5. Enter the desired address in the associated "Start address" text field. Note the following:
– The I/O addresses must lie within the process image of the PLC (default setting: 1024
– Do not use any I/O addresses that are used for some other purpose, e.g. by the
– The I/O addresses must match the setting in the NC (SINUMERIK Operate).

Configuring the input delay for digital input modules

If you configure isochronous NC IO, you must correctly set the "input delay" value on the
used digital input modules. A small input delay shortens the response time, although a larger
input delay can possibly suppress longer interference pulses.
● You find the setting for the input delay for a selected digital input module under "Inputs" in
the "Properties" inspector window.
Configure the input delay appropriate for the send clock of the sync domain. The send clock
of the sync domain cannot be set smaller than the input delay of the digital input modules.
The default setting of the input delay is 3 ms.
