SIWAREX blocks

For easier use, the WP231 weighing module provides the "WP231PR" (FB 231)
function block.
The block is integrated in the example project. However, they are also on the CD of
the "SIWAREX WP231 configuration package for SIMATIC S7-1200"
(Table 2-3), as well as in the "Ready_for_use_NAWI_WP231" projects (\6\).
4.2.1

"WP231PR" function block

The "WP231PR" FB is used for the communication of the S7-1200 CPU with the
SIWAREX WP231 weighing module via the backplane bus.
As of firmware V1.1 of the WP231 weighing module, apart from the communication
via the input and output address area, the data records can also read or written in
the WP231. Thus, the configuration of the weighing module is also possible without
the "SIWAREX WP231 configuration package for SIMATIC S7-1200"
