4.11.13.7.17.2 DPI/IP protocol (BALLUFF) / EP protocol (MTS)
Requirements for a successful upload of the transducer rod parameters to the module:
1. Selection of the communication protocol (DPI/IP or EP). See section . 4.11.13.7.11 "Channel configuration"
2. Transducer rod must support the respective protocol.
3. If the transducer rod does not support the selected protocol, the module will detect this after a timeout of
approx. 300 ms and will treat the rod as a "normal" transducer rod.
After the module is started or after a transducer rod is connected, the parameter upload should be complete within
200 to 400 ms.
A communication error causes the data upload to cancel. A new upload attempt can be initiated by the user by
deactivating and reactivating the communication protocol using asynchronous access.
All rod parameters can be read to the controller using asynchronous access. The read parameters "rod length"
and "ultrasonic speed" are
NOT
automatically uploaded to the module.
It is left up to the application whether the upload values for rod length 1 and rod length 2 or for ultrasonic speed 1
and ultrasonic speed 2 are uploaded.
Information:
Keep in mind that no position measurements can be performed on a rod while parameters are being
uploaded. The module freezes all existing position/speed data for all magnets on the rod while the
parameters are uploading. Parameters should therefore only be uploaded with the machine stopped,
and this should be ensured by the application.
4.11.13.7.18 Minimum cycle time
The minimum cycle time defines how far the bus cycle can be reduced without communication errors occurring.
It should be noted that very fast cycles decrease the idle time available for handling monitoring, diagnostics and
acyclic commands.
Minimum cycle time
250 µs
