Proline Cubemass C 100 PROFIBUS DP
Endress+Hauser
AI module (Analog Input)
Transmit an input variable from the measuring device to the PROFIBUS master (Class 1).
The selected input variable, along with the status, is cyclically transmitted to the
PROFIBUS Master (Class 1) via the AI module. 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 standardized status information pertaining to the input variable.
Eight Analog Input blocks are available (slot 1 to 8).
Selection: input variable
The input variable can be specified using the CHANNEL parameter.
