Description
Detects IO devices on the same network as the RJ71PN92 and obtains the number of
connected IO devices.
Obtains detailed information of the IO device that has been detected by the network
detection.
Reads the specified data from the IO device where the PROFINET module has not been set
in the RJ71PN92.
Writes the specified data to the IO device where the PROFINET module has been set in the
RJ71PN92.
Reads the specified data from the IO device where the PROFINET module has been set in
the RJ71PN92.
Reads information of an alarm that has currently occurred in the specific IO device.
