A traversing program is defined by a number of traversing blocks, the block numbers in
ascending order determining the direction of processing.
The WF 723 C is provided with a traversing block decoder which edits the traversing blocks in
such a way that necessary calculations and verifications during execution of the traversing
block can be avoided. This ensures short block-change and executing times.
Apart from basic conditions that have to be met for starting a stored program, the program
number, the read-in enable and the start signal must be available. The read-in enable activates
the traversing block decoder, the start signal enables the traversing block execution.
For a detailed description, see the chapter "control and acknowledgment
signals" in the description of functions.

For roll feed, there is no pre-decoding of traversing block, as they have to
be started one by one externally.
