DR 14 Selection process value 1, 2

The weighing module can communicate with an S7-1200 CPU in two ways: Via the I/O only
or by reading/writing complete data records. The I/O is faster in this case and exhibits a
higher performance because the data is made available to the S7-1200 or SIWAREX
automatically in each PLC cycle. Using two user-definable channels in the S7-I/O (process
value 1 and process value 2), the user can decide which scale values (see table) are to be
made available cyclically to the PLC in these two parameters.
