Device Access Locks

With this standard parameter, it is possible to activate or
deactivate certain functions of the IO-Link device. With
BTL6-U101-..., there is the option to lock the function of
the parameter manager. To do so, bit 1 of the 2-byte value
must be set to "1" (locked). In order to unlock the
parameter manager, bit 1 is set to "0".
Bit 0 Lock parameter access
(not supported)
Bit 1 Lock parameter management
(supported)
Bit 2 Lock local parameterization
(not supported)
Bit 3 Lock local user interface
(not supported)
Bit 4 to 15 Reserved

6.6.2 Profile Characteristic
This parameter indicates which profile is supported by
the IO-Link device.
Transducer BTL6-U101-... supports the smart sensor
profile with the following function classes:
– Subindex 1 (Profile Identifier -> DeviceProfileID):
0×0001 (Smart Sensor Profile)
– Subindex 2 (Profile Identifier -> FunctionClassID):
0×8000 (Device Identification Objects)
– Subindex 3 (Profile Identifier -> FunctionClassID):
0×8002 (ProcessDataVariable)
6.6.3 PD Input Descriptor
This parameter describes the composition of the process
data variables used.
Each process data variable can be reached via the
corresponding subindex (subindex 1 for PDV1, subindex 2
for PDV2, etc.).
Each subindex consists of 3 bytes:
– 1st octet: 0x03, data type = signed integer
– 2nd octet: 0x20, data size = 32 bits
– 3rd octet: 0x00, bit offset = 0 (or a multiple of 32)
The complete process data description for all PDVs can be
read out via subindex 0. All blocks of 3 are lined up,
beginning with the description of the highest value PDV.

Application Specific Tag

The Application Specific Tag makes it possible to assign
the IO-Link device an arbitrary, max. 32-byte string. This
can only be used for application-specific identification and
applied in the parameter manager. The entire object is
accessed via subindex 0.
6.6.5

Null point offset

Like the process data value, this parameter is a signed
32-bit decimal value. The programmed value must be
within the null and end point in the valid measuring range.
The value is deducted from the actual output value as a
simple offset and therefore shifts the position of the
magnet to an arbitrary point in the measuring range where
the value 0 is output. Access takes place via subindex 0.
The offset value can also be set and deleted via System
Commands (see System Command on page 15).
6.6.6

Event Configuration

All application events can be switched off via the
parameter Event Configuration so that they do not have to
be output by the transducer.
To activate or deactivate an event or the Invalid Bit
function, the corresponding object can be addressed
directly via the subindex and filled with a Boolean value
(True = 0xFF, False = 0x00) (see Tab. 6-7).
Subindex Event
Subindex 1 Invalid Bit Function
Subindex 2 Position Error
Subindex 3 Position Warning End Point
Subindex 4 Position Warning Nullpoint
Subindex 5 Magnet Change
Tab. 6-7: Event Configuration
The events can also be configured using access via
subindex 0. The last 5 bits are assigned to the sequence
named in Tab. 6-7 and can simply be masked out.
