Note 4: If “code conversion yes” of FB initialization parameter is selected, the transmission data becomes half number of

maximum words of each FB. Both “code conversion yes/ no”, usable data size is 512W which includes Start

code,

End code and BCC code. If data size exceed 512W, error occures.

Note 5: When you set port No. for the range of FB parameter, set down “1” for both RS-232C/RS-485.
