Chapter 7 Remote Drop I/O Data
Remote Drop Data in Register Memory
If Series Six or Series Five register memory is used for remote drop data, an amount is
required that is equal to the total number of bytes of input data PLUS output data. The
data is stored beginning at the assigned register reference. The sequence is: discrete
inputs, then analog inputs, then discrete outputs, and analog outputs last. Data
lengths are equal to the amounts of %I, %AI, %Q, and %AQ configured for the Remote
I/O Scanner. For example, a remote drop has:
required that is equal to the total number of bytes of input data PLUS output data. The
data is stored beginning at the assigned register reference. The sequence is: discrete
inputs, then analog inputs, then discrete outputs, and analog outputs last. Data
lengths are equal to the amounts of %I, %AI, %Q, and %AQ configured for the Remote
I/O Scanner. For example, a remote drop has:
H two 16–circuit discrete input boards (total of 32 input bits)
H one 4–circuit analog input board (total of 64 input bits)
H four 16–circuit discrete output boards (total of 64 output bits)
H two 4–circuit analog output boards (total of 32 output bits)
H one 4–circuit analog input board (total of 64 input bits)
H four 16–circuit discrete output boards (total of 64 output bits)
H two 4–circuit analog output boards (total of 32 output bits)
(This is the same set of boards used in the I/O Table example). If the beginning

Mixed Reference Table Displays
Customized Logicmaster displays can be created to show both discrete and analog
values at the same time, in a format that is meaningful when monitoring system
operations. The Logicmaster Software User’s Manual explains how to do this. In a Mixed
Reference Table, each line of the display can show either 64 input bits or ten registers.
To display discrete or register data properly on a mixed screen, the Remote I/O Scanner
should be configured for data lengths that match up with the discrete and register line
boundaries imposed by Logicmaster.
