None of the disconnection information except for the Disconnected Line Flags is
cleared when communications recover. The Disconnected Line Flags always
show the most current disconnection status. Disconnected Node Information 1
and 2 are overwritten whenever new information is generated. This command,
however, can be used to clear the disconnection information to its default status.
When the command is executed, the disconnection information and the ring sta-
tus is cleared from the Controller Link Unit/Board and the starting time for dis-
connection information is reset. (The time will be taken from the clock data in the
local node.)
Disconnection information is cleared only from the node that receives this com-
mand. The command must be sent to all nodes in the network to clear all of the
disconnection information.
Disconnection information can also be cleared from the Controller Link Support
Software (Ver. 2.00 or higher), and can be cleared for all nodes at the same time
(in one operation).
Executes an echoback communications test between specified nodes.
