Description
Min Sec Day Hour Year
Time of connection configuration Number
First node to read (command): Specify the node to start the configuration
from counting downstream direction (SL2) from the local node. The number is
specified as a 2-digit hexadecimal value between 00 and 3E (decimal 0 to 62).
Number of nodes to read (command and response): In the command,
specify the number of node addresses to return as a 2-digit hexadecimal
value between 00 and 3E (decimal 0 to 62). If 00 is specified, the node
addresses of all nodes downstream from the current node will be returned.
The response will return the number of node addresses actually read as a 2-
digit hexadecimal value between 00 and 3E (decimal 0 to 62).
For this command, the node address of the local node is always returned first
regardless of the setting for the first node to read. The number of other nodes
for which addresses are returned will thus be one less than the specified num-
ber of addresses. The node address of the specified first node will be returned
as the second node address.
Time of connection configuration (response): These parameters show the
seconds, minutes, hour (0 to 23), date, month, and year (the rightmost two
digits) in BCD specifying the time that the connection configuration was last
updated. The information is updated each communications cycle in Token
Bus Mode as long as the ling connection status is normal. The time will be
taken from the clock data in the local node.
Node address (response): Node addresses are returned in order as 1-byte
hexadecimal values starting from the node address of the local node and then
the node address of the node specified as the first node to read.
If the number of nodes to read and the specified first node to read are such
that the local node is included in the reading range, node addresses will be
read only through the node next to and upstream from the local node. The
read will end normally.
Example: In the following example, the first node to read is specified as 5 and
the number of nodes to read is specified as 6.
