A sampling time failure can be detected using function block SLD. The
counter status is interrogated at each SYNC interrupt (this is generated at
the end of every telegram cycle). The block can calculate and output the
difference to the old (previous) value.
The blocks reads the interrogated value of the counter and generates the
difference to the value which was saved in the old (previous) cycle. This
value is output at DT.
The minimum and maximum values of DT are kept for monitoring
purposes.
TAD
SLB hardware address (name of the SLB module), which can be
configured in HWConfig
DT
Delta time
Difference to the last SIMOLINK cycle duration
(default: 0)
DMX
Delta time, max.
Maximum value of DT
(default: 0)
DMN
Delta time, min.
Minimum value of DT
(default: 0)
SEQ
Sequence number
Number of the block in the SIMOLINK block sequence
This value provides information as to whether the block was correctly
initialized.
(default: 0)
YF
Error status of the block
YF=0
no error, YF > 0 refer to coded error output @SL
(default: 0)
QF
Group error bit
QF=0 no error, QF=1 for error (if YF
≠
0)
(default: 0)
