COM ET 200 Windows can read all program files generated with earlier
versions of COM ET 200.
COM ET 200 Windows V2.0 always saves the program files it reads in the
COM ET 200 Windows V2.0 format. COM ET 200 Windows V2.0 does not
generate program files in a format compatible with earlier COM ET 200
versions.
Precondition: All type files used to generate old COM ET 200 program files
must be in the COM ET 200 Windows directory "\KONVER4X". The
"\KONVER4X" directory is created during installation by the "type files of
V4.x" option.
Restriction: You can read slaves only up to a particular station number. The
station number depends on the addressing mode selected.
1 to 123 (linear addressing)
1 to 119 (P-page addressing)
1 to 107 (Q-page addressing)
COM ET 200 Windows cannot read binary files generated with earlier
versions of COM ET 200.
COM ET 200 Windows cannot read E(E)PROMs programmed for an
IM 308-B. COM ET 200 Windows reads and writes only memory cards. See
the appendix for order numbers.
If you have to read the program file of an E(E)PROM in an IM 308-B, you
can do so only with the COM ET 200 version used to generate the
E(E)PROM, or a higher version.
With the exception of diagnostics evaluation and Q-page addressing, you can
use the STEP 5 program just as it was written for a system parameterized
with an earlier version of COM ET 200.
On the IM 308-C, you must use the FB IM308C to evaluate diagnostics.
