7.4.2
Process Data Qualifiers in Telegrams for PROFINET IO
7.4.2.1
One Byte IOxS Process Data Qualifiers
In cyclic telegrams, one byte process data qualifiers each are available for
PROFINET IO in the IO controller (IOPS) direction and in the IO device (IOCS)
direction for submodule types carrying the input or output data.
The amount of data in the real-time telegrams is always one byte more than the
respective process data length for these submodule types.
7.4.2.2
Two Byte IOxS Process Data Qualifiers
If the submodule types carry both input and output data, two byte process data
qualifiers each are available in cyclic telegrams for PROFINET IO in the IO
controller (IOxS) direction and in the IO device (IOxS) direction.
The amount of data in the telegram is always two bytes more than the respective
process data length for these submodule types.
7.4.2.3
Examples of One and Two Byte IOxS Process Data Qualifiers
•
Example 1:
Process data qualifiers for 2-channel digital input modules without
diagnostics and with diagnostics and diagnostic acknowledgement.

diagnostics and with 1-bit diagnostics and diagnostic acknowledgement.
