FINS Commands for SYSMAC LINK Units
Section 6-4
Cyclic non-fatal errors (response):
These eight bytes indicate nodes in
which non-fatal errors occurred in cyclic transmission. When a bit in the fol-
lowing matrix is ON, a non-fatal error occurred in the corresponding node.
Bit 0 of the first byte and bit 7 of the eighth byte are always OFF.
Cyclic error counters (response):
One of these 62 bytes is allocated to
each node to indicate how many cyclic errors occurred since startup. The first
byte is allocated to node address 1, the second to node address 2, etc. Each
number is 2-digit hexadecimal, so 00 to FF (0 to 255 decimal) errors can be
recorded for each node. If more than 255 errors occur, the number will remain
at 255.
