8.3.2 Description of the modules
The data structure is described from the perspective of the automation system:
• Input data: are sent from the device to the automation system
• Output data: are sent from the automation system to the device
Module: Analog input
Transmission of input variables from the device to the automation system:
Analog input modules cyclically transmit the selected input variables, including the status,
from the 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. The Analog input module
Level in slot 1 is contained in the Level PA PROFILE GSD, the other Analog input modules
can only be used with the manufacturer's GSD.
Module: Binary output
The Binary output module can cyclically receive discrete output values from the
automation system. The device implements an 8-bit type as described in PA PROFILE 4.0x.
Of this, 1 bit is used to signal to the device that Heartbeat Verification should be started.
