9.3.2 Description of the modules
The data structure is described from the perspective of the automation system:
• Input data: Are sent from the measuring device to the automation system.
• Output data: Are sent from the automation system to the measuring device.
Analog Input module
Transmit input variables from the measuring device to the automation system.
Analog Input modules cyclically transmit the selected input variables, along with the
status, from the measuring device to the automation system. The input variable is depicted
in the first four bytes in the form of a floating point number as per the IEEE 754 standard.
The fifth byte contains status information pertaining to the input variable.
