PROFINET IO data description

4.11 Status word (G1_ZSW)
The status word defines encoder states, acknowledgements, er-
ror messages of major encoder functions.
Bit Function
0..7 Function status: Reference mark search, measure-
ment on the fly
8 Probe 1 deflected
9 Probe 2 deflected position mode (Preset)
10 Reserved, set to zero
11 Requirements of error acknowledgment detected
12 Set/shift of home position (Preset) executed
13 Transmit absolute value cyclically
14 Parking sensor active
15 Sensor error
Table 22 Status word (G1_ZSW)
Note: If bit 13 Transmit absolute value cyclically or bit 15 Sen-
sor error is not set there is no valid value or error code
transferred in G1_XIST2.
Note: Bit 13 Transmit absolute value cyclically cannot be set
at the same time as bit 15 Sensor error as these bits
are used to indicate either a valid position value
transmission (bit 13) or the error code transmission
(bit 15) in G1_XIST2.
