; PROGRAM EXCERPT (relevant sections only)
; Test stop (forced checking procedure / Phase 1/2)
N14000 IDS=41 EVERY TESTST_PLC == BIT_0 DO TESTSTOP_1 = 1
N14100 IDS=42 EVERY TESTST_PLC == BIT_1 DO TESTSTOP_2 = 1
; Test stop (external stops / STOP A/C/D)
N14200 IDS=43 EVERY TESTST_PLC == BIT_2 DO TEST_STOPA = 1
N14300 IDS=44 EVERY TESTST_PLC == BIT_3 DO TEST_STOPC = 1
N14400 IDS=45 EVERY TESTST_PLC == BIT_4 DO TEST_STOPD = 1
; The markers TEST_STOPA, TEST_STOPC, TEST_STOPD are also
combined into the STOP A, STOP C, STOP D de-selection in a similar way to
the SPL program of the configuration examples.
The byte in the dual port RAM ($A_DBB[5] "TESTST_PLC") is assigned the
value for the actual test step via the FC 21 from the PLC program, i.e. the
transfer FC 21 is active for the test stops.
Version 2: Data transfer via the simulated NCK-I/Os
It is also possible to replace the wiring by a bitwise (bit-serial) data transfer via
the DB 10.
Limitations
MD 10350
MD 10360
To use the function for data transfer, MD 10350 and 10360 must be set
depending on how many bytes are to be used for data exchange.
If real inputs and outputs are present, they can be used regardless of SI. In this
case, MD 10366 $MN_HW_ASSIGN_DIG_FASTIN and MD 10368
$MN_HW_ASSIGN_DIG_FASTOUT must be set in accordance with the
hardware configuration.
Data exchange can only be used for bytes for which there are no real inputs
and outputs.
