Note
4 byte are applied in the input and output
process image of the station proxy (field bus
coupler) by fitting the slot with this module
and are allocated to the physical module.
Two byte process data qualifiers (IOPS,
IOCS) are managed in the direction of the
I/O controller in the cyclic PROFINET IO
telegram for these modules.
6 byte are applied in the input and output
process image of the station proxy (field bus
coupler) by fitting the slot with this module
and are allocated to the physical module.
This module enables access to the register
structure of the I/O module for configuration
purposes.
Two byte process data qualifiers (IOPS,
IOCS) are managed in the direction of the
I/O controller in the cyclic PROFINET IO
telegram for this module.
