Ethernet
Link Status A status string that represents the speed and
duplex setting being used to communicate with
the linking partner.
Frames Transmitted OK A counter that increments each time a frame is
successfully transmitted.
Collisions A counter that increments each time a frame is
retransmitted due to collision detection.
Excessive Collisions A counter that increments each time a frame is
not able to be sent due to reaching the
maximum collision status based on the
Truncated Binary Exponential Backoff
algorithm.
Frames Received OK A counter that increments each time a frame is
successfully received.
CRC Errors A counter that increments each time a frame is
received that has a checksum/CRC that does
not match what is calculated.
Alignment Errors A counter that increments each time a frame is
received that has a checksum/CRC error and
does not end on an 8-bit frame boundary.
Frames Too Long A counter that increments each time a frame is
received that is larger than the allowed
maximum size defined in the standards (frames
larger than 1518 bytes).
Frames Too Short A counter that increments each time a frame is
received that is smaller than the allowed
minimum size defined in the standards (frames
smaller than 64 bytes).
Modbus TCP/IP
Frames Sent A counter that increments each time a frame is
sent.
Frames Received A counter that increments each time a frame is
received.
Protocol Errors A counter that increments each time an
ill-formed message is received.
Active ConnectionscA status value that represents the number of
connections that are active at the moment the
diagnostics page is refreshed. A maximum of
32 connections are supported. Clicking Active
Connections opens a new window with a list of
all of the active client connections.
Accumulative ConnectionscA counter that increments each time a
connection is made to the ETG.
Maximum ConnectionscA status value that represents the maximum
number of connections that were active at any
given moment.
Inbound Read MessagescA counter that increments each time a read
request message is received.
Outbound Read MessagesdA counter that increments each time a read
request message is sent.
Inbound Write MessagescA counter that increments each time a write
request message is received.
Outbound Write MessagesdA counter that increments each time a write
request message is sent.
Inbound Reply MessagesdA counter that increments each time a reply
message is received.
Outbound Reply MessagescA counter that increments each time a reply
message is sent.
c Available when the serial port is in Master mode.
d Available when the serial port is in Slave mode
