Discrete I/O Tables: Example

In this very simple example, there are:

Ha model 788 CPU (with 352 physical I/O).

HOne output group of four discrete 16-circuit blocks. The application program will use logical outputs at addresses %Q0001 to %Q0016.

h This requires just 16 output references, because the references used by all four blocks in the group are the same. The references that these blocks will be configured to respond to are assigned to the 16 bits at the end of the output table. Since the example CPU is a model 788, the 16 references at the end are:

%Q1009 to %Q1024

hThe corresponding 16 bits in the Input Table are also reserved for GMR fault detection disabling. The reserved input references are:

%I1009 to %I1024

HOne input group of three discrete 32-circuit blocks. The application program will use voted inputs at addresses %I0001 to %I0032.

h The beginning Input Table reference for the data is equal to:

I/O Table length ± reserved inputs ± (3 X input data length for one group) +1

For the example, this is:

1024 ± 16 ± (3 x 32) +1 = 913 = %I0913

hIn the output table, the corresponding area (%Q0913 to %Q1008) is reserved.

HOne non-voted discrete 16-circuit block.

If configured as a combination block, it occupies references %I0033 to %I0048 in the Input Table and %Q0033 to %Q0048 in the Output Table. Notice, as shown in the illustration, that these references begin after the last voted input reference and that output references %Q0017 to %Q0032 are not used.

The illustration shows where these inputs and outputs would be located in the I/O tables. Shaded portions represent unused I/O table memory.

Voted inputs = 32

non-voted I/O =16

bus A inputs = 32

bus B inputs = 32

bus C inputs = 32

Reserved inputs = 16
