
9
0 = not configured 1 = configured
8
0 = PLC not running 1 = PLC/NOE running
7
0 = Link LED off 1 = Link LED on
6
0 = Appl LED off 1 = Appl LED on
5
0 = twisted pair 1 = fiber
4
0 = 10 Mbit 1 = 100 Mbit
3 ... 0
(Reserved)
NOTE: Bits are counted from right to left, starting with bit 0 (low bit). For example, PLC running = 0x0100, Application LED = 0x0040, and LED Connection = 0x0080.
