l
In continuous measurement, it is possible for multiple latch events to occur within
one sercos
®
cycle. In this case, the counter (status IDN 409-411) is incremented and
only the last event is stored as a value in IDN 130-134!
l
If a measuring window is required, this must be defined
before
it is configured in IDN
509, otherwise an error message is issued.
l
There are some differences in the inputs between S300 and S400/S600
S300:
digital 1 -> IDN 130,131; digital 2 -> IDN 132,133
S400/S600:
digital 2 -> IDN 130,131; digital 1 -> IDN 132,133
l
The measurement sensor release (IDN 405 & 406 or P-IDN 3038) must take place
after the start of the command (IDN 170)!
l
When the command 170 is active, IDN 169+509 cannot be changed.
Examples:
a)
Input 1 only, but both edges
Phase 2:
P-IDN 3000 26
Digital input 1 as latch
Phase 2/3/4:IDN 179
0x03
both edges active
Phase 4:

The entered values are in IDN 130 + 131.
b)

Phase 2:
P-IDN 3000 26
Digital input 1 as latch
P-IDN 3001 26
Digital input 2 as latch
Phase 2/3/4:IDN 179

Information whether one or more events have already been recorded is found in:
l
IDN 179 Bits 0+1 for input 1 and Bit 7 (0x0080) for the extended difference.
The individual statuses are, of course, also available.
The recorded values are in:
l
IDN 130 + 131 for input 1 and in IDN 523 for the extended difference
