Enabling Online Editing from a Programming Device
When online editing cannot be enabled from the program, it can be enabled
from the CX-Programmer.
1,2,3... 1. 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
turn OFF the Online Edit Disable Bit (A52709).
2. Performing Online Editing with a Programming Console
If online editing is executed from a Programming Console and the online
editing standby status cannot be cleared, the Programming Console will be
locked out and Programming Console operations will not be possible.
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.

If the Output OFF Bit (A50015) is turned ON through the OUT instruction or
from a Programming Device, all outputs from all Output Units will be turned
OFF (this applies to the built-in general-purpose or pulse outputs on CJ1M
CPU Units as well), and the INH indicator on the front of the CPU Unit will turn
ON.
The status of the Output OFF Bit is maintained even if power is turned OFF
and ON.
