10 BYTE Device ID – encoder type
11..14 UINT32 Physical Resolution Span (number of steps per
rev. resp. span) which the encoder supports --
(PRS)
[8,192] rotary enc.
[4,096] linear enc.
15..16 UINT16 Physical Number of Revolutions (number of revo-
lutions resp. span) which the encoder supports
[8,192] rotary enc.
[4,096] linear enc.
9.4.2 Diagnostic Header
The header information shows the length of the diagnostic data (including the header byte) in
hex format. Octets 7 to 16 = user diagnostic data.
9.4.3 Alarms
Alarms are triggered when a serious error occurs in the encoder system. The message is de-
leted when the master has read the complete diagnostic data. The error display, too, will then
no longer be present.
Each correct detail within the supported alarms/additional alarms also triggers the alarm-specific
Commissioning Diagnostics Alarm Bit.
