In this case, connect the CX-Programmer to another serial port and turn
OFF the Online Edit Disable Bit (A52709). The online editing will be pro-
cessed and Programming Console operations will be possible again.
2. Performing Online Editing with the CX-Programmer
If operations continue with online editing in standby status, CX-Program-
mer may go offline. If this occurs, reconnect the computer to the PLC and
