Moving; Encoder And Dynamic Error (Watchdog); Even Parity, Even Error Parity - TR-Electronic C 58 Serie Benutzerhandbuch

5.4.4 UP
The special bit is set when Going up is set and it is deleted when Going down is
set.

5.4.5 Moving

The special bit is set while either Going up or Going down is set.

5.4.6 Encoder and dynamic error (watchdog)

As long as the position data can be measured and transmitted without errors, the
signal bit Encoder error is deleted and the signal bit Dynamic error supplies a
square-wave frequency of 250 Hz. In the case of an error, the Encoder error is set
and the Dynamic error stays at any level.
If it is possible the dynamic error instead of the encoder error should be use, since the
dynamic error is very likely to also detect faulty program execution in the device.
The following errors are reported:
-
-
-
-
If the error is eliminated, the error can be deleted about the input "Preset" or if the
supply voltage is switched-off and then switched-on again.

5.4.7 Even parity, Even error parity

The parity bit serves as control bit for the error detection during SSI data
transmissions.
The parity represents the checksum of the bits in the SSI data word. If the SSI data
word contains an odd number of "1", the special bit Even Parity = "1" and supplements
the checksum to even parity. Therefore the Parity or Error Parity special bit must
always be defined at the last digit. It is calculated from all previous bits. About that,
only one single Parity special bit is possible.
By selection of the inverted Parity the Odd Parity or the Odd Error Parity can
be deduced.
If no encoder error is present, the error parity corresponds exactly to the normal parity.
In the case of an error, it is inverted. Its purpose is to make additional transmitting of
the encoder error unnecessary.
