1. Outline of Product
The RS-485 communication board FX
1N
-485-BD (hereafter referred to as "485BD") is connected to the
FX
1S
/FX
1N
Series PLC basic unit, and available for the applications described below.
Only one function expansion board can be connected to one PLC basic unit. Accordingly, the 485BD cannot
be used together with the FX
1N
-422-BD or the FX
1N
-232-BD.
1.1 Features
1) Data transfer function using the non-procedure method.
The 485BD transfers the data using the RS instruction between a bar code reader, personal computer
or printer.
As the 485BD is not equipped with buffer memory, it sends and receives the data using data registers
specified by the RS instruction.
For the RS instruction and the communication setting, refer to the FX Series Communication User’s
Manual.
2) Data transfer function using a dedicated protocol.
The 485BD transfers the data when a personal computer directly specifies devices of the PLC.
For the dedicated protocol and the communication setting, refer to the FX Series Communication
User’s Manual.
3) Parallel link function.
The 485BD transfers automatically 50 auxiliary relays and 10 data registers when two FX
1S
Series
PLC’s (two FX
1N
Series PLC’s) are connected on a one-to-one basis.
For the setting procedure and program examples, refer to the FX Series Communication User’s Manual.
4) Easy PC link function.
The 485BD transfers automatically up to 64 auxiliary relays and 8 data registers when up to eight FX
