6.3 General Guidelines for Working with your Software
When designing your bus system, follow the procedure outlined below:
➣
Find out how many PLCs and field devices are required for your
application. Assign the L2 station addresses carefully since renaming
the L2 station addresses once you have configured them is time
consuming.
➣
All the configuration data should be stored in one file, i.e. whenever
possible, work "OFFLINE FD" with the PG hard disk.
Creating user files
As already mentioned, the CP 5430 TF/CP 5431 FMS has a receptacle for
a memory submodule. These submodules can be RAMs or EPROMs.
Depending on the particular submodule, 16 Kbytes to 64 Kbytes of memory
are available (for memory submodules refer to Section 4.2). The CP
expects to find the description of a link and the general parameters (user
data) in this memory submodule.
For the system-wide identification (S5 system) of submodules, there is a
system identification block (Edit -> CP Init: SYSID).
There are two ways of configuring (making entries/modifications) in the Init
-> Edit screen:
OFFLINE FD:
you create the blocks on disk and transfer the created
parameter set directly to a RAM submodule using the transfer function
Transfer -> CP Database Transfer -> FD -> CP. The transfer function is
only possible when the CP is in the STOP mode (Transfer -> Start CP/Stop
CP) or when the switch on the CP is set to STOP.
The transfer (blowing) of the parameter set to an EPROM submodule is
also possible with the transfer function Transfer -> CP Database Transfer ->
FD -> EPROM. An EPROM must be plugged into the EPROM interface.
ONLINE CP:
you create the blocks directly on the CP. Modifying and
transferring blocks is only permitted in the stop mode of the CP (Transfer ->
Start CP/Stop CP or switch on the CP set to STOP):
