Function name Summary
Table registration Reads the configuration of the
SmartSlice I/O Units connected to
the Communication Unit and
registers that information in a table.
Backup Records the parameter data of all
connected I/O Units in the
Communication Unit.
Automatic restore Automatically downloads the
backed-up parameter data to the
appropriate Unit.
On-line replacement I/O Units can be replaced without
turning the power OFF.
I/O communication A history of communication errors
error history with connected I/O Units can be
collected in the Communication
Unit.
This function registers the configuration of the SmartSlice I/O Units connected
to the PROFINET IO Communication Unit in a table within the Unit, to allow
the registered I/O table to be compared automatically with the actual
configuration each time the power is turned ON. The configuration is
registered by turning ON (OFF to ON) DIP switch 1 of the PROFINET IO
Communication Unit while the SmartSlice I/O Units' power supply is ON. The
registered table is enabled if DIP switch 1 is ON when the power is turned ON.
If DIP switch 1 is OFF when the power is turned ON, the registered table is
disabled and the Communication Unit will automatically detect the actual I/O
configuration and start communication.
The SmartSlice I/O System's actual I/O configuration can be read and
registered in the table just by switching DIP switch 1 (REGS) from OFF to ON
while the PROFINET IO Communication Unit's power supply is ON. If the
registration table is being refreshed, the old contents will be erased.
