Siemens SIMATIC S5 Manual page 84

The four pages of a module must have consecutive numbers. The addresses for the following
pages are calculated automatically by the IP247, after you have set the base address.
When supplied, each module is set with the same address area for the page number (switch S1
and jumpers Xl 4, Xl 5 and Xl 6).
Address area OF400H to OF7FFH (61 Kto62 K-1)

You must set the page number of the module (even-numbered base address of the first axis) be-
tween O and 252 in stem of four, using switch S2.

The page addresses 85, 86, 87 for the following pages are automatically decoded by the module.
The first page address of the next module can then be set to 88.
Disable Command Output
The BASP signal (disable command output), which is triggered by the PC (e.g. when it changes
to STOP or if the load voltage drops below 15 V), can be used to disable the digital outputs on
the module.
