IO-Link interface (continued)
6.2.8 Ambient pressure
The sensor is equipped with ambient pressure monitoring
(index 0x2049 (8265)). The ambient pressure
(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 0x2049 (8265),
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 ambient pressure (see
Section Device commands on page 41).
A lower threshold (index 0x204A (8266) subindex 0x01 (1))
and an upper threshold (index 0x204A (8266)
subindex 0x02 (2)) can be defined for the ambient pressure
module. The sensor recognizes when a threshold is
exceeded and sets the Boolean variables for
undershooting the lower threshold (index 0x204B (8267)
subindex 0x01 (1)) or for exceeding the upper threshold
(index 0x204B (8267) 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 ambient
pressure can be switched off (index 0x204A (8266)
subindex 0x03 (3)).
