EINZ
0 = Execute test unconditionally
1 = Execute test if it has not yet been
executed in the current test cycle
Execution of test if it has
not yet been executed in
the current cycle
I/BIBED
Distribute test to several
PLC cycles
I/BI
PAFE Message byte I/BY 00
H
= Test executed completely
41
H
= Faulty FB252 parameter
assignment
D0
H
= Test executing
0 = Execute complete test in one PLC
cycle
1 = Distribute test to several PLC
cycles
Note
If you select parameter EINZ = 0 and if you thus have the requested test executed in
one PLC cycle, the cycle time can rise so that the S5-95F goes to STOP with timeout.
Please observe the execution times of the test components (see Table 9-11).
