Ladder Logic is the primary programming language for PLCs (programmable logic controllers). Ladder Logic’s is a graphical programming language that uses symbols that resemble circuit diagrams and relay logic hardware. It resembles the rungs of a ladder between two horizontal power rails.
Our HMI+PLC (HMC) and PLC (MLC) configuration software MAPware-7000 offers more than one hundred Logic Block Instructions (commands used to create complex routines) for a variety of tasks. Ladder Logic is available in both the Native Ladder and IEC 61131-3 programming modes.
Ladder Logic Block instructions include routines for:
- Inputs and Outputs
- Data Transfers
- Mathematical Operations
- Comparisons
- Data Conversions
- Boolean Logic
- Timers
- Counters
- Complex Functions
- String Manipulation (Only available in IEC)
- Special Data Processing Functions (i.e., calculating the difference between the current time and date vs. a past time and date)
