6.30 OB 230 to 237: Functions for Standard Function Blocks
The special function organization blocks OB 230 to OB 237 are
reserved for data handling functions and can only be called in the
standard function blocks FB 120 to FB 127.
Data handling blocks These standard function blocks, the data handling blocks known
simply as "handling blocks", control the data exchange via the page
area in the single and multiprocessor modes. They are used when data
or parameters and control information are transferred to or from the
communications processors (CPs).
Assignment aid You can use the table below to find out which handling blocks call the

Using the handling blocks The use of the handling blocks, that can be ordered as a software
product on diskette, is described in the manual "S5 135U
programmable controller, handling blocks for the R processor and
CPU 928/928B" /5/ in Chapter 13).
