The Step Run allows to debug by step, which was impossible in debugging
using an actual CS/CJ PLC.
In addition, combining execution with a break/start point specified, and break
with I/O memory conditions (I/O break conditions) specified will allow closer
debugging.
The Step Run is available only for a program on the program area for appli-
cations (UM1), not for debugging (UM2).
The Ladder Engine accepts and process FINS commands even during a cy-
cle execution as long as it is during pausing (e.g. Step Run).
This enables monitoring the values during a cycle execution, which is usually
impossible.
When performing Online Editing to the Ladder Engine during Step Run or
pausing during a cycle, the program execution returns to the status just prior
to the cycle start and pauses (when set as Online Editing enabled for Scan
Rerun/Step Run).
The cycle time during Step Run (including pausing), for both virtual cycle time
and computer cycle time, does not include the time of pausing. Similarly, the
Timer, Clock Pulses, etc. do not operate during pausing. However, only the
time clocks the actual time if set as "computer cycle time." If set as " virtual
cycle time", the time stays unchanged during pausing because the time ac-
cumulates the virtual cycle time.
