PCs transmit I/O data through Masters, Slaves, and Remote Terminals according to allocated words.
Although words are not allocated to Masters and Slaves, they are allocated to all I/O Units and Remote Terminals in the
System. To enable proper word allocation, Unit numbers must be set for all Slaves and, in some Systems, word multipli-
ers must be set for Masters. A Slave or Remote Terminal must also be set as a terminator for each Master.
Section 3-1 provides block diagrams of various Remote I/O Units. Section 3-2 provides details and examples of Unit
connections, word settings, terminator settings, word multiplier registration, and the word allocations that result from
these. The basic setting procedure for the entire System is outlined in Section 3-3. Finally, Section 3-4 provides example
program sections used to start System operation when power is turned on to a Slave, rather than to the Master as it nor-
mally is.
