Number of decimal digits

is the default setting. This means that the number of digits after the decimal point automatically
will be reduced with increasing number of digits before the decimal point.

Password-protected data

In the Modbus communication via SIMATIC PDM, the flowmeter information is protected by a
password. The default password is "1000" and it can be changed after gaining access to the
flowmeter or via the PDM menu [Device → Change Password (Online)]. The password can be
changed without the use of the HW key.
