Expanded local I/O
Eighteen inputs and twelve 2 A relay outputs provide a larger onboard signal set than CPU SR20 while keeping the controller self-contained.
Technical Summary
Controller profile6ES7288-1SR30-0AA1 is the CPU SR30 AC/DC/relay controller for SIMATIC S7-200 SMART systems. The 110 mm housing carries eighteen integrated digital inputs and twelve relay outputs for machine and panel applications.
The CPU is engineered in STEP 7 Micro/WIN SMART and provides one Industrial Ethernet interface, one RS485 interface, optional microSDHC support and PROFINET connectivity for up to eight IO devices.

Features
Integrated capabilitiesNetwork and serial access
The built-in Ethernet and RS485 interfaces support two distinct integration paths without consuming an expansion position.
Deterministic service data
The exact -0AA1 suffix, firmware version and project archive remain part of the replaceable-unit identity.
Maintenance media
Optional microSDHC support and a seven-day clock backup help preserve a controlled service and recovery process.
Compatibility
System fitConfirm that the approved STEP 7 Micro/WIN SMART release supports the installed CPU firmware.
Retain device names, IP configuration and the design limit of eight connectable IO devices.
Document protocol, baud rate, station address, termination and any converter used on the serial path.
Match the eighteen-input/twelve-output terminal map and verify each relay load before energization.
Replacement
Controlled exchangeBefore removal
- Capture the complete 6ES7288-1SR30-0AA1 nameplate, firmware version, project revision and communication settings.
- Export the running STEP 7 Micro/WIN SMART project and record expansion modules, PROFINET devices and serial nodes.
- Isolate the mains supply and all external voltages routed through the relay contacts.
Before restart
- Confirm the 110 mm housing and the exact eighteen-input/twelve-output terminal assignment before reconnection.
- Load only the validated project and verify clock, Ethernet, RS485, expansion I/O and every onboard point.
- Treat a move to CPU SR20 or CPU SR40 as an engineering change rather than a catalog-number substitution.
FAQ
Customer checksQ01What evidence is needed to identify 6ES7288-1SR30-0AA1 correctly?
Use the complete nameplate, firmware display or service record, project archive and photographs of the installed terminal wiring and expansion modules.
Q02Can 6ES7288-1SR30-0AA1 be exchanged for an older SR30 suffix automatically?
No. The same SR30 family name does not remove firmware, hardware-execution and project compatibility checks; validate the full article number before exchange.
Q03When should 6ES7288-1SR30-0AA1 be selected instead of SR20 or SR40?
Select by the validated local I/O count, memory requirement, enclosure width and project architecture—not by physical similarity or family name alone.
Q04What communication records should be preserved for 6ES7288-1SR30-0AA1?
Keep the Ethernet IP and device name, PROFINET topology, RS485 protocol settings, station addresses and cable-termination record.
Q05How should 6ES7288-1SR30-0AA1 be commissioned after replacement?
Restore the approved project, verify the firmware boundary, test all eighteen inputs and twelve relay outputs, then prove every networked device and affected safety function.
