5.7.4.2 Acyclic communication
For parameter access, an FB286 acyclic communication library must be
added to OB1.
The following describes how read and write blocks can be called.
Block FB286 is assigned to SINA_PARA.
Acyclic communication is established according to the PROFIdrive profile via
data block 47.
The FB286 acyclic communication block (SINA_PARA) provides the user with
an interface for easy reading and writing of any 16 parameters. The user
must specify the parameter numbers, an index and (for writing) a parameter
value. The job is processed independently after the start of the job.
The following steps show how to add an FB286 read and write block.
