Selection
The master selects the traversing block to be started by entering the
block number
required block number into this control byte.
(AnwSatz)
The selection becomes effective, if:

Start byte
The start byte is compared with a bit mask "SMStart" (P86:x) pro-
(STB)
grammed in a traversing block.
This means that the program sequence can be influenced via the start
byte.

Control word
The master issues its commands to the slave using control word STW.

If neither a traversing block nor program is active.
The program or the traversing block has been completely executed.
The program or the traversing block was canceled by an external
signal or a fault.
P86:x (high byte) = 0:
The block is not influenced by the start byte.
P86:x (high byte) > 0:
The block can only be started if the bits, set in P86:x (high byte), are
also set in the start byte.
The program control can be additionally influenced via P80:x bit 6
and bit 7.
