G1_XIST3
[Unsigned, 64 bits]
It is defined as Sensor 1 position actual value 3. This 64-bit position
value is intended to support the encoders having a measuring length
which exceeds 32 bits
G1_XIST3 has the following format:

binary format;

the actual position value is always right aligned, a shifting
factor is not used;

the settings in the encoder parameter data affect the position
value in G1_XIST3 if Application Class 4 is enabled.
IO data 1 2 3 4
Format 64-bit position value
STW2_ENC
[Unsigned, 16 bits]
It is defined as Encoder control word 2. Control word
STW2_ENC
includes the Control by PLC mechanisms from PROFIdrive STW1
and the Controller Sign-Of-Life mechanism from PROFIdrive
STW2. mechanism from PROFIdrive STW2.

Controller Sign-Of.Life
Control by PLC
Bit 10
If the
Compatibility mode is enabled (see on page 90), then bit 10
Control by PLC is ignored. In this case control word G1_STW and
setpoint are always checked.
If the
Compatibility mode is disabled (see on page 90), then bit 10
Control by PLC is checked. So control word G1_STW and setpoint
are checked only if the bit Control by PLC is set.
