4.2 Selecting the module versions
Introduction
The AI Energy Meter 480VAC ST has different module versions.
During the configuration you use the selection of the module version to specify which
measured values can be read.
Each module version supplies quality information via the input user data.
With the exception of the module version "2 I / 2 Q" you can read the measured values as
user data cyclically from the process image. At each module version you have the option to
read measured value records from the AI Energy Meter 480VAC ST by using the RDREC
instruction asynchronously.
Influence of the module version on the address space
Note
Influence of the AI Energy Meter 480 VAC ST on the maximum configuration of the
ET 200SP
The available address space of the ET 200SP is influenced by the following factors:
• CPU or interface module
• Plugged I/O modules
The address space made additionally available by the AI Energy Meter 480 VAC ST is
essentially influenced by the length of the user data supplied. The module version
determines the length of the user data, which can be supplied by the AI Energy Meter
480VAC ST at maximum.
