6.6.8 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 applica-
tion 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 flexi-
ble, 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 dis-
played.
Parameter structure
The parameter Magnet Mode consists of two 8-bit unsig-
ned integer values: number of magnets and diagnostic
time.
The following values can be set for the number of mag-
nets:
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

6.6.9 PD In Mapping
This parameter allows the desired information to be map-
ped to the PDV (see „Process data (PD)“ on page 14).
Each PDV can be configured via the corresponding subin-
dex.
Each PDV is assigned an 8-bit unsigned integer as map-
ping 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)
