Realizes High-Speed Advanced Machine Control

Ultra-high-speed 1 ms controller

1 ms scan

  • Program scan time of 1ms is implemented by increased instruction processing speed.

  • Real number operation and high-precision positioning control have been put to practical use by dramatically improved floating-point operation speed.

For details on each instruction word's processing speed and tact cycle, see the User's Manual (FEH200).

1 ms I/O refreshing

  • 1024 points of I/O is refreshed in 1 ms.

  • Tact control assures a fixed I/O refresh interval. The I/O refresh cycle can be set to 1 ms, 2 ms, or up to 10 ms, which is suitable for processing requiring strict tact time.

  • The minimum tact times of SPH5000M, SPH300, and SPH2000/SPH3000 can be set to 0.25 ms, 0.5 ms and 1 ms,respectively.

Controller conforms to International Standard

Conforms to IEC 61131 international standard

  • Both the hardware and software conform to the IEC 61131 international standard for programmable controllers.

  • The programming language conforms to the IEC 61131-3 international standard.

Conforming to international standard

  • Conforms to the CE marking, UL standards and RoHS directive (conforming one after another) as well as IEC standard.

  • It also complies with the NK marine standard (Japan) and the LR (specifications of Lloyd's Register of Shipping, UK).

Conforming to international standard

Multi-CPU system applicable to up to 8 CPUs

Parallel processing with up to 8 CPUs (SPH300/SPH2000/SPH3000/SPH3000D/SPH5000M)

  • Alleviates the load for each CPU allowing high-speed processing of a large application program. For example, the load can be distributed for advanced processing and sequence control processing with additional CPUs. I/O refresh control is performed automatically even if parallel processing by multiple CPUs is performed.

Redundant System Brings System Safety and Reliability

1:1 warm-standby feature (SPH300/SPH2000)

  • This redundancy configuration enables continued operation without system downtime if a CPU fails. (Control may temporarily stop due to fault detection and CPU changeover.)

  • The same program is stored in CPUs for the active and backup systems, allowing constant data value equalization.

1:1 warm-standby feature (SPH300/SPH2000)

Highly reliable duplex system feature (SPH5000H)

  • Allows you to construct control systems that support redundant CPU, duplexed control network, duplexed I/O network, and loop network.
