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).
Typical Initial Connection diagram
Serial for configuration of IO Controller
Ethernet for configuration of IO Devices
