Initial setup procedure
Configuration procedure
The following procedure shows the basic steps required before using the
PROFINET IO Communication Unit and the SmartSlice I/O Units.
1 Mount the GRT1-PNT Unit and the SmartSlice I/O system on the DIN rail.
The maximum number of SmartSlice I/O Units can be 64 (including GRT1-
END-M End Unit).
2 Wire the SmartSlice I/O Units and the GRT1-PNT Unit's power supply.
3 Wire the PROFINET IO network, to connect the Communication Unit to the
PROFINET IO Controller Unit.
4 Turn ON the power to the Unit and the I/O.
5 Turn ON (from OFF to ON) DIP switch 1 on the front of the PROFINET IO
Communication Unit. When switch 1 is turned ON, the existing SmartSlice
I/O Unit configuration (connection order and I/O size) is registered in the
PROFINET IO Communication Unit as a registered table. After the table is
registered, leave pin 1 ON to enable the table.
Note The next time the power is turned ON, the actual SmartSlice I/O Unit configuration at
power on is automatically compared to the registered table. Any SmartSlice I/O Units
that do not match the registered table (connection order or I/O size) will not participate
in I/O communication. I/O communication will start with the other SmartSlice I/O Units.
Use the following procedure to configure the IO Controller Unit together with
the PROFINET IO Communication Unit using CX-ConfiguratorFDT and the IO
Controller and IO Device DTMs:
1 Turn ON the PLC power supply and the power supplies of the IO Devices
on the network.
2 In CX-ConfiguratorFDT, create a network and define the parameters and
I/O configurations for the PROFINET IO Controller Unit settings and the
allocated IO Devices. Choose the update rate for each IO Device.
3 Use the PROFINET IO Controller DTM to assign Device Names to the
actual IO Devices in the network.
4 Download the network configuration to the PROFINET IO Controller Unit.
After downloading the configuration, CX-ConfiguratorFDT will restart the
PROFINET IO Controller Unit.
5 After restarting the PROFINET IO Controller Unit it will automatically start
communication when the PLC goes into RUN/MONITOR mode.
