Mitsubishi FX/FX2N PLC
A. HMI factory settings
Baud rate: 9600, 7, EVEN, 1.
Controller Station number: 0. (no PLC station number in protocol, therefore, only 1(HMI) to 1 (PLC)
communication is allowed.)
Control area/status area: D0 / D10.
NOTE
1) If connecting to Mitsubishi FXxN series PLC, the user can use both FX2N and FX series communication
protocol.
2) If connecting to Mitsubishi FX series PLC, the user can only use FX series communication protocol.
3) Some registers of Mitsubishi PLCs are “read only”, however, when you write these “read only” registers,
PLCs will not report any communication error to HMI and this will cause HMI errors. Please be aware of
this when editing PLC program (this normally occurs when using FX series protocol when connecting to
a FXxN series PLC).
4) If connecting to Mitsubishi FXxN series PLC, it is recommended for the user to use FX2N protocol.
