2.3 Special considerations for use on the PROFIBUS DP and PROFINET IO

PROFIBUS DPV 0
If the DP Master does
not
support DPV1, you cannot reassign parameters which results in
the following restrictions:
● There are no phase-specific parameters. All parameters apply for all three phases and
the neutral conductor.
● The connection types und user data variants are limited.
● The voltage transformers are not configurable (default: 1:1).
● The current transformer value range primary current is restricted.
● The low limit for measuring current cannot be adjusted (default: 50 mA).
● Energy metering is performed continuously (the gate is not enabled).
● Min/Max calculation of values is enabled (the gate is not enabled).
● 3P4W can be set in the parameters for the connection type 3P3W.
● 3P4W can be set in the parameters for the connection type 3P3W1.
● Counting of operating hours is enabled (the gate is not enabled).
● The residual current measurement is enabled.
● Limit value monitoring cannot be used.
● Energy meter default cannot be used.
● The user-defined user data interface cannot be used.
● The user-defined data record cannot be used.
● The power quality analysis cannot be used.
● The separate settings for measuring the neutral current cannot be used.
● The measured value data records cannot be used.
Operation of the module on PROFINET IO
When reading data records partially from the module, please note the following:
● Measured value data record DS 142:
– When you read the data record with a length of 240 bytes or less, the module returns
the measured value data record DS 142 in version 2.
– When you read the data record with a length of more than 240 bytes, the module
returns the measured value data record DS 142 in version 3.
● Measured value data records DS 147, DS 148, DS 149:
– When you read the data record with a length of 240 bytes or less, the module returns
the measured value data record in version 0.
– When you read the data record with a length of more than 240 bytes, the module
returns the measured value data record in version 1.
