Fb_Sact Function Block Restrictions - Siemens SIMATIC PCS 7 System Manual

FB_SACT function block restrictions

This block is used for updating the storage location overview screen "FB_STOR.pdl". The
maximum volume of data that can be sent using raw data via the BSEND function block may
be reached with this block (16230 bytes). You must therefore make sure that the user-defined
columns can be displayed on the "FB_STOR.pdl" overview screen. Because 25 rows (storage
locations) are displayed on the screen, each column needs 25 times the memory space in the
AS function block "FB_SACT". The following table shows the memory space required for each
of the various formats that can be shown on the screen. The sum of the memory space required
by the maximum of ten columns must not exceed 16230 bytes.
