4-4-3 Number of Message Resend Overflows (FL-net Unit to CPU Unit)
The number of times ($0 to $FFFFFFFF) a message is resent three times or
more during message transmission is stored. This error may occur due to the
network configuration or line load.
4-4-4 Number of Message Transmission Receive Errors (FL-net Unit to
CPU Unit)
The number of occurrences ($0 to $FFFFFFFF) of sequence errors, illegal
source node numbers, illegal transaction codes, and illegal sequence ver-
sions during message reception is stored.
4-4-5 Number of ACK Errors (FL-net Unit to CPU Unit)
The number of occurrences ($0 to $FFFFFFFF) of ACK errors during mes-
sage reception is stored. This error may occur due to the network configura-
tion or line load.
4-4-6 Number of Self Removals (FL-net Unit to CPU Unit)
The number of times ($0 to $FFFFFFFF) a node removes itself from the net-
work during communications is stored. Self removal occurs when a token
holding timeout occurs at least four times This error may occur due to the net-
work configuration, line load, or line settings.
4-4-7 Number of Removals Due to Skips (FL-net Unit to CPU Unit)
The number of times ($0 to $FFFFFFFF) a node is removed due to a local
node skip during communications is stored.
4-4-8 Total Number of Send Errors (FL-net Unit to CPU Unit)
The number of collisions ($0 to $FFFFFFFF) from 16 or more that occurred
during packet transmission is stored. This error may occur during normal
operation due to the network configuration or line load.
