modes
9.1 SIO
Mode
After start-up, the pressure switch is in SIO mode (standard I/O mode). In this mode, Pin 4
serves as a switching output.
The centre LED is constantly lit.
According
Chapter
13
Basic Settings
the behaviour of the ENS 3000 can be adjusted to
the corresponding application.
9.2 SDCI
mode
Via a connected IO-Link master the level switch can be switched to the SDCI mode
(Single-drop digital communication interface for small sensors and actuators), also known
as "IO-Link mode", by means of a wake-up signal. In this mode, Pin 4 serves as a
communication pin. The master is able to communicate with the pressure switch in order
to change parameters or to read out measured values.
The centre LED flashes.
In the SDCI mode a transmission of the process data is performed cyclically via the
communication pin 4 to the connected IO-Link master.
The ENS 3000 provides a process data width of 2 or 4 bytes, depending on the model
version, regardless if with or without additional temperature switch. 14 bits are used for
each actual measured value ("PDV" = "Process data value"). One decimal place is used
both for the fluid level and for the temperature.
