Repeat With 1-3 Low Clocks - TR-Electronic C 58 Serie Benutzerhandbuch

8.2.1.5 Repeat with 1-3 low clocks

With the programming "Repeat with 1-3 low clocks" with the second clock
sequence the stored position value is transferred again and serves for recognition of
transmission errors. According to the selection one up to max. three break clocks can
be inserted before the second clock sequence is starting.
A further clock sequence transfers a new updated data word. So a data word is
always repeated only once.
The data capacity at the transmission is adjusted with the parameter Number of
data bits. The data transmission begins with the most significant bit (MSB) and
contains the position bits (P).
Related to a certain number of clocks, the data can be shifted arbitrarily by the
parameter Number of data bits. The data can be transmitted right-justified or
left-justified, with leading "zeros" and without leading "zeros". Leading "zeros" are
produced if the parameter Number of data bits is programmed larger, as it would
be necessary from the total measuring length.
