4.1.2 How to Proceed if the Configuration is Modified at a Later Point
You know what the final configuration of a station will be, but you do not
have all the modules available, or you want to add some modules later.
1. Configure the station according to your final plan. In this way you specify
the module start addresses for all the I/O modules initially, even for those
that you have not added on yet.
2. Press <F6> (ENTER) to confirm the configuration.
3. Put the cursor in the input field for the slot that is not occupied yet.
4. Overwrite the address ID with “000”.
5. Press <F6> (ENTER) to reconfirm the configuration.
Overwriting the address ID with “000” maintains the address space for the
original module.
When you plug in the missing module later, you must reconfigure as follows:
1. Replace the “000” ID with the original address ID.
2. Press <F6> (ENTER) to confirm the configuration.
You want to add some I/O modules to a station that you have already config-
ured.
1. In the CONFIGURING screen, press <F4> (NEW STATION) to select the
number of the station that you want to expand.
COM ET 200 displays the configuration of the selected station. The “1st
available address” input field shows the address that will be assigned to the
additional module.
2. Enter the address ID of the additional module at the next available slot.
3. Press <F6> (ENTER) to confirm the configuration.
After you enter the new configuration, additional modules may have ad-
dresses that are out of sequence with the addresses of the originally config-
ured modules.
