Output Characteristic

This parameter determines the output function of the BTL
with rising or falling characteristic curve. Access takes
place via subindex 0.
Value Output function
0x00 (FALSE) Falling (null point at the end of the rod)
0xFF (TRUE) Rising (null point at the electronic head)

6.6.10 Magnet Mode

The number of magnets can be fixed or flexible.
Setting a fixed number of magnets
When setting a fixed number of one or two magnets, the
BTL continually checks the number of detected magnets.
If this number does not match the presetting, the
application enters an error state: all process data values
are replaced with the error value.
Flexible magnet mode (FMM)
In Flexible Magnet Mode, the number of magnets is
flexible, allowing them to be changed during operation.
The time when the magnet is added or removed is critical,
since recording can then be re-adjusted and the contents
of the process data values moved if necessary. In this
case, a so-called diagnostic time is defined, which can be
configured in the BTL. During this time, an error value is
output for all process data variables and a corresponding
diagnosis (warning) is transferred via IO-Link. After the
diagnostic time lapses, the new application state is
displayed.
Parameter structure
The parameter Magnet Mode consists of two 8-bit
unsigned integer values: number of magnets and
diagnostic time.
The following values can be set for the number of
magnets:
0 = Flexible number of magnets (1 or 2)
1 = 1 magnet (fixed)
2 = 2 magnets (fixed)
The diagnostic time is set in 4-ms increments as follows:
1 = 4 ms
2 = 8 ms
...
255 = 1.02 s

Access to the parameter
Access to the parameter is possible as follows:
– Subindex 0: Byte 1 = diagnostic time
Byte 0 = FMM mode
– Subindex 1: Magnet Mode
– Subindex 2: Diagnostic time

6.6.11 PD In Mapping

This parameter allows the desired information to be
mapped to the PDV (see Process data (PD) on
page 14). Each PDV can be configured via the
corresponding subindex.
Each PDV is assigned an 8-bit unsigned integer as
mapping value. The following options can be set:
Value Designation
0x00 Position value, magnet 1
0x01 Position value, magnet 2
0x10 Velocity value, magnet 1
0x11 Velocity value, magnet 2
0x30 Current internal device temperature
0x40 Difference between magnet 1 and 2
0xFD Empty module (output as value 0)
