Measured value: floating point number (IEEE 754) Status
TOTAL module
Transmit a totalizer value from the measuring device to the PROFIBUS master (Class 1).
Via the TOTAL module, a selected totalizer value along with the status is cyclically
transmitted to a PROFIBUS master (Class 1). The totalizer value 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 totalizer value.
Three totalizer blocks are available (slot 5 to 7).
Selection: totalizer value
The totalizer value can be specified using the CHANNEL parameter.

SETTOT_TOTAL module
The module combination consists of the SETTOT and TOTAL functions:
• SETTOT: Control the totalizers via the PROFIBUS master.
• TOTAL: Transmit the totalizer value along with the status to the PROFIBUS master.
Three totalizer blocks are available (slot 5 to 7).
