BC3150 77Version: 2.1.0
Example
Var_1 AT %IB1000:INT; a 2-byteoutput variable has to be configured on the master side.
Var_2 AT %IB1002:DINT; a 4-byteoutput variable has to be configured on the master side.
The order of the variables on the master side must be adhered to. Address gaps are only permitted if they
are configured on the master side. Otherwise, addressing must be continuous from address 1000.
TWINCAT CONFIG
For the TwinCAT CONFIG, a configuration must be created via the System Manager. The System Manager
is used for specifying the type and number of variables and for linking the variables. The PROFIBUS data
may therefore be located anywhere in the permissible allocated process image.
Permissible process image:
INPUT %IB0 - %IB2047
OUTPUT %QB0 - %QB2047
