Description
Number of BTW requests that resulted in an incorrect BTW
identification code.
This value represents the total number of message frames
that have matched this slaves address on this port. This
count includes message frames which the slave may or may
not be able to parse and respond.
This value represents the number of good (non-error)
responses that the slave has sent to the master on this port.
The presumption is that if the slave is responding, the
message was good. Note: This is a frame count.
This value represents the total number of message frames
received by the slave, regardless of the slave address.
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.
This value counts the number of times the overrun error
occurs. This error occurs when the mainline Data Link Layer
routine cannot read the data received on the communication
port before it is overwritten.
This value counts the number of times an invalid length byte
is received. If the length of the message does not match the
length value in the message, this error occurs.
This value counts the number of times a bad CRC value is
received in a message.
This value counts the number of times the application layer
receives a message fragment buffer which is too small.
This value counts the number of times the sequence
numbers of multi-frame request fragments do not increment
correctly.
This value counts the number of times the source addresses
contained in a multi-frame request fragments do not match.
This value contains the total number of binary input events
which have occurred.
This value represents the number of binary input events
which are waiting to be sent to the master.
This value contains the total number of analog input events
which have occurred.
This value represents the number of analog input events
which are waiting to be sent to the master.
This value counts the number of times a bad function code
for a selected object/variation is received by the slave
device.
This value counts the number of times a request for an
unsupported object is received by the slave device.
