Identity Number (21 bits)
The Manufacturer Code represents the manufacturer identification SICK AG (value
885 decimal).
The Identity Number corresponds to the J1939 serial number of the encoder.
The following fields of the device name are predefined as factory defaults:
•
Manufacturer Code: 885 (SICK AG)
•
Identity Number: J1939 serial number of the sensor
•
Industry Group: 0
•
Vehicle System: 0
•
Function: 142 (Rotation Sensor)
The remaining ranges can be modified by the user via the configuration protocol (
5.4
Process data (transmit PGNs)
The device supports 3 different parameter groups (TxPGNs):
•
TxPGN1 65504 (FFE0h): Position (4 bytes), speed (2 bytes), diagnostics (2 bytes)
•
TxPGN2 65505 (FFE1h): Position (4 bytes), temperature (2 bytes), diagnostics
(2 bytes)
•
TxPGN3 65506 (FFE2h): Speed (4 bytes), temperature (2 bytes), diagnostics
(2 bytes)
Activation/deactivation of sending, the cycle time, and the priority of messages can be
set using configuration messages. By default, TxPGNs 65504 (FFE0) are activated with
a cycle time of 10 ms.
