Additional Information
When turning on the power supply to the Controller, an I/O Setting Check Error occurs when
there is a Unit Configuration in the CPU Unit which does not match the actual Unit Configuration.
In this case, reset the Controller after transferring the Unit Configuration to cancel the error.
Use the following procedure to configure the PROFINET IO Controller and PROFINET IO Devices
using CX-ConfiguratorFDT.
1
Turn ON the CPU power supply and the power supplies of the IO Devices on the network.
2
Use the PROFINET IO Controller DTM's Network Scan function to assign Device Names to the
actual IO Devices in the network.
3
In CX-ConfiguratorFDT, create a network and define the parameters and I/O configurations for
the PROFINET IO Controller Unit and the allocated IO Devices. Choose the update rate for
each IO Device.
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 restart of the PROFINET IO Controller Unit, communication with the PROFINET IO
Devices will start automatically.
With this Unit, the IO Device areas are allocated to the Memory used for CJ-series with user-set alloca-
tions.
The user program accesses the slave via the user-defined variable that specifies the AT specification
for the area where the slave is allocated. With this Unit, the device variable for CJ-series Unit, or a user
defined variable that specifies the AT specification of the allocation area for the slave is setup using the
CX-ConfiguratorFDT software application. User-defined variables are created using Sysmac Studio.
Have the necessary user-defined variables created before creating a program.
For details on operations, refer to the
Sysmac Studio Version 1 Operation Manual
(Cat. No. W504).
Precautions for Correct Use
Precautions for Correct Use
The user is responsible for management of the memory used for CJ-series Unit. Please take
great care to avoid overlapping of reference areas between user-defined variables.
