<Causes>

1. When the PLC model setting is changed, it is replaced with device "??".
2. PLC2 - 8 (Temperature Control/PLC2Way with the V7 series) are set as "not used".
3. Variable name cooperation is not accomplished with a PLC project file of Fuji Electric's MICREX-SX.

＊ If you are using the V-SFT-6, see here.

<Solutions>

1. When changing the PLC model, display the [Memory Conversion] dialog and change "??" to an existing memory address under [After Conversion Start Memory].
   

    

   Example: Change the PLC from Mitsubishi's QnU series CPU → Fuji Electric's MICREX-SX series CPU.
   
   

   (1) After the PLC model is changed, the "Execute device conversion?" message dialog will be displayed. Click [Yes].
   

    

   (2) Click the "??" memory after conversion that corresponds to the "M" memory before conversion.
   

    

   (3) Set WM0 in the [Memory Input] dialog, and click [OK].
   

   
   "M" memory is changed so that it will start from WM0.
   

    

2. Correct or delete all illegal memory addresses.
   Illegal memory addresses can be found by running an error check.
   

    

   Example: [Tool] → [Error Check]
   Move the cursor to the error item, and click the [Error Details] icon.
   The error details can be viewed.
   
   
   Click the [Jump to Error Item] icon  to jump to the error occurring position.
   Delete or modify the illegal memory address.
   

    

3. Link up with the PLC project file.
   List of PLC models which require linkup (IEC mode only *)
   
   • MICREX-SX (T-link)
   • MICREX-SX (OPCN-1)
   • MICREX-SX (SX bus)
   • MICREX-SX SPH/SPB/SPM/SPE/SPF series
   • MICREX-SX SPH/SPB/SPM/SPE/SPF CPU
   • MICREX-SX (Ethernet)
     * The current mode setting can be viewed by selecting [File] → [Project]→[Select Memory].

Example: MICREX-SX SPH/SPB/SPM/SPE/SPF CPU "IEC mode"

(1) Select [File] → [Project] → [Option], and check [? Cooperating work].

(2) Select the PLC project file (extension ".mwt").

(3) Check that the correct PLC project file is displayed for [Path], and click [OK].

* Note the following points for the project name and pathname. If not, the file will not be linked correctly.

• The following characters must not be used for the pathname.
  :, ., =, ;, <, >, [, ], /, ?, |, *, "
• The following characters must not be used for the project name.
  ¥, :, ., =, ;, <, >, [, ], /, ?, |, *, "
• The project name must not exceed 24 characters.
  (24 one-byte characters/12 two-byte characters, one-byte and
  two-byte characters can be used at the same time)
• The project pathname (from the drive name to the project name) must not exceed 171 characters.
