Appendix A
Data Conversion
This section describes the data conversion method between different direct ac-
cess types and different PT models.
In the following explanation, the NT20, NT20S, NT30, NT30C, NT600S,
NT620S, NT620C, and NT625C are referred to as “conventional models” and
the NT21, NT31, NT31C, NT631, and NT631C (including models with “-V1,” “-V1
(System Ver. 2.1)” and “-V2 (System Ver.3.1)”) are referred to as “new models.”
Direct Access Types
Direct access type can be set at “PLC Vendor” of “PT Type (PT Configuration).”
Changing PLC vendor of existing screen data changes direct access type.
The direct access types that can be handled by the Support Tool (Ver. 4.
) are as
follows;
OMRON:
This is a direct access for OMRON PLCs
Memory Link:
This is a simulative direct access with which host and PT
execute sending or receiving of command via RS-232C/422A
communication.
Mitsubishi A:
This is a direct access for Mitsubishi A series PLC.
Mitsubishi FX:
This is a direct access for Mitsubishi FX series PLC.
Memory Link, Mitsubishi A and Mitsubishi FX can be set only with NT31, NT31C,
NT631 and NT631C with “-V1” and above.
Reference:
The direct access version that can be handled by the Support Tool is:
NT20S, NT600S: Ver. 5
Conventional models other than NT20, NT20S, NT600S:
Ver. 4
New models:
No direct access versions
Depending on the direct access types, exclusive system program may be
needed for the PT hardware.
For details of the system programs and system installer, refer to Appendix B
System Installer Operation.
Direct access version 4 screen data for the NT20S or NT600S, or direct access
version 3 or lower screen data from previous PT models can be used on Win-
dows by using version 4 or 5 of the Support Tool for Windows.
NT20M/NT600M screen data can be reused by converting it to NT20S/
NT600S screen data using the Support Tool for Windows. Refer to the Support
Tool for Windows Operation Manual (Cat. No. V028-E1-
).
To create screen data to be used for direct access (PLC vendor) other than
OMRON, Memory Link, Mitsubishi A and Mitsubishi FX, use system installer of
DOS version.
Conversion between different direct accesses (PLC vendor)
With the Support Tool (Ver. 4.
), data conversion between different direct ac-
cesses such as OMRON
→
Mitsubishi A or Mitsubishi FX
→
OMRON is possible.
