Remote I/O Examples Example #1 – SLC 500 Controller without Block Transfer
This example demonstrates discreet control of an SMC Dialog Plus™
controller from an SLC 500 logic controller. Additionally, the SLC controller
reads the Current Phase A from the SMC Dialog Plus controller via the
analog feedback word. Many of the selections shown are example-specific.
Some changes by the user may be necessary to apply the concepts of this
example to a specific application.

Note: It is critical that during the system design phase that each device
on the Remote I/O link is allocated a unique segment of the
SLC's I/O image table. This is accomplished by coordination of
the device's rack address, rack size and starting group address.
