3. Outline of Communication Setting in the FX Series
This chapter describes which communication parameters can be changed for the following communication
types, and provides methods on how to change them.
• Computer link
• Inverter communication
• Non-protocol communication (RS/RS2 instruction)
• Internet mail sending
3.1
Setting Method
The following two communication setting methods are available for FX PLCs. Either method can be used, but
the method using parameters is recommended.
1. Setting methods
1) Specify the settings using parameters in the programming tool
Register the settings in parameters, transfer it to the PLC and turn the PLC's power OFF and then ON.
(This method is not available in FX
2
(FX), FX
2C
, and FX
0N
PLCs.)
(This method is not available for ch0 in FX
3G
, FX
3GC
PLCs.)
2) Directly specify the settings in a sequence program
Prepare a sequence program which sets the communication format, station number and time-out time
setting, and then transfer the program to the PLC.
Caution
Regardless of the method chosen above, a PLC operates the same way. If both methods are selected,
priority is given to the method using parameters.
