Mitsubishi PLCs use a variety of data types to handle different kinds of information in automation programs. The basic types include Bit, which stores a single binary value (0 or 1), Word for 16-bit data, and Double-Word for 32-bit data. For signed numbers, they use DInt (32-bit integer), and for real numbers, Float is used. Text or character data is stored using the String data type, while Time data types handle values for timers and scheduling functions. These data types allow programmers to manage numeric, Boolean, text, and timing information efficiently in a Mitsubishi PLC.
Mitsubishi PLCs also organize these data types in specific memory areas. Data Registers (D) store 16-bit or 32-bit values, Internal Relays (M) and Latch Relays (L) handle Boolean logic and status signals, and Link Relays (B) connect different memory areas. Special registers exist for timers, counters, and other predefined functions. Using these data types correctly ensures the PLC program runs reliably, communicates data efficiently, and controls industrial processes effectively. Understanding Mitsubishi PLC data types is essential for programming, debugging, and maintaining automation systems in factories and industrial setups.
