11 PROFINET Coupler Unit Functions
Overview
This function is used to read and set the IO Device Termi-
nal parameters from the Sysmac Studio. You can make
settings offline, or go online and read and set the Unit
configuration of the actual IO Device Terminal.
The PROFINET Coupler Unit exchanges IO data with the
mounted NX Units.
With this IO refreshing method, the refresh cycle of the
NX bus and the IO refresh cycles of the NX Units are
asynchronous.
This function is used to register NX Units that are not
connected to the actual configuration but will be added at
a later time in the Unit configuration information as
unmounted Units. If you use this function, you do not
have to modify the user program after the NX Units are
added.
This function records events, such as errors and status
changes, that occur in the Profinet IO Device Terminal.
This function initializes the entire Profinet IO Device Ter-
minal or specified Units from the Sysmac Studio.
This function allows you to apply changes to settings with
the Sysmac Studio or through special instructions, with-
out cycling the Unit power supply.
This function allows you to change the level of errors that
occur in the Profinet IO Device Terminal.
This function allows you to use the Sysmac Studio to
reset errors that occur in the Profinet IO Device Terminal.
This function allows the PROFINET Coupler Unit to start
or continue IO refreshing only with the NX Units that can
operate normally when an error occurs for the Profinet IO
Device Terminal.
Each of the PROFINET Coupler Units and NX Units
records the total time that the Unit power supply is ON to
it and the total times can be displayed on the Sysmac
Studio.
