The PLC device memory address for a part is garbled as "??" or is "blank".
<Causes>
- When the PLC model setting is changed, it is replaced with device "??".
- PLC2 - 8 are set as "not used" (delete).
- Variable name cooperation is not accomplished with a PLC project file of Fuji Electric's MICREX-SX.
<Solutions>
- When changing the PLC model, display the [Device Conversion] dialog and change "??" to an existing device memory address under [After Change Start Device].
 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 "??" device memory after conversion that corresponds to
 the "M"device memory before conversion.
 
 (3) Set WM0 in the [Device Input] dialog, and click [OK].
 
 "M" device memory is changed so that it will start from WM0.
 
- Correct or delete all illegal device memory addresses.
 Illegal device memory addresses can be found by running an error check.
 Example: [Tool] → [Error Check]
 
 Click the [Jump to Error Item] icon to jump to the error occurring position.
 Delete or modify the illegal device memory address.
- 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 [MICREX-SX] → [Select Device].
(1) Select [MICREX-SX] → [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.
