Programmable Controller PLC
Features
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/SPH2200/SPH3300 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).

Multi-CPU system applicable to up to 8 CPUs
Parallel processing with up to 8 CPUs
(SPH300/SPH2000/SPH3000/SPH3000D/SPH2200/SPH3300/SPH5000M/SPH5000EC)
(SPH300/SPH2000/SPH3000/SPH3000D/SPH2200/SPH3300/SPH5000M/SPH5000EC)
-
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.

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.

Ultra-high speed E-SX bus
Comparison of functions and performances between the E-SX bus and the SX bus






Synchronization control of E-SX bus
Synchronization in the bus
Data output timing is synchronized in the E-SX bus.

Synchronization between buses
Data output timing is synchronized between channels of the E-SX bus.

Connection function of the E-SX bus
Loopback function
Communication is continued by the signal repeater function even when a wire is broken.

Signal bypass function
Even when a power of some devices is not turned on, the communication is continued by the auxiliary power unit.
