Address assignment of the user data and the value status of the digital input module F-DI 16x24VDC
HA
The user data occupies the following addresses in the F-CPU out of all the assigned addresses of
the digital input module F-DI 16x24VDC HA:

Note
• You may only access the addresses occupied by user data.
• In S7 F/FH systems, the value status is automatically processed by the F-channel drivers.
• With I/O redundancy, you only access the channels of the left I/O module. The input values
of the corresponding channels of the redundant I/O module are automatically processed by
the F channel drivers.
• For 1oo2 sensor evaluation, the two channels are combined, e.g. channel 0 (input bit DI
with channel 8 (input bit DI
input bit of the lower channel number in the safety program, in this example channel 0.
• The other address areas occupied by the F-modules are assigned for functions including
safety-related communication between the F-modules and F-CPU in accordance with
PROFIsafe.
