SAI Inputs 0x1A00 (0x1A03)
This PDO contains the status data and the resistance of the terminal. The resistance value is issued as a 32-
bit value. The terminal status is shown as WORD.

SAI Inputs 0x1A01 (0x1A04)
This PDO contains information on the selected measuring mode and the current range. The two values are
also available within a settings WORD.
Name Explanation
Mode Current measuring mode:
0: 4-wire measurement
1: 4-wire measurement, single-shot mode
2: 2-wire measurement
3: 2-wire measurement, single-shot mode
Range Current measuring range
(lower value is decisive for autorange operation):
-1: 10 mΩ - 100 mΩ
0: 100 mΩ - 1 Ω
1: 1 Ω - 10 Ω
2: 10 Ω - 100 Ω
3: 100 Ω - 1 kΩ
4: 1 kΩ - 10 kΩ
5: 10 kΩ - 100 kΩ
6: 100 kΩ - 1 MΩ
7: 1 MΩ - 10 MΩ

Explanation
Value below measuring range.
Note: since each measuring range also measures
up to 0 Ohm and there are no negative resistance
values, this bit is never set.
Measuring range exceeded.
Extended measuring range is used.
Input data are invalid.
No valid range selected.
The Autorange function is disabled.
The error bit is set if the value is invalid (wire
breakage, overrange, underrange)
If the last four values are no more than x / 1024 of
end value apart, the "Steady state" bit is set to
TRUE
Validity of the data of the associated TxPDO (0 =
valid, 1 = invalid).
the data of the associated TxPDO is updated.
Current measured value as INT32, measuring
range end = 0x7F FF FF (standard)
