Monitor version upgrade file for SX-Programmer : StandardMonitorUpdateV3143.exe

Main changes in the latest version: V3.1.4.3 (October 2025)

(1) Improvement of function

The following functions are added, and have been improved.

  • Added Model Transition Function to support migration from SPH200 to SPH2200-048RN.

  • Supports Model Change Function for SPH2200 and SPH3300. SPH2200 and SPH3300 can only be change Model Change within the same series.

    • NP1PM-048RN⇔NP1PM-048EN

    • NP1PU-048EN⇔NP1PU-096EN⇔NP1PU-128EN⇔NP1PU-256EN

  • Added new modules

    • Inverter︓FRN-GS1M (SX︓4W+4W/8W+8W/16W+16W/12W+4W/22W+29W)

    • Inverter︓FRN-GS1M (E-SX︓4W+4W/8W+8W/16W+16W)

    • Converter︓FRN-GS1P (SX︓4W+4W/8W+8W/16W+16W/12W+4W/22W+29W)

    • Converter︓FRN-GS1P (E-SX︓4W+4W/8W+8W/16W+16W)

  • The context menu configuration for the LD editor/ST editor has been partially modified.

  • Data modification and break point-related items have been moved to a sub menu.

  • Improve sampling trace and logging function.

    • The display of the sampled items has been modified to show the sample item name and the instance path separately.

    • When the graph operation tab is selected, tags have been modified to be displayed following the sample target (device name).

    • Display area of the sample target

  • Added the display of “Tag language Mode” on the status bar. Please change the setting in 【Tool】>【Option】>【Tag Display Mode】 and check it if your saved tag are not displayed.

  • SPF FW has been upgraded to V13.

  • The current consumption value of NP1Y32T09P1 (sink output 32 points) has been changed (52mA→45mA).

  • We have started support of Windows11 (Japanese, English O/S).

    • Target software︓MICREX-F PLC Programmer

(2) Problem correction

We have fixed the following problems

  • In a multi-CPU configuration, fixed a bug where the address assigned to a file declaration was being accessed from a multi-CPU address of another CPU, resulting in incorrect code generation due to the wrong address.

  • Fixed a bug in M/F Convert.

    • Fixed a bug where converting an MF program containing file instructions defined in SI format (16-bit) to SX format resulted in some addresses being replaced with DFL format (32-bit) file instructions.

    • Fixed a bug where step control devices that cannot be assigned to FB parameters were assigned during M/F conversion, causing code generation to fail.

  • Fixed a bug in Model Transition Function.

    • Fixed a bug where the Program/Data monitor could not monitored if Model Transition executed while Program/Data monitor screen is opened, and then transferred to PLC without editing.

    • Fixed a bug where the address specification of the FB instance was incorrect, and a data abort exception occurred when migrating from SPH2000-256E (NP1PM-256E) to SPH3300-256EN (NP1PU-256EN).

  • Fixed a bug in SX simulator.

    • Fixed a bug in the display of the model of SPH2200 (NP1PM-048RN, NP1PM-048EN).

    • Fixed a bug in SPH2200ʼs simulation mode where monitor writes to standard memory were not possible.

  • Fixed a bug in sampling trace and logging function.

    • Fixed a bug where if you register multiple trigger variables from among the
      sample targets in trigger mode and set some of them to trigger conditions, then delete all sample targets other than the variables set as trigger conditions, and then press the trigger setting button, an exception will occur, and the trigger settings screen cannot be opened.

    • Fixed a bug where the trigger point display position in the graph display of logging data was displayed in the “the number of samples before triggering” instead of “Negative direction of the number of samples”.

  • Fixed a bug in the backup function of the SX Control Utility, when the backup function of the SPH2000 SX Control Utility executed “Transfer→File to PLC”, the processing status of the PLC would become “Parameter error (0x22)”, and the SX Control Utility would be forced to terminate.

  • Fixed a bug where when a SPH3300 project is read from the PLC and transferred to the PLC after a program change, “FB instance configuration error” occurs, resulting in
    a fatal failure.

  • Fixed a bug where when performing a PLC in a SPH2200/3300 multi-CPU configuration, the address of the multi-CPU retain memory was converted to an incorrect address, resulting in an address mismatch.

  • Fixed a bug where when the number of program lines is larger than the number of vertical pixels in the window, the orange marker line (location display) on the far left
    of the left corner may not be visible when the project verify is performed, and the circuit comparison screen is opened.

Note)
  • The latest version supports Windows 10, 11.

  • The Chinese version was not upgraded. The latest Chinese version is V3.0.9.10.

Upgrading precautions

  1. 1.

    Make sure that NP4H-SWN/Standard is already installed on the computer prior to upgrading the software.

  2. 2.

    Do not begin the installation if the upgrade file is not exactly the same size as the file that was downloaded.
    If they are not the same size, throw all of them into the trash and download the upgrade file again.
