If station B is a PS416 controller, the number of segments is
adjustable. The standard setting in the application module is
for 512 segments. If you wish to change the number of
available segments on the memory card, refer to the section
entitled “Function block SetMCFileLength” of the manual
“S40 Language Elements for PS4-150/-200/-300 and
PS416” (AWB2700-1306-GB).
If you change the number of available segments, you must
alter the range limit for function block input
“tra_flash_segment” in the variables declaration for the
function block:
section “Default parameters” from page 15.
