GE GFK-0787B user manual AnalogOutput Addressing, Example, 16 x 6 = 96 words required

7

Example:

An application has sixteen analog input groups (each of which is a 6±input group), including spares. The total number of analog inputs from these blocks would be:

16 x 6 = 96 words required.

If the Analog Input Table had a configured length of 1024, these inputs would be located in the table as shown below..

	Analog Input Table
%AI0001
	Voted Analog Inputs = 96
%AI0096
%AI0097	Available for single
	Genius analog inputs
%AI0736	or other use
%AI0737

Bus ªAº inputs = 96

%AI0832

%AI0833

Bus ªBº inputs = 96

%AI0928

%AI0929

Bus ªCº inputs = 96

%AI1024

As with discrete inputs, all of the analog inputs are available to the PLC application program.

AnalogOutput Addressing

Analog blocks with outputs can be used in a GMR system, but they do not operate in GMR mode.

They can be configured for Hot Standby CPU redundancy operation. In Hot Standby mode, an analog block accepts outputs from a bus controller at serial bus addresses 31. If that bus controller stops sending output data, the block accepts outputs from bus controller 30.

Remember that each PLC in the GMR system normally executes the same application program.
