3 Safety Precautions
!WARNING The NE1A Logic Simulator simulates the safety logic of an NE1A Controller.
Operation and timing, however, vary somewhat from that of the NE1A Controller. After debugging safety logic on the NE1A Logic Controller, always debug
the safety logic directly on the NE1A Controller to verify operation. Debugging
only on the NE1A Logic Simulator may result in unexpected operation, possibly causing accidents.

The NE1A Logic Simulator Section 1-1
1-1 The NE1A Logic Simulator
The NE1A Logic Simulator provides an offline debugging environment on a
computer by simulating the safety logic operation of an NE1A-series Safety
Network Controller using only software. The NE1A Logic Simulator operates
on Windows 2000 or XP. Logic programs created with the Network Configurator (WS02-CFSC1-E) are loaded as files, and then the virtual safety logic
engine is started.
Hard Disk
*.smr
File
Network Configurator
Note (1) When a logic program that has been created with the Network Configu-
rator is exported from the Network Configurator, a simulation file (*.smr
file) will be created.
The simulation file will be loaded into the NE1A Logic Simulator and simulation will begin.
(2) Safety logic programs can be simulated only for one NE1A-series Con-
troller at a time. Multiple Controllers connected to the same network cannot be linked for simulations.

When the OK Button is clicked and the dialog box is closed, the settings
will be reflected in the program.
Note The tags in the Input Tag List can be set to ON or OFF by double-clicking
them.
34
Setting the Cycle Time Base Value Section 3-5
3-5 Setting the Cycle Time Base Value
The cycle time base value is a multiplier applied to the actual device cycle
time. When the cycle time base value is 1, the simulator runs based on the
same cycle time as the actual device. If the value is larger than 1, the simulation can be made slower than the actual device, so that delay times and discrepancy times can be checked. For example, if the delay function block is set
to 300 ms and the cycle time base value is set to 10, the delay in the logic
simulator will be 3 seconds.
Use the following procedure to set the cycle time base value. The setting cannot be changed if debug is being executed or paused.
1,2,3... 1. Select Debug - Cycle Time Base Value.
The following dialog box will be displayed.
2. Set the Cycle Time Base Value between 1 and 1,000, and then click the
OK Button.
The product of the cycle time and the cycle base value (ms) will become
one cycle of the debug process.
Note The cycle time is determined by the Network Configurator based on
the program size and other factors. It is only displayed for reference
in this window and cannot be modified.
Note (1) If the cycle time base value is set to a small value and the CPU perfor-
mance of the computer is low, CPU utilization will become high. When
this happens, it may create a time error in the input pulse or feedback settings. This may interfere with correct operation of the program. If this occurs, increase the cycle time base value to reduce the error.
(2) The cycle time base value set here does not affect debugging using the
Timing Chart Window.
35
Feedback Settings Section 3-6
3-6 Feedback Settings
If the EDM input (monitored input) is changed while the program is being executed when using EDM function blocks, the EDM feedback signal will not
change and will trigger a feedback error. Use the feedback settings to link the
reverse output signal to the EDM feedback signal in the EDM function block to
avoid feedback errors.
Note Feedback settings operate based on the Windows timer, which has error. The
error becomes larger particularly when the load on Windows is high. If this
happens, feedback error may occur even if feedback settings have been
made. To avoid feedback errors, make the cycle time base setting larger than
the current value.
Use the following procedure to set the feedback settings.
1,2,3... 1. Select Debug - Feedback Settings.
The Feedback Dialog Box will be displayed.
36
Item Description
Input Tag Specifies the input tag to be used in the feedback settings.
Output Tag Specifies the output tag that is linked to the input tag.
Delay Specifies the delay time between 50 and 1000 ms.
Condition Sets whether the value is reversed or not. Select the cell when
the reverse of the output tag is to be assigned to the input tag.

Overview Section 4-1
4-1 Overview
This section describes how to debug a program using the Timing Chart Window.
The debugging process starts with assigning input values to tags in the timing
chart, executing the logic program, then displaying the output results.
Pulses can be specified in terms of the device cycle time when using the Timing Chart Window. This makes it possible to run simulations for inputs that
fluctuate quickly, which is not possible when debugging with the logic window.
Note Debugging cannot be performed simultaneously using both the Timing Chart
Window and the Logic Window.
