General Section
Section G1 Communication Mode Introduction
You can perform RS-232C/RS-485 communication between external devices by adding a communication board or unit to SPF.
Up to ve ports can be used (PORT 0 to 4). Port Nos. are dened according to the location of the SPF communication port.
For details, refer to “G1-2 About communication port”.
Select the communication mode in the parameter setting. The following four communication modes are available.
(1) General purpose communication
(2) Loader communication
(3) CPU link communication (SPF mode)
(4) Modbus RTU master communication
Note: The default parameter setting is “Loader communication”. Change the parameter setting for your purpose.
G1-1 Overview of Communication Modes
(1) General purpose communication
This communication mode allows data sending (or receiving) with external devices.
You need to create a communication program on the SPF side.

General Section
* Notes on executing resource initialization of the CPU by the loader using Port 1 to Port 4
Be aware of the following notes when you use PORT 1 to 4 as Loader connection.
If you execute resource initialization using PORT 1 to 4, set the parameter setting to “Loader” and download the project le to
the PLC before resetting the PLC.
If you execute resource initialization using PORT 1 to 4, and then reset the PLC before downloading the project le to the PLC,
loader communication is disabled. To release the disabled status, set the parameter setting to “Loader” and download the project
using PORT 0.
If you execute resource initialization using PORT 0, no need to worry about the notes above.
[Case where loader communication is disabled]
When you connect the loader to PORT1 to 4, and then execute “Resource initialization” -> “Reset”.
[Case where loader communication is not disabled]
When you connect the loader to PORT1 to 4, execute “Resource initialization”, set parameter setting to “Loader”, download the
project, and then reset the PLC.

G-4
General Section
(3) CPU link communication (SPF mode)
This communication mode enables data sharing between multiple CPUs (N-to-N communication). Data communication can be
performed simply by setting the station No. and area in the parameter setting. Only RS-485 is supported.
* CPU link communication specications of SPF are different from those of SPB/SPE. Therefore, the CPU link of SPF series
cannot be combined with that of SPB/SPE series

H1-5 Communication Cable Wiring
H1-5-1 RS-485 cable wiring
RS-485 provides connection for multiple stations. Its wiring distance must conform to the restriction specied in the EIA standard.
For hardware wiring, observe the principle that connection distance should be as short as possible and the station should be far
away from high noise sources.
RS-485 communication quality is affected and operation might be seriously interfered with if the problems, such as high baud
rate, long connection distance, high signal attenuation, multiple stations, bad grounding, high noise, terminating impedance
mapping, and topology, are not solved appropriately.
Read the notes of hardware wiring for RS485 network at the end of this section carefully.
<Limits on the number of stations>
The maximum number of stations for RS-485 interface is 16 (including self station).
<Limit on distance>
The following diagram shows the relationship between the baud rate and transmission distance of RS-485 standard interface.
