Recommendations for selecting the module version
The following table shows which module version is suitable for a given purpose.

Note
2 I / 2 Q
• Use of many AI Energy Meter
HF in an ET 200SP or little
address space is available
• Read the measured values solely via the RDREC instruc-
tion from a measured value data record.
• Quality information about the measured values is always
available.
EE@Industry measu-
rement data profile
E0 / E1 / E2 / E3
• Cyclic measurement per
phase
• Supplied measured values in
accordance with the
EE@Industry measured data
profile
• Available measured values depend on the configured
measurement data profile.
• The user data are fixed and cannot be changed dynami-
cally. Alternatively, read the measured values acyclically
from a measured value data record via the RDREC in-
struction.
• No quality information
32 I / 20 Q
• Cyclic measurement per
phase
• Flexibility by switching prede-
fined user data variants
• Quality information about the measured values is always
available.
• Depending on the user data variant, you must convert
the measured values in the CPU to physical values using
the supplied scaling factor.
• One cycle elapses for each user data changeover.
Measured values from the next user data variant are thus
supplied with a slight time offset.
Alternatively, read the measured values acyclically from
a measured value data record via the RDREC instruc-
tion. Consistent measured values of a measuring cycle
are supplied.
User-specific
• Cyclic measurement of up to
64 measured values configu-
rable
• Flexibility by switching prede-
fined user data variants
With GSD configuration
• 32 I / 20 Q
• 64 I / 20 Q
• 128 I / 20 Q
• 256 I / 20 Q
