C.3 "User-specific" module version
Analog input module AI Energy Meter 480VAC ST (6ES7134-6PA20-0BD0)
Manual, 12/2015, A5E36061895-AA
131
"User-specific" module version
User data of the module
The module occupies between 16 and 256 bytes of input user data and 12 bytes of output
user data. Of these the module uses 2 bytes input data for status information and 12 bytes
output data for control information. Measured variables can be read cyclically via user data
(as of Byte 2) or acyclically via measured value data records
Structure of input user data
You configure the structure of the input user data starting at Byte 2 at this module version
itself. An input user data length of 32 bytes also allows you to set the input user data
dynamically. You can choose between different user data variants.

Quality bits to describe the quality of the basic measured values
2 ... 255 Module or phase Data Measured values or calculated values in accordance with their con-
figuration:
• At configuration in STEP 7 the size of the input user data is calcu-
lated automatically.
• At configuration via the GSD file the size of the input user data
amounts to 32, 64, 128 or 256 bytes. The memory area has to be
sufficiently large for the measured variables defined in parameter
data record 130.
