The sensor will work with its default values as long as no changes have been made to it. With
parameters changed, the sensor will work with the changed data, which must be stored if they
are intended to be used after power off/on.
After completing the initialization procedure, the sensor sends a specific NMT command, the
boot-up message, which informs the system about the availability of the sensor. The MSA501
is now in the pre-operational mode. In this state, the sensor can be parameterized via SDO
commands in accordance with the requirements of the application. This applies to the
configuration parameters of the sensor unit as well as to the way it makes available to the
system its position values (asynchronous or synchronous data transmission).

General Information
In its standard version, the sensor has a bus terminator, which can be energized via an SDO
object (see chapter
5.6.2.25 5F09h: Bus terminator (not available with SP01 + SP03)
). The
SP01 +SP03 variant features an 8-pole DIP switch, which enables the adjustment of bus
terminator, node ID and baud rate. The sensor has 3 LEDs with yellow, green and red colors.
