The Series 90 TCP/IP Communications enabler supports reading and writing point data to the PACSystems, Series 90-70, and Series 90-30 controllers.

 Note: If you add a block to a programmable controller or resize domains, you must stop and restart the Series 90 TCP/IP Communications enabler in order for it to see the changes.

Data may be read from the following memory types:

Memory Type	Description	Memory Type	Description
%AI	Analog Input Table	%R	Register Memory
%AQ	Analog Output Table	%S	System Fault Table
%G	Genius Seamless	%SA	Special Contacts A
%I	Discrete Input Table	%SB	Special Contacts B
%L	Local Memory *	%SC	Special Contacts C
%M	Discrete Internal	%T	Discrete Temporary
%Q	Discrete Output Table	%W	Bulk Memory

* %L may only be used on Series 90-70 and PACSystems PLCs only

** %W may only be used on PACSystems RX3i and PACSystems RX7i

 

Data may be written to the following memory types:

Memory Type	Description	Memory Type	Description
%AI	Analog Input Table	%M	Discrete Internal
%AQ	Analog Output Table	%Q	Discrete Output Table
%G	Genius Seamless	%R	Register Table
%I	Discrete Input Table	%T	Discrete Temporary
%L	Local Memory *	%W	Bulk Memory

* %L may only be used on Series 90-70 and PACSystems PLCs only

** %W may only be used on PACSystems RX3i and PACSystems RX7i

Note: Proficy CIMPLICITY supports domain sizes of up to 65536 (64K) bytes only; however %W can be configured to a maximum size of 5242880 words (10M bytes). Therefore, the entire %W memory range cannot be accommodated within one domain.

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