set the execution cycle of the function blocks and

schedule of execution.

5.6 Block Setting

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.
