Familiar user interface

The user interface and ladder programming support SPB programming equivalent to a FLEX-PC Windows-compatible PC loader.
Support for full-keyboard operation is also handy for on-site debugging and maintenance. With a whopping 202 different instruction words, the possibilities for your programs are limited only by your imagination.

Compatible with the international standard IEC 61131-3 (JIS B 3503)

Program representations support the LD language, which is most standard. The ST and FBD programming languages are also supported. Programming in units of POU in which the structured design method is applicable can be performed.

Full-fledged programming environment

• Programming allows all addresses to be specified, and allows off-line editing (edit and continue).

• Support the Structured design and the parting that used to the FB (Function block).

• Function block (FB) callers are expressed as block-format FBD, enabling you to identify in and out parameters at a glance (SX mode).
  
  
• Debugging features
  Powerful debugging facilities are provided, including step execution, conditional monitoring, sampling traces, and fault analysis.
  
  
• Conditional monitor function
  This is a function to read and display data collected by PLC when conditions are met.
  This function enables high-precision analysis.

Leverage your program assets

In SX mode, you can copy and paste your programs from our FLEX-PC series PLCs. On-line help describes alternate methods for circuits and instructions that cannot be pasted in. In N mode, use your program and comment files as-is.

Resume feature

When the software is started, the previous edit/monitor position is automatically displayed.
When you go on-line, monitoring starts at the position you were monitoring last time. When you are off-line, the system transitions to edit mode displaying the point you were editing last time.

Failure diagnostic function

Failure diagnosis is easy because you can analyze failure information while checking the configuration information.

Link with spreadsheet program

Directly copy comments edited/created in a spreadsheet program (Excel) into your program.

USB interface

The connection method using the full-speed USB (Universal Serial Bus) 1.1 has been added as a loader connection method.
Communication with the SPH300 (NP1PS-□□R), SPH300EX and SPH2000 can be performed at high speed using a commercial USB cable.

Data access to the user ROM

Projects can be downloaded from/uploaded to the user ROM card (compact flash card) supplied with SPH300 (NP1PS-□□R), SPH300EX or SPH2000. Also, data can be written into/read from the user ROM card.

Support also of SPB and FLEX-PC programming

Standard supports three types of programming (SPH, SPB, and FLEX-PC).
However, there is no SPH program compatibility between Standard and Expert (D300win).
Program editing can be performed by selecting SPB (N mode/SX mode), SPH, or FLEX-PC during file selection after activation.

Password function

By setting an access authentication password for on-line functions, operation of the PLC can be limited to three levels, i.e., level 1, level 2, and level 3.
