5 Operation

The following section provides information required when using
software to operate the EtherCAT Sensor. Communicating with the
EtherCAT sensor requires knowledge of EtherCAT standards and
operation.

5.1 Sensor Enviroment

NOTICE

Damage to the outer jacketing of the transducer cable could en-
able moisture or water to enter an otherwise sealed transducer.

Ensure the cable jacketing is in good condition to prevent
transducer damage.

NOTE

Transducers may react to exceptionally strong and changing elec-
tromagnetic fields, such as those produced by magnetic reson-
ance imaging (MRI) machines.

To ensure proper operation, the IP64 rating of the transducer must
match or exceed the transducer’s environment.

5.2 Sample Rate

The power-on default sample rate is 975 Hz. The “Sample Rate”
field 

Object 0x7010: Control Codes

 [

 26] controls the current

sample rate. The following table lists the rounded and exact
sample rates.
