FC ST7ObjectTest
Validity
S7-300/400 CPU
Function
Calling FC ST7ObjectTest in programming error OB121 prevents a CPU STOP, if the CPU
receives data with an unknown destination object no.
FC ST7ObjectTest checks why OB121 was called, i.e. which block type is missing.
● If the missing block is a data block and this data block is an instance DB of a SINAUT
object, the CPU does not change to STOP.
● If no SINAUT instance DB is missing but rather another block (DB, FB, FC), you can
specify the reaction with the parameter "StopInOtherCases".
– CPU changes to STOP.
– CPU continues to run.
For more information on the programming error OB121 and background information relating
to the use of FC ST7ObjectTest, see section Programming error OB (Page 138).
