A ladder program running on the CP2E can be edited online.
This can be done while the CP2E is in MONITOR mode or PROGRAM mode.
Using the CX-Programmer, it is possible to either change part of a ladder program running on the CP2E , or
make an addition to the program.
Online editing is used to make minor changes to the ladder program without actually stopping the oper-
ation of the CP2E.
Precautions for Correct UsePrecautions for Correct Use
• When a ladder program has been changed using online editing, the cycle time may increase
by one or more cycles, or it may not be possible to read an input signal.
• Major changes, such as moving a rung, copying, inserting, or deleting, should be done offline
and then the program should be transferred to the CP2E again.
• After completing online editing, the results of editing are backed up to backup memory, result-
ing in a longer cycle time. While this is being done, the BKUP indicator will be lit, and the
CX-Programmer will indicate the progress.
• An increase of one cycle will be 3.5ms maximum daring online editing and 8% of cycle time
during back up.
• Do not turn OFF the power supply to the CPU Unit after online editing, until the backup to the
backup memory is completed (the BKUP indicator is OFF).
