Omron I/O Interface Unit CS1W-II102 supports long-distance extension up to 50m (12m standard), includes two terminal resistors. Large-capacity CPU units allow additional control power supply. CS1 CPU units offer up to 5120 I/O points, 250K steps of programming, 448 words of data memory (including extended data memory), and 4096 timers/counters. With large programming capacity, CS1 PLCs are suitable not only for large systems but also for value-added applications and data processing. Cycle time variation during data processing is reduced; instructions requiring longer execution time (e.g., table data processing and text string instructions) are processed over multiple cycles to maintain stable I/O response. Instruction execution speed and overall performance are improved through a parallel processing mode and an upgraded RISC integrated circuit. The system achieves industry-leading instruction execution performance. It supports conversion between floating-point decimals and strings (ASCII) for display on operator terminals (PT) and for converting ASCII data from measurement devices into floating-point decimal data for processing.
