Data transfer with FX
2N
, FX
2NC
, FX
1N
, FX
1S
, FX
0N
programmable controllers can be
performed on a N:N basis. They can link data of a small-scale system if using this network.
For the system configuration please refer to subsection 1.2.1, specifications refer to chapter
3, wiring refer to chapter 2, settings and the number of transferred data and example
program refer to chapter 4,diagnostics refer to chapter 12.
2 ) Parallel link
Data transfer with FX
2N
, FX
2NC
, FX
1N
, FX and FX
2C
programmable controllers can be
performed on a 1:1 basis for 100 auxiliary relays and 10 data registers. With the FX
1S
and
FX
0N
data transfer is performed for 50 auxiliary relays and 10 data registers.
For the system configuration please refer to subsection 1.2.2, specifications refer to chapter
3, wiring refer to chapter 2, setting and example program refer to chapter 5, diagnostics refer
to chapter 12.
3 ) Computer link (Data transfer using dedicated protocol)
Data transfer with RS-485 (RS-422) units can be performed on a 1:n (16) basis using
dedicated protocol.
For the system configuration please refer to subsection 1.2.3, specifications refer to chapter
3, wiring refer to chapter 2, setting of communication format refer to chapter 6, dedicated
protocol refer to chapter 7 & 8, diagnostics refer to chapter 12.
4 ) No protocol communication (Data transfer using RS instruction)
Data communication with a diversified RS-232C unit including personal computers, bar code
readers and printers can be performed using no protocol communications.
This communication uses RS instruction’s or an FX
2N
-232IF special function block.
For the system configuration please refer to subsection 1.2.3, specifications refer to chapter
3, wiring refer to chapter 2, setting of communication format, RS instruction and example
program refer to chapter 6 and 9, diagnostics refer to chapter 12.
