Omron CJ1W-PNT21, GRT1-PNT, CS1W-PNT21 Quick Start Manual

Profinet Quick Start Guide

Object of this guide

This quick start guide is to allow a new user to PROFINET to attach PROFINET I/O to an Omron PLC
and configure it to work.

PROFINET products supported in this guide

 CJ1W-PNT21 PROFINET I/O Controller for CJx series PLC’s
 CS1W-PNT21 PROFINET I/O Controller for CJ1 series PLC’s
 GRT1-PNT PROFINET I/O Device – Smart Slice Bus coupler.

Prerequisites

 A PC computer with both Serial/USB and Ethernet (via PROFINET) connection to Omron

PLC.

 Omron Cx-One V3.x or V4.x installed and up to date using Cx-One Auto Update utility. Cx-

One suite contains the utility application ‘Cx-Configurator FDT’ for configuring and setting
PROFINET devices.

 PLC & I/O Controller and IO Devices (at least one) for configuration.

I/O table on PLC should be created using Cx-Programmer.

Network

 It is recommended that the PROFINET network is ‘stand alone’. This means not part of a

larger network.

 The network speed must be 100MBaud. Using a 10BaseT hub will not allow the network to

operate correctly.

 If you wish to use switching hubs as part of the network, we recommend that these are

managed switches and of an industrial nature (e.g. Hirschmann).

Connection of devices for configuration

 To configure the I/O controller – use a serial or USB connection from PLC to PC.
 To configure the I/O devices – connect a network cable to the last I/O device (in case of

GRT1-PNT).

Configuration outline

1. Create IO Table in Cx-Programmer (fo r new Cx1W-PNT21)

2. Create the network topology in Cx-Configurator FDT

3. Set ‘names’ in real IO Devices using Ethernet connection (Search Devices)

4. Set same names of IO Devices to IO Controller in network topolo gy

5. Download Configuration of IO Devices to IO Controller (via Serial connection)

6. Restart system to finish configuration (IO Controller connects to IO Devices)

Create a network using Cx-Configurator FDT

Using Cx-Configurator FDT, open the Device Catalogue and show PROFINET IO. Highlight
PROFINET IO Controller (e.g. CJ1W-PNT21) and click ‘Add Device’.

Now add any IO Devices to the Controller (Controller must be highlighted in ‘MyNetwork’ tree).

Device Catalogue can be closed now.

Configure IO Device with correct set of IO Modules (Slices)

Double click on ‘iodevice1’ to configure the correct slices used in real system.
If GRT1-END-M is used, then this must be added as last slice – configuration error will occur if not.

Configure IO Controller and IO Device ‘names’

Open the IO Controller in the ‘tree’ (double click) and initial screen will be ‘PROFINET Identification’.
First operation is to use ‘Network Scan’ to ‘find’ devices on the Ethernet network. This is done by
searching for MAC addresses (so IP does not need to be configured at this point).

Once all devices have been recognised, the IO devices now require unique ‘Device names’ set. Use
the ‘Configure’ button and ‘Set Device Name’ option to give each IO device a name. The name is
used by the IO Controller at boot time to confirm existence and then allow configuration by the IO
Controller (setting IP address, etc.).

For example the IO Device now has the name ‘fred’
