set the execution cycle of the function blocks and
schedule of execution.

5.6.1 Link Object
A link object combines the data voluntarily sent by
the function block with the VCR. The transmitter
has 40 link objects. A single link object specifies one
combination. Each link object has the parameters
listed in Table 5.6. Parameters must be changed
together for each VCR because the modifications
made to each parameter may cause inconsistent
operation.
