6.9 Description of the IO-Link functionality (optional)
IO-Link is a point-to-point connection for the communication of the PBS Hygienic with an IO-Link master.
The PBS
Hygienic uses IO-Link technology which can be used in networks. SICK assumes that the integrity and the confi
-
dentiality of the data and rights which are affected by the use of this technology are ensured by the customer.
In any case, appropriate security measures, such as network separation, fire walls, virus protection or patch
management, are always to be taken by the customer, depending on the situation.
Physical layer
The PBS Hygienic supports the following features:
IO-Link specification:
Version 1.0
SIO mode:
Yes
Minimum cycle time:
2.3 ms
Rate:
COM2 (38.4 kBaud)
Process data length:
16 bit
Process data
The PBS Hygienic has 1 or 2 digital outputs. Both switching outputs are transmitted as process data over the
IO-Link.
In the 'SIO Mode' (standard I/O mode), i.e. no IO-Link operation, the switching output 1 will switch on pin 4 of the
M12 connector.
In the IO-Link communication mode, this pin is reserved exclusively for communication. Switching output 2 is
always switched in addition on pin 2 of the M12 connector.
With a Frametype 2.2, the 16-bit process data from the pressure switch are transmitted cyclically. Bit 0 is the
state of switching output 1 and bit 1 is the state of switching output 2. Where 1 and DC 24 V correspond to the
"closed" logic state of the respective output.
The remaining 14 bits contain the analogue value measured by the pressure switch. The start of the measuring
range (MBA) corresponds to a value of 1,000 and the end of the measuring range (MBE) corresponds to a value
of 9,000.
