Series 90 TCP/IP Triplex Supported Memory Types
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: 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.
