Totalizer module
The Totalizer module consists of the Totalizer Value, Totalizer Control and Totalizer Mode
submodules.
Totalizer Value submodule
Transmit transmitter value from the device to the automation system.
Totalizer modules cyclically transmit a selected totalizer value, along with the status, from
the measuring device to the automation system via the Totalizer Value submodule. 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 status information pertaining to the
totalizer value.

Status
Function check (C):
The device is in service mode (e.g. during a simulation).
Maintenance required (M):
Maintenance is required. The measured value is still valid.
Out of specification (S):
The device is being operated outside its technical specification limits (e.g.
process temperature range).
