IO-Link interface (continued)
6.2.7 Relative humidity
The sensor is equipped with humidity monitoring (index
0x2041 (8257)). The humidity (subindex 0x01 (1)) and the
minimum and maximum values since the last startup
(subindex 0x02 (2) and 0x03 (3)), since production
(subindex 0x04 (4) and 0x05 (5)) and since the last manual
reset (subindex 0x06 (6) and 0x07 (7)) are measured. The
values in index 0x2031 (8257), subindex 0x02 (2), 0x03 (3),
0x06 (6) and 0x07 (7) can be reset for all modules
simultaneously by means of a maintenance reset (see
Section System commands on page 41) or induvidually
for the humidity (see Section Device commands on page
41).
A lower threshold (index 0x2432 (8258) subindex 0x01 (1))
and an upper threshold (index 0x2042 (8258)
subindex 0x02 (2)) can be defined for the relative humidity
module. The sensor recognizes when a threshold is
exceeded and sets the Boolean variables for
undershooting the lower threshold (index (0x2043 (8259)
subindex 0x01 (1)) or for exceeding the upper threshold
(index 0x2043 (8259) subindex 0x02 (2)). These Boolean
variables are available in the status bits of the process data
(see Section Process data on page 39).
Additionally, the sensor can trigger IO-Link events if a
threshold is exceeded. The sending of events (see
Tab. 6-21 on page 40) for monitoring the humidity can
be switched off (index 0x2042 (8258) subindex 0x03 (3)).
