Data structure
Output data of Analog Output
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5
Measured value: floating point number (IEEE 754) Status
DI module (Discrete Input)
Transmit discrete input values from the measuring device to the PROFIBUS master (Class
1). Discrete input values are used by the measuring device to transmit the state of device
functions to the PROFIBUS master (Class 1).
The DI module cyclically transmits the discrete input value, along with the status, to the
PROFIBUS Master (Class 1). The discrete input value is depicted in the first byte. The
second byte contains standardized status information pertaining to the input value.
Two Discrete Input blocks are available (slot 9 to 10).
Selection: device function
The device function can be specified using the CHANNEL parameter.

Discrete Status
DO module (Discrete Output)
Transmit discrete output values from the PROFIBUS master (Class 1) to the measuring
device. Discrete output values are used by the PROFIBUS master (Class 1) to enable and
disable device functions.
The DO module cyclically transmits the discrete output value, along with the status, to the
measuring device. The discrete output value is depicted in the first byte. The second byte
contains standardized status information pertaining to the output value.
Three Discrete Output blocks are available (slot 11 to 13).
