Example accesses with IOL_CALL
In this example, the variable table "HMI" serves to visualize the procedure of the read and
write access via IOL_CALL. The sensors’ process data are shown in the variable tables
"Sensor1" or "Sensor2", the process data of the IO-Link master in "PD IOLMM".
As mentioned above, please read the sensor documentation for the assignment of the
sensor’s SPDU-indices.
