Table Registration Function
Function Overview
This function registers the configuration of the Slice I/O Units connected to the
DeviceNet Communications Unit in a table within the Unit, so that the regis-
tered I/O table can be automatically compared with the actual configuration
each time that the power is turned ON. The configuration is registered simply
by turning ON (OFF to ON) pin 1 of the DeviceNet Communications Unit’s DIP
switch while the Slice I/O Terminal’s power supply is ON. The registered table
is enabled if pin 1 is ON when the power is turned ON. If pin 1 is OFF when
the power is turned ON, the registered table is disabled and the Communica-
tions Unit will automatically detect the actual I/O configuration and start com-
munications.
Creating a New
Registration Table
The Slice I/O Terminal’s present I/O configuration can be read and registered
in the table just by turning DIP switch pin 1 (REGS) from OFF to ON while the
DeviceNet Communications Unit’s power supply is ON. If the registration table
is being refreshed, the old registration table will be erased.
Note
The configuration information shows the order that the Slice I/O
Units are connected and the I/O size (input or output, number of
bits) of each Slice I/O Unit. The I/O Unit model numbers are not re-
corded.
I/O communications
error history
A history of communications errors with connected I/O Units can
be collected in the Communications Unit.
Set/read with Configurator or
explicit message.
Last maintenance
date
The date on which maintenance was performed can be written to
the Communications Unit.
Set/read with Configurator or
