6.5.4.14 MC_ReadDigitalInput_ISD51x
This function block provides the value of the specied
input. It is not guaranteed that pulses shorter than the
eldbus cycle time on the digital signal can be seen on the
function block.
The output data is available immediately.

6.5.4.15 DD_ReadAnalogInput_ISD51x
This function block reads the value of the analog input.
The output data needs to be read from the device and is
therefore not immediately available.
