Initial Setup Procedure

3-3-1 Creating a I/O table
3-3-2 Creating a FINS Routing table
After mounting the PROFINET IO Controller Unit to the PLC System the Initial
Setup Procedure must be applied. The Initial Setup Procedure allows the Unit
to start up properly and to be configured for operation.
• Before the PLC's power supply is turned on a unique Unit number must be
set.
• An I/O table must be created in the PLC, to register the Unit on the PLC
CPU.
• If forwarding of FINS messages is used, the CJ1W-PNT21 needs a FINS
Routing table. This must be created.
An I/O table identifies any Units connected to the PLC and to allocate PLC
memory areas to each of these Units. The I/O table is stored in the PLC CPU
and loaded at start up. If any change is made to the Unit configuration of a CJ-
series PLC, the I/O table must be created again to identify the Units to the
CPU Unit.
To create the I/O table, connect a PC with CX-Programmer or CX-Integrator
installed to the PLC.
For details regarding creation of the I/O Table using CX-Programmer or CX-
Integrator, refer to the CX-Programmer User's Manual or CX-Integrator User's
Manual.
After creating the I/O table, the Unit is ready to be configured for first use on
the PROFINET IO network.
A FINS Routing table is used to forward FINS messages from one network to
another. The CJ1W-PNT21 supports FINS/UDP communication and can be
used to forward FINS-messages.
A FINS Routing table must be created if message transfer via other
communication units
Communication Unit), CJ1W-SCU (Serial Communication Unit) or CJ1W-
DRM21 (DeviceNet Communication Unit). It is very important to assign a valid
network number to the CJ1W-PNT21.
If a FINS Routing table exists but there is no entry for the CJ1W-PNT21, the
CJ1W-PNT21 will operate normally. However, forwarding FINS messages
through the CJ1W-PNT21 will not be possible.
