Connecting Programming
Devices To connect a Programming Console, attach a CS-series Key Sheet and then
connect the Console to the CPU Unit’s peripheral port. (It cannot be con-
nected to the RS-232C port.)
3-8-3 Procedure for Creating an I/O Table
The procedure for creating an I/O table is shown here, taking as an example
an I/O table that is generated automatically for a PLC connected online. In this
example, a Programming Console is used for creating the I/O table. For an
explanation of how to create an I/O table using a CX-Programmer, refer to the
CX-Programmer User’s Manual .
Use the following procedure to create the I/O table.
3-9 Creating Routing Tables
When the FINS communications service is used, routing tables must be cre-
ated in advance. Routing tables are required in the following circumstances.
• When the FINS communications service is used on an FL-net network
(including when communications are only carried out between FA net-
works via an FL-net network).
• When there are multiple Communications Units mounted to the PLC, and
FA Link protocol messages, such as writing or reading word blocks, etc.,
are executed by the CMND(490) instruction.
If neither of these circumstances apply, then a routing table is not required. In
that case, proceed to
3-10 System Setup .
The routing table is required not only for nodes communicating via the FINS
communications service but for all relay nodes on the network.
