Function name
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 Com-
munication Unit.
Automatic restore Automatically downloads the backed-up parameter data to the
appropriate Unit.
Online replacement I/O Units can be replaced without turning the power OFF.
I/O communication A history of communication errors with connected I/O Units can be
error history collected in the Communication Unit.

The following table lists the PROFIBUS Communication Unit's functions.
Summary
This function registers the configuration of the SmartSlice I/O Units connected
to the PROFIBUS 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 PROFIBUS 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 Com-
munication 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 regis-
tered in the table just by turning DIP switch pin 1 (REGS) from OFF to ON
while the PROFIBUS Communication Unit's power supply is ON. If the regis-
tration table is being refreshed, the old registration table will be erased.

Note The configuration information records the order that the SmartSlice I/O Units
are connected and the I/O size (input or output, number of bits) of each
SmartSlice I/O Unit. The I/O Unit model numbers are not recorded.
