*_AllDatXchgSta
BOOL
RO
All IO Devices
are in Data
Exchange
FALSE: Turned OFF by the Unit if it does not
receive data or receives invalid input data from
one or more IO Devices.
TRUE: Turned ON by the Unit if it is receiving
valid input data from all active IO Devices allo-
cated to the IO controller.
*_AllDevOutSta
BOOL
RO
All IO Devices
have con-
sumed output
data
FALSE: Turned OFF by the Unit if one ore more
IO Devices have not processed the set output
data.
TRUE: Turned ON by the Unit if all IO Devices
have processed the sent output data.
*_OneDevOutSta
BOOL
RO
At least one IO
Device has
consumed out-
put data
FALSE: Turned OFF by the Unit if none of the IO
Devices have processed the sent output data.
TRUE: Turned ON by the Unit if at least one of
the IO Devices has processed the sent output
data.
*_DevAlmSta
BOOL
RO
IO Device
Alarm
received
FALSE: Turned OFF by the Unit if no new IO
Device Alarms have been received. It will be
OFF if all alarms have been read or cleared.
TRUE: Turned ON by the Unit if one or more new
IO Device alarms have been received.
