Diagnostics
A diagnostic alarm occurs if the same event triggers a further
process alarm during a process alarm processing.
Bit 5 ... 0: Reserved
Bit 6: Diagnostic alarm(0 = inhibited; 1 = enabled)
Bit 7: Reserved
Other values are not permissible!
0x00

Idle time
The dead time, also called tbs (time between sends), defines the
waiting time between two encoder values to be observed by the
module so that the encoder is able to process its value. This data
can be found in the data sheet for your encoder.

Baud rate
In "monitoring operation" operating mode, the baud rate is
irrelevant. Enter the baud rate here. This corresponds to the clock
frequency via which the encoder connected communicates.
Information on this can be found in the data sheet for your
encoder.

0x00 0x18: 2 MHz
0x00 0x20: 1.5 MHz
0x00 0x30: 1 MHz
0x00 0x60: 500 kHz
0x00 0xC0: 250 kHz

Standardisation
Depending on the encoder, further bits are transmitted in
addition to the encoder value. Scaling serves to determine how
many bits post-positioned to the encoder value will be removed
by shifting the encoder value to the right. The encoder value is
scaled by the module only after a Gray-binary conversion. More
information can be found in the data sheet for your encoder.
