The CJ1W-PNT21 PROFINET IO Controller Units perform an interface function between a PROFI-
NET IO network and the NJ CPU. On both sides of the interface different formats for data and data
storage are used.
To ensure that I/O data transferred through the interface can be used on both sides of the interface
without additional formatting, the CJ1W-PNT21 PROFINET IO Controller Units perform the neces-
sary data formatting. This ensures that I/O data in the CPU memory can be processed by standard
CPU Instructions and that the I/O data transferred to / from the PROFINET IO Devices over the net-
work is compliant with the PROFINET IO definitions.
Precautions for Safe Use
PROFINET IO Data types may not match the NJ-series Controller data types.
The table below lists the I/O data formats supported by both the PROFINET IO network and CPU.
