This section deals with the aspects you should consider before starting
parameterization with COM ET 200 Windows.
Broadly speaking, there are two approaches to parameterization with
COM ET 200 Windows and to writing the application program:
You can begin by parameterizing the configuration with
COM ET 200 Windows and allow COM ET Windows to automatically
assign all station numbers and addresses in the STEP 5 application
program. Thereafter, you can have the program print the system
documentation and use this to set up your STEP 5 application program.
Alternatively,
Parameterization with COM ET 200 Windows and writing of the STEP 5
application program are parallel. If you opt for this alternative, you must
define the following before you start parameterization with
COM ET 200 Windows:
Before starting parameterization with COM ET 200 Windows, decide on the
following:
Table 2-3 COM ET 200 Windows and STEP 5 in parallel (IM 308-C)
Before starting parameterization with COM ET 200 Windows,
... which DP slave will have which station number.
... which addresses the DP slaves will use in the STEP 5 application
program.
The scope of the addresses determines:
... which mode of addressing you select (linear, P-page addressing or
Q-page addressing; plus FB IM308C).
The system requirements determine:
... which error-reporting mode you select: ... which error-reporting mode you select:
response monitoring for the DP slaves
QVZ (time-out) or PEU (powerfail in expansion unit) for the DP QVZ (ti t) PEU (
