GE GFK-0787B Initialization Data, + %R data needed for the application Spare, Global Data

6

The voted analog references start at %AI0001. The size of the voted analog input area is determined by the number of voted analog inputs including spares.

Physical input data from analog block groups is located at the end of the Analog Input Table, in the areas labelled A, B, and C in the preceding illustration. Each of these areas is equal in length to the number of voted inputs at the beginning of the table.

Unused portions of the Analog Input Table may be used for simplex inputs.

Example

The following illustration shows an example Analog Input memory configuration for a system with multiple GMR busses. There are a total of 30 input groups having 6 inputs each, and 19 input groups having 4 inputs each. So the total number of voted inputs is:

( 6inputs X 30 groups) + ( 4 inputs X 19 groups)=256 voted inputs

The simplex inputs could then begin at %AI0257.

Data from an analog block occupies either 4 or 6 input words, depending upon the number of analog input channels on the block.

%R Size: In addition to any other specific %R memory required for the application program, there must be %R memory available to the GMR software for bus controller data and communications data.

To configure the correct amount of %R memory for the application, use this worksheet:

_________ %R Initialization Data

+_________ %M Initialization Data (number of 16-bit words)

+_________ %R data needed for the application

+	_________	%R spare
+	320 words	Global Data

+_________ (Number of GMR Bus Controllers in CPU x 66 registers)*

=_________ Total Words of Register Data
