Features
Unlike with VisiLogic where you need the actual hardware to do simulations and testing, you can use i-TriLOGI
for simulating your ladder logic diagrams (LLD). However, it has limited functions available.
Available:
• Input/output
• Relays, timer (time delay), counters
• Set/reset
Limitations: i-TriLOGI DOES NOT HAVE the following functions you use in VisiLOGIC:
How to Use
i-TriLOGI interface looks like the image below.
If you just want to see the I/O Labels again, just click the I/O Table button (Fig 5).
Increment #3 INCtr
Simulation
To simulate the simple LLD in Fig 7, click Simulate > Run (All I/O Reset). Then, Programmable Logic Simulator
(Fig 8) would show up.
To press the input buttons, left-click on it. To hold the input, right-click on it. Fig 8 shows that when both PB1
and PB2 are pressed, the output O1 turns on.
Sample #1
In the sample LLD below, whenever PB1 is pressed, the counter value changes. When it reaches the preset
value of 5, RLY A turns ON. PB2 resets the counter.
In VisiLogic, you use the INC (increment) or DEC (decrement) block to add or subtract the counter value. With
VisiLogic, it usually starts from 0 and counts-up to the preset value. It can even go beyond the preset value.
When the counter reaches the preset, that’s when it turns ON.
In i-TriLOGI, you can use an output coil for the counter. The default is that it starts from the preset value and
counts-down to 0. It doesn’t go below 0. When the counter reaches 0, that’s when it turns ON.
VisiLogic i-TriLOGI
• If C1 >= 5, RLY A turns ON • If C1 == 0, RLY A turns ON
• PB2 resets C1 • PB2 resets C1
Sample #2
If you want to add and subtract values to the counter in i-TriLOGI, use the [Fn] ([INCtr], [DNCtr]). Take note, if
using the [Fn] for counter, you can’t use the output coil ( ).
Unlike with the previous sample where the value of C1 remains at 0 unless it resets, using [Fn] cycles the value
between 0 and the preset. This mean, when the value reaches 0, decrementing again makes the counter value
equal to 5. When the value is at 5, incrementing again makes the counter value equal to 0.
The problem with using this is that the contact corresponding to this counter does not necessarily turn ON
when the value is 0. There are two ways that can turn on the counter. From the sample i-TriLOGI LLD below:
When you run the sample below, you’ll also notice that RLY A turns ON after 6 presses (either PB1 only or PB2
only), not 5.

• If C1 >= 5, RLY A turns ON • If using [INCtr], RLY A turns ON when C1 == 0.
• If PB1 is pressed, add 1 to • If using [DNCtr], RLY A turns ON when C1 == 5.
the value of C1. • If PB3 is pressed, reset C1.
• If PB2 is pressed, subtract 1
to the value of C1
• If PB3 is pressed, reset C1.
Timer Implementation
The time delay function in VisiLogic is the same as the timer function in i-TriLOGI. There are no time
accumulate (TA) and time extend (TE) in i-TriLOGI.
In using i-TriLOGI, just take note that the speed timer is not accurate. The i-TriLOGI runs much faster. A 5-
second counter may finish in 1 second. Don’t worry too much about this as long as you the diagram is correct.
