System data: Sensor data
Sensor data can be read into the control via the following system data:
Meaning
Sensor configuration
Clamped state
1)
Measured value ana‐
log sensor S1
1) 2)
Status digital sensors
<Axis>: Machine axis name: AX1 ... AXn or spindle name: S1 ... Sm
See Section "Clamping status (Page 840)"
1)
Sensor S1: 0 - 10 V
2)
Analog actual value: 10000 increments, resolution 1 mV
Example:
SIMATIC S7 input module: 27648 increments, resolution 0.36 mV
Adaptation factor if you change to a spindle with SMI 24: (10000 incr. * 1 mV) / (27648 incr.
* 0.36 mV) = 1.00469393
