Supported SNP and SNPX Memory Types

NOTE: If you add a block to the programmable controller or resize domains, you must stop and restart the SNP Communications Enabler in order for it to see the changes.

Data may be read from the following memory types:

%AI

Analog Inputs

%R

Registers

%AQ

Analog Outputs

%S

Discretes

%G

Genius Global Data

%SA

Discretes

%I

Discrete Inputs

%SB

Discretes

%M

Discrete Internals

%SC

Discretes

%Q

Discrete Outputs

%T

Discrete Temporaries

Data may be written to the following memory types:

%AI

Analog Inputs

%M

Discrete Internals

%AQ

Analog Outputs

%Q

Discrete Outputs

%G

Genius Global Data

%R

Registers

%I

Discrete Inputs

%T

Discrete Temporaries

Caution: Do not write data into the system registers (%S, %SA, %SB, and % SC). Doing so may interfere with the normal operation of the programmable controller.
