G1_Xist3 - Datalogic AMT58*-PN Series Instruction Manual

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.

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.

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.
