The RS-422 communication board FX1N-422-BD (hereafter reaferred to as "422BD") is connected to the FX1S/FX1N
Series PLC basic unit, and used as a connection port for a programming tool (such as the GOT Series, the ET Series,programming tool FX-10P/20P or personal computer).
For example, by using the 422BD, two GOT Series units can be connected to the FX1S/FX1N Series PLC, or the GOT Series unit can be connected to a programming tool (such as FX-10P, FX-20P or personal computer). However, a programming tool can be connected to only either one between the connector built in the PLC and the connector of the 422BD.
Only one function expansion board can be connected to one PLC basic unit. Accordingly, the 422BD cannot be used together with the FX1N-485-BD or the FX1N-232-BD.
