Details
Depends on whether or not a local or a remote I/O station
has detected any link parameter error in the master station
Depends on the results of initial communication between a
local or remote I/O station and the master station.
(Parameter communication, etc.)
Depends on the error condition of a local or remote I/O
station.
Depends on the error condition of the forward and reverse
loop lines of a local or a remote I/O station.
Depends on whether the local station is online or offline, or is
in station-to-station test or self-loopback test mode.
Depends on the error condition of the forward loop line.
Depends on the error condition of the reverse loop line.
Depends on whether or not loopback is occurring at the local
station.
Depends on whether or not data has been received from the
master station.
Depends on whether or not a tier three station has received
data from its master station in a three-tier system.
Depends on whether or not link parameters have been
received from the master station.
Depands on the data link condition at the local station.
Depends on whether or not the local station is executing a
forward or a reverse loop test.
Control is performed depending on whether the master
station is in the STOP or PAUSE mode.
Control is performed depending on whether a local station
other than the host is in the STOP or PAUSE mode.
Depends on whether or not a local station other than the host
is in error.
