7.1.3 Addressing analog modules
Introduction
The addressing of analog modules is described below. In your user program, you require the
addresses of the channels of the analog module.
Analog module addresses
The address of an analog channel is always a word address. The channel address depends
on the module start address. The channel addresses are automatically assigned during
configuration in STEP 7. Based on the module start addresses, the assignment of the
channel addresses occurs in increasing sequence (in the following figure, the module start
address is 256).
When you insert an analog module into a free slot, STEP 7 assigns a default address. You
can change the assigned default address in STEP 7.
If you enable the value status for an analog module, then additional bytes are allocated in
the input address area. Each bit in this byte is assigned to a channel and returns information
about the validity of the analog value (0 = incorrect value).
