Creating a I/O table
Creating a FINS Routing table
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
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.
