Differences In The Replacement Value Behavior - Siemens Simatic ET 200S Operating Instructions Manual

Diagnosis "Process interrupt lost"
For the modules
• 2DI 24 VDC HF (6ES7131-4BB01-0AB0),
• 4DI 24 VDC HF (6ES7131-4BD01-0AB0) and
• 4DI UC24..48V HF (6ES7131-4CD00-0AB0)
the diagnostic "Process interrupt lost" is not available at present.
Note
Process interrupts should not be used for technological purposes (e.g. cyclical generation of
process interrupts).
If more than 90 process interrupts are generated per second, process interrupts may be lost.

Differences in the replacement value behavior

Replacement value behavior station granular with 6ES7151-3AA00-0AB0
If you use an interface module 6ES7151-3AA00-0AB0 in the IO device, the following
replacement value behavior is displayed:
• All output modules output their parameterized replacement values or "0" on their outputs.
Replacement value behavior slot granular from 6ES7151-3AA10-0AB0 or 6ES7151-3BA20-0AB0
If you use an interface module 6ES7151-3AA10-0AB0 or 6ES7151-3BA20-0AB0 in the IO
device, the following replacement value behavior is displayed:
• All outputs whose reference data companion are "Bad", output their parameterized
