Start up

To save time during cyclic operation, certain functions and parameters are pre-assigned in the
work data block or transferred once in the initial start or restart routine.
In case of restart, the program continues at the point of interruption in the cycle. The WF 705
cannot restart, i.e. when used in the SIMATIC S7-400, an "automatic restart" is not
admissible, but an "automatic initial start".
The FC100:ANL_705 block needs the following parameters for initial starts and restarts:
• Data block number DBBG, containing the actual position values
• Number of steps/revolution for each encoder
• Module address
• Baud rate for each encoder
OB100
The DBBG data block provides the read-out actual position values of the appropriate WF 705
module. This data block is generated automatically by the FC100 block with 100 bytes unless
it exists already.
The user can generate the DBBG himself and increase its length if he wants to; the user can
then utilize the additional data words.
All S7 blocks needed for installation are on the standard diskette.
