3.2.2
Start up
To save time during cyclic operation, certain functions are carried out or transferred once in
the initial start routine.
The standard start up function block FB-ANL-705 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
OB20/21/22
The DBBG data block provides the actual position values of the appropriate WF 705 module.
This data block is generated automatically by function block FB 103 (EINRDB) with a length of
48 data words. During system start up, FB 103 is called in FB100/130/160 and checks if
DBBG already exists and if it doesn't, it is generated.
The user can generate this data block himself and increase its length if he wants to, the user
can then utilize the additional data words.
All the S5 blocks needed for installation are on the standard diskette.
