In the industrie the PLC is the most important device because of is role, it's the responsible of all the process in the automatization industry, in other words is the brain. But this brain doesn't work if there's no tasks to do, so the PLC need some kind of code or language that it understand in order to do some tasks.
One of the languages that the PLC understand is the Ladder Diagram, this is a graphic language that represents the logic of relay circuits.

PLC Ladder Simulator is a simulator for the Android OS with input and output objects that simulates the I/O port of a real PLC. You can create your designs with the basic components of a ladder diagram, which are five for this version: normally open gate (N.O.), normally closed gate (N.C.), Coil, Counter and Timer.

PLC Ladder Simulator PRO features an unique option available in the world and it's the possibility of program an Arduino board with a ladder design using an Android phone. So actually what it does is that transforms an Arduino into a PLC (Programmable Logic Controller). The app writes a code into the Arduino by using an USB OTG cable.

The Arduino mode it's compatible with the Arduino UNO (atmega328), MEGA (atmega2560) and NANO (atmega328). This feature is still in BETA version, may have some issues, please report any bug sending an email at: casdata@gmail.com

The Pro version features compared with the Free version are:

- NEW component: Counter.
- NEW component: Timer.
- Arduino mode
- 10 save slots for keep more designs with slot name customization.
- Auto-save slot.
- No Ads.

Tutorial on how to use the Arduino mode can be found at: http://casnisoft.co.nf/plcpro.html

Before you buy this version you can try the FREE version to ensure that your device is compatible.
