SEQLINK: Sequence linker

Block SEQLINK (FB475) helps interconnect PID_CTR blocks.

Functionality

Interconnection of the PID_CTR blocks occurs between the pins for block PID_CTR and a place on the SEQLINK block.

 

The sequence of the PID_CTR blocks must match the sequence of the places (free places may exist in the SEQLINK block).

 

Several SEQLINKs can be interconnected in series.
