Bosch BUEP19
6.4 Bosch BUEP19
The Bosch BUEP19 protocol allows you:
– random read and write access to all PLC data
– bit-by-bit access to all byte, word and double-word oriented data ty-
pes
– byte-by-byte access to all data words in a data block.
The size of the address area depends on the controller being used.
This protocol supports a connection to the following CPU modules:
– ZE300
– ZE301
– R300
– R301
– R600
6.4.1 Data Types
Direct access is possible to the following data types.
The size of the individual data areas depends on the controller of the
controller's CPU.
When the system writes to individual bits and individual bytes of a flag
word, a read-access is performed first. Then, the entire data structure
can be accessed for a write operation. During this type of access, you
must therefore take care that the operating device and the controller do
not modify individual bits in a byte (or individual bytes in a data word).
