Address of the Bus Terminals, which you have assigned to local PLCs (BCxx00)
If you don't know the address at which the Bus Terminals are located, which you have assigned to
the local PLC of your BC/BX:
Perform your hardware configuration in the System Manager.
Once you have entered all Bus Terminals and PLC variables, right-click on the BC/BX in the hard-
ware tree of the System Manager and select the menu item Export Variable Info...
A file is saved that you can insert in the PLC control under Import Project.
Under the global variables you now have the entry TwinCAT Import in which all variables are lo-
cated that you have assigned to the local PLC of your BC/BX.
6.6 Allocated flag area %MB..
6.6.1 Remanent and persistent data
There are special flags for remanent and persistent data in the higher memory area.
Remanent data
The remanent data is located in the flags area. The default setting is for 64remanent bytes, i.e. from %MB0
to %MB63. This region can be expanded to a maximum size of 4kbyte. It should be borne in mind that the
task time increases with the quantity of remanent data (approx. 0.5ms for 512bytes). The settings for the
remanent data can be made via the (TwinCAT) System Manager, or with the KS2000 configuration software
(Table 1, Register 15, default value 64 max. 4kbyte).
Persistent data
Persistent data is even more stable, and is retained even through a program download. The number of
persistent data must be greater than or equal to the number of remanent data! Like the remanent data, the
persistent data is located in the region allocated for flags (%MBxx). You can make the settings for the
persistent data using the KS2000 configuration software (Table 1, Register 18, default value 0, max.
4kbyte).
