Loading the configuration in RUN
A modified configuration is loaded in RUN in the following two steps:
1.
Check that the current configuration can be loaded ("Station > Check CiR Capability").
2.
Download the configuration to the CPU ("PLC > Download to module ...").
Note
When the configuration is loaded to the CPU, the INTF LED goes and off again and the
EXTF LED comes on permanently. You cannot start added the real stations or modules
until the INTF LED has gone out. The EXTF LED then goes out again (see "Behavior of
the CPU after download of the configuration in RUN").
Back up your current configuration after each download of the station configuration from HW
Config (regardless of the CPU mode). This is the only way to ensure that you can continue
working with the backed up project in the event of an error (loss of data) without losing CiR
capability.
11.8.2.9
Undoing Previous Changes
Principle
You can undo any previous configuration changes that you downloaded to the CPU by
removing the slaves or modules you added at that time.
The following rules apply:
●
Remove slaves or modules from no more than 4 DP master systems.
●
Within a DP or PA master system, you must start at the highest PROFIBUS address of
the slaves you want to remove. You then continue with the slave with the next-highest
PROFIBUS address.
●
Within a modular DP slave of the type ET 200M / ET 200iSP, you must start with the
highest slot number of the modules you want to remove. In the HW Config view, this is
the module at the very bottom. STEP 7 offers the following support for this step: The
module that you can remove next is entered in the bottom part of the station window in
standard font; all other modules are shown in italics.
You then continue with the module with the next-highest slot number.
Procedure
1.
Select the object you want to remove.
2.
Select the "Delete" command in the shortcut menu or in the "Edit" menu.
