Bit in status
WORD
Status → Underrange
Value below measuring range.
0x6000:01, 1 bit SW.0
Status → Overrange
Measuring range exceeded.
0x6000:02, 1 bit SW.1
Status → Extended
Range
Extended measuring range is used.
0x6000:03, 1 bit SW.2
Status → Data invalid
Input data are invalid.
0x6000:04, 1 bit SW.3
Status → Data invalid
No valid range selected.
0x6000:05, 1 bit SW.4
Status → Autorange
disabled
The Autorange function is disabled.
0x6000:06, 1 bit SW.5
Status → Error
The error bit is set if the value is invalid (wire
breakage, overrange, underrange)
0x6000:07, 1 bit SW.6
Status → Steady state
If the last four values are no more than x / 1024 of
end value apart, the "Steady state" bit is set to
TRUE
0x6000:09, 1 bit SW.8
Status → TxPDO State
Validity of the data of the associated TxPDO (0 =
valid, 1 = invalid).
0x6000:0F, 1 bit SW.14
Status → TxPDO Toggle The TxPDO toggle is toggled by the slave when
the data of the associated TxPDO is updated.
0x6000:10, 1 bit SW.15
Value
Current measured value as INT32, measuring
range end = 0x7F FF FF (standard)

SAI Inputs 0x1A02 (0x1A05)
This PDO contains the current measured value as REAL value. The format matches the REAL format from
the TwinCAT PLC Control.
The format matches the REAL format of IEC 61131-3, which in turn is based on the REAL format of IEC 559.
A REAL number (single precision) is defined as follows (See also
Beckhoff InfoSys: TwinCAT PLC Control:
standard data types
).
