Explanations
OUTPUT_VALUE You specify the number of pulses with this value.
Value range: 1 to 4294967295
D
(2
32
-1)
If the setting is outside the value range, the ERR_OUT_VAL feedback bit is set and the last
valid number of pulses is used.
SLOT You specify the load value with this value.
Value range:
• Period duration in μs: 10 to 85000000
D
• On delay in μs: 0 to 85000000
D
• Duty cycle:
– Output format "1/100": 0 to 100
D
– Output format "1/1000": 0 to 1000
D
– Output format "1/10000": 0 to 10000
D
– Output format "S7 analog output": 0 ... 27648
D
You specify whether to apply a change once or cyclically with MODE_SLOT.
Invalid values trigger setting of feedback bit ERR_LD (when MODE_SLOT = 0) or
ERR_SLOT_VAL (when MODE_SLOT = 1).
MODE_SLOT You specify whether you want to apply a change in SLOT once or cyclically with this bit.
0 means: As soon as you write the respective value in the corresponding output byte, the value
from SLOT is applied once and kept until the next change. A change via SLOT takes effect at
the next output sequence. After a restart of the module, the value is overwritten with the value
set in the hardware configuration.
1 means: When you write the respective value in the corresponding output byte, the current
value from SLOT in each case is applied cyclically. A change via SLOT takes effect at the next
output sequence.
