Ladder Diagram Integration

Import, simulate, and validate your existing ladder diagrams. Model, simulate, and generate code using the provided Ladder Diagram blocks and functions.

Ladder Diagram is a graphical programming language that you use to develop software for programmable logic controllers (PLCs). It is one of the languages that the IEC 61131 standard specifies for use with PLCs. A program in ladder diagram notation is a circuit diagram that emulates circuits of relay logic hardware. The underlying program uses Boolean expressions that translate readily to switches and relays.

With金宝app^®PLC Coder™, you can use ladder import to import ladder diagrams created with Rockwell Automation^®IDEs, such as RSLogix™ 5000 and Studio 5000 into the Simulink environment as a model. You can create ladder diagrams in the Simulink environment as a model.

After importing or creating the ladder diagram models, you can:

Edit the imported Ladder Diagram model from within Simulink by using theplcladderliblibrary.
After importing the ladder diagram code into Simulink, simulate it.
Generate C code from the imported ladder diagram and integrate the code into your existing C language-based simulation environments.
Generate ladder diagram code from the imported ladder diagram and integrate the code into your Rockwell Automation IDE. You cannot generate structured text code from the Ladder Diagram blocks.
Generate PLC testbench code for the imported ladder diagram and verify the code in your Rockwell Automation IDE.

Simulate, Model, and Generate Code for Timer-Based Ladder Logic

Model and simulate ladder logic for a simple timer-based motor controller. The ladder logic based controller uses an on-delay timer to delay the start of the motor and an off-delay timer to delay the stopping of the motor. After verifying that the controller and timers function for your requirements generate code for the controller.
