Coding (hex) Status
0x00 No device error is present.
0x01
Failure (F):
A device error is present. The measured value is no longer valid.
0x02
Function check (C):
The device is in service mode (e.g. during a simulation).
0x04
Maintenance required (M):
Maintenance is required. The measured value is still valid.
0x08
Out of specification (S):
The device is being operated outside its technical specification limits (e.g.
process temperature range).
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.
