Converting STEP 7-Micro/DOS Files to STEP 7-Micro/WIN Files
Import Guidelines and Limitations
When you import a Micro/DOS .VPU program file, a copy of the following Micro/DOS files are
converted to the Micro/WIN format after you save them:
Program files
V memory and data (not applicable for the CPU 210 and PDS 210)
Synonyms and descriptors
Status chart that has the same name as the project
The following actions occur when you import a Micro/DOS program into a Micro/WIN project:
Constants that were defined in V memory are maintained. (not applicable for the
CPU 210 and PDS 210)
Micro/DOS synonyms are converted to Micro/WIN symbols, but truncated, if necessary,
to fit the 23-character limit. The synonym descriptors, which can be up to 144 characters,
are truncated to the 79-character limit for symbol comments in Micro/WIN.
Micro/DOS network comments (up to 16 lines of 60 characters) are preserved in the STL
and LAD editors.
A Micro/DOS status chart that has the same name as the Micro/DOS program is
converted to a Micro/WIN status chart. For example, if you have a program named
TEST.VPU that has status charts TEST.CH2 and TEST2.CH2, the status chart named
TEST is imported, but not the status chart named TEST2.
The network address, password, privilege level, output table, and retentive ranges are
set based upon the Micro/DOS files. You can find these parameters with the menu
command CPU
Saving the Converted Program
To add the imported program to the same directory as your other current STEP 7-Micro/WIN
projects, follow these steps:
1. Select the menu command Project
your current STEP 7-Micro/WIN directory.
2. In the File Name box, type the name you want to assign to the imported program files,
using the .PRJ extension.
3. Click the "OK" button.
Note
Once saved or modified, the program imported into STEP 7-Micro/WIN cannot be exported
back into the STEP 7-Micro/DOS format. The original Micro/DOS files, however, are not
changed. You can still use the original files within STEP 7-Micro/DOS.
