Addressing the S7-400

Default Addresses of Analog Modules

On the S7-400, the default addresses for analog modules start from 512 (first slot in the central rack which is usually occupied by the power supply module) up to 1600.

The algorithm used to calculate the default address of an analog module is: Default address = (slot number - 1) x 64 + 512

Example

The default address of an analog module in the 6th slot is as follows:

Default address = (6 - 1) x 64 + 512 = 832
