5.2.2.3 Addressing analog electronic modules
Introduction
The following section describes the addressing of analog electronic modules. You need the
addresses of the channels of the analog electronic module in the user program.
Analog module addresses
The address of an analog channel is always a word address. The channel address depends
on the module start address. STEP 7 assigns the channel addresses automatically during
configuration. Based on the module start addresses, STEP 7 assigns the channel addresses
in ascending order. The figure below shows the module start address 256.
When you insert an analog electronic module into a free slot, STEP 7 assigns a default
address. You can change the proposed default address in STEP 7.
