10 Isochronous Operation - Parameterizion
10.2 Device-specific parameters
10.2.5 Maximum master sign-of-life character failures
The maximum permissible number of master sign-of-life character failures can be
parameterized in parameter byte 24. Default: 1.
10.2.6 New features for GSD version SIEM81A8
Encoder Class 4 functionality
The "Encoder Class 4 functionality" parameter specifies whether scaling, preset
and counting direction applies to the values in XIST1.
Caution
For activated "Encoder Class 4 functionality", TI must be greater than or equal to
375 µs. Because a smallest Ti of 125 µs is specified in the GSD, a Ti smaller than
375 µs can be set in the HW Config and in HWCN.
While establishing a connection, a parameteriization error occurs for activated
"Encoder Class 4 functionality" and the MC-ENCODER does not enter the run
state.
Preset affects XIST1
The "Preset affects XIST1" parameter specifies whether or not for activated Class
4 functionality the preset value affects the XIST1.
Scaling function
The "Scaling function" parameter specifies whether or not for activated Class 4
functionality the scaling affects the XIST1.
Diagnostics via alarm channel
This parameter specifies the length of the diagnostic telegrams.
Compatibility mode V3.1
This parameter specifies whether the rotary transducer should operate compatible
to PI/PNO-ENCODER profile 3.1.
