5.2 Programming Tool Applicability
5.2.3 Program transfer speed and programming tools
1. Built-in USB communication
The FX3S PLC has a built-in USB communication port, and performs program writing, program reading and
monitoring at high speed (12 Mbps) with a personal computer that supports USB.
1) Supported programming tools
*1
GX Works2, GX Developer
2) In programming tools not supporting USB
Communication is performed via RS-422 or RS-232C.
2. RS-422/RS-232C communication
The FX3S PLC can write and read programs and perform monitoring at 115.2 kbps through RS-422/RS-232C
communication.
1) 115.2 kbps supported programming tools
*1
GX Works2, GX Developer, FX-30P
2) 115.2 kbps supported interfaces
- Standard built-in port (RS-422) or expansion board FX
3G-422-BD for RS-422
When the RS-232C/RS-422 converter FX-232AWC-H is connected.
- Expansion board FX
3G-232-BD for RS-232C
- Special adapter FX
3U-232ADP(-MB) for RS-232C
3) In programming tools not supporting 115.2 kbps
Communication is executed at 9,600 or 19,200 bps.
*1. When the currently used programming tool does not support the FX
3S PLC, use a programming tool
which allows selection of the FX
3G PLC as the alternative model.
5.2.4 Cautions on connecting peripheral equipment by way of expansion board or
special adapter
When connecting peripheral equipment (programming tool or GOT [CPU direct connection]) by way of the
FX
3G-232-BD, FX3G-422-BD or FX3U-232ADP(-MB), set as follows. If the setting is not specified with the
status below, communication error may occur in the connected peripheral equipment.
For details, refer to the Data Communication Edition.
- Set to "K0" the special data register (D8120 or D8400) for communication format setting.
- Set the communication parameter "PLC system(2)" of the channel connecting the peripheral equipment
to "Not set" (as shown in the window below).
Leave this unchecked.
