Operating instructions

8 IO-Link

The LFP uses IO-Link technology, which can be used in networks. SICK assumes that the integrity and
the confidentiality of the data and rights which are affected by the use of this technology are ensured
by the customer. In all cases, appropriate security measures, such as network separation, firewalls,
virus protection or patch management, must be taken by the customer on the basis of the situation in
question.
Physical layer
Process data width
The SICK LFP level sensor has two digital outputs. Both switching outputs are transferred as process
data via IO-Link. The Q2 switching output is also switched at pin 2 of the M12 plug. In SIO mode, the
C/Q1 switching output is switched at pin 4 of the M12 plug. In communication mode, this pin 4 is
reserved exclusively for communication.
With frame type 2.2, 16-bit information is transferred from the level sensor. Bit 0 indicates the switch-
ing status of switch Q1 and bit 1 the switching status of switch Q2. The remaining 14 bits indicate the
analog measured value of the level sensor in millimeters. The level is measured from the end of the
probe upwards in the direction of the process connection.
