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/OScanner. For example, a remote drop has:

Htwo 16±circuit discrete input boards (total of 32 input bits)

Hone 4±circuit analog input board (total of 64 input bits)

Hfour 16±circuit discrete output boards (total of 64 output bits)

Htwo 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 Reference Address assigned to the Remote I/O Scanner were 0001, Register Table contents would be:

R0001	=	16 inputs from 1st discrete input module
R0002	=	16 inputs from 2nd discrete input module
R0003 ± R0006 =		4 inputs from analog input module
R0007	=	16 outputs for 1st discrete output module
R0008	=	16 outputs for 2nd discrete output module
R0009	=	16 outputs for 3rd discrete output module
R0010	=	16 outputs for 4th discrete output module
R0011	± R0014 =	4 outputs for 1st analog output module
R0015	± R0018 =	4 outputs for 2nd analog output module

Individual discrete inputs and outputs can be read 16 bits at a time on the Register Table display by placing the cursor at the register that contains them. The bit values will appear at the top of the screen next to the word, EQUALS.

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.
