Trial Operation and Debugging
Task Size and Cycle Time
Extension
Operating in
MONITOR mode.
The cycle time will be increased by from one to several cycle times if the pro-
gram in the CPU Unit is edited online in MONITOR mode.
The cycle time will also be increased to back up data in the flash memory after
online editing. The BKUP indicator will be lit during this period. The progress
of the backup is displayed on the CX-Programmer. The increases per cycle
are listed in the following table.
Note The CS1G/H-CPU@@ (-V1) and CJ1@-CPU@@ CPU Units do not support the
flash memory functions.
CPU Unit
CS1 CPU Units pre-EV1
CS1 CPU Units EV1 or higher 12 ms max.
CS1-H CPU Units
CS1D CPU Units
CS1 CPU Units
CJ1-H CPU Units
CJ1M CPU Units
There is a limit to the number of edits that can be made consecutively. The
actual number depends on the type of editing that is performed, but the follow-
ing can be used as guidelines.
CJ1M-CPU@@:
CS1G-CPU@@H/CJ1G-CPU@@H:
CS1H-CPU@@H/CJ1H-CPU@@H/CS1D-CPU@@H/
CS1D-CPU@@S:
A message will be displayed on the CX-Programmer or Programming Console
if the limit is exceeded, and further editing will not be possible until the CPU
Unit has completed backing up the data.
Note This limit does not apply to the CS1G/H-CPU@@ (-V1) and CJ1@-CPU@@
CPU Units.
The relation to the size of the task being edited to cycle time extension is as
follows:
When using a version 1 or higher CS1 CPU Unit, CS1-H CPU Unit, CS1D
CPU Unit, CJ1 CPU Unit, or CJ1M CPU Unit, the length of time that the cycle
time is extended due to online editing is almost unaffected by the size of the
task (program) being edited.
