GE Series 90 Addressing

The input / output tags addressed under the GE Series 90 Driver use the addressing system in the following table. An assist dialog is provided to help you create these addresses.

Preface the address with the register or bit type to be used. The limits on any actual addresses will depend on the configuration of the system and type of CPU used.

Address Format	Data Type
%I#	Discrete Inputs
%Q#	Discrete Outputs
%M#	Discrete Internals
%T#	Discrete Temporaries
%AI#	Analog Input
%AQ#	Analog Output
%G	Global Bits
%GY	Global Bytes1 %GY is addressed by Byte number and is 1 based. To read the first byte, the address would be %GY1 and would read the G bits 1-8. To read the sixth byte the address would be %GY6 and would read G bits 41-48. To go from bytes to start bit: start bit = (byte*8) – 7. To go from start bit to byte: byte = (start bit + 7)/8. This should always result in a whole number. Byte addressing is always on the byte boundary.
%R#	Registers
%W#	Words
%S#	Status Bits
%SA#	Status Bits
%SB#	Status Bits
%SC#	Status Bits

In this table, # represents the register or bit number, starting at one. Note that addresses configured as outputs can also be read by input tags.
