Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 | S7-200 SMART SR30 / SR40 / SR60 CPUs

SECTION 01

Product Introduction

Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 are SIMATIC S7-200 SMART AC/DC/Relay CPUs that combine an AC-powered controller, 24 V DC digital inputs and relay outputs. The order numbers select thirty, forty or sixty integrated digital points while retaining the same modular SR architecture.

As the point count rises, Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 increase program and data memory from 18 KB / 16 KB to 24 KB / 20 KB and 30 KB / 24 KB. Each CPU can add six expansion modules and one signal board, so the local I/O size and the right-side module plan can be considered together.

For plant communication, Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 provide one 10/100 Mbit/s PROFINET interface and one RS485 interface. Ethernet supports programming, HMI and configured controller communication, while the isolated serial port supports system protocols or freeport operation from 1,200 to 115,200 bit/s.

Product Functions

Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 scale one SR control architecture across three onboard I/O densities.

SR30 machine cell›SR40 mid-range panel›SR60 high-density base
01

SR30 machine cell

Eighteen inputs and twelve relay outputs suit a thirty-point cabinet while preserving the full SR expansion path.

02

SR40 mid-range panel

Twenty-four inputs and sixteen relay outputs increase fixed wiring capacity without changing the engineering family.

03

SR60 high-density base

Thirty-six inputs and twenty-four relay outputs reduce the number of external digital modules needed in a larger local station.

SECTION 04

Communication and Connectivity

Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 connect local field wiring, Ethernet devices, serial equipment and right-side modules through separate resources.

01

Ethernet device path

One PROFINET port carries programming, HMI and supported controller or I-Device traffic without consuming the RS485 channel.

02

Independent serial link

The RS485 interface retains its own address, baud rate and protocol settings for a separate field or freeport network.

03

Backplane power budget

Up to six expansion modules share the 1,400 mA 5 V bus allowance, so their current values are totaled before the cabinet is wired.

SECTION 05

Frequently Asked Questions

Why can a project for Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 show address conflicts after changing CPU size?

Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 use different onboard point counts, so downstream I/O addresses and terminal references must be reconciled after a hardware change. Select the exact installed CPU and rebuild the address plan before downloading.

How should expansion power be checked for Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1?

For Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1, add the 5 V bus demand of every expansion module and keep the sum within 1,400 mA. Calculate field and sensor current separately because the 300 mA sensor output is not the expansion-bus supply.

Why can relay LEDs switch while loads remain off on Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1?

The relay contacts on Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 do not create load voltage. Verify the external load source, the correct common, the return path and group-current limits before replacing the CPU.

Can Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 run PROFINET and RS485 communication together?

Yes. Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 provide separate Ethernet and RS485 hardware, but each network still requires its own addresses, protocol settings and cable rules.

What should be reviewed before replacing Siemens 6ES7288-1SR30-0AA1 with 6ES7288-1SR40-0AA1 or 6ES7288-1SR60-0AA1?

A change among Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 affects enclosure width, onboard I/O, memory and terminal allocation. Confirm spare DIN-rail space, program hardware selection and every field-wire destination rather than treating the larger CPU as a pin-compatible swap.

Why does an HMI reach one of Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1 but not exchange values?

Network reachability alone does not confirm a valid application connection to Siemens 6ES7288-1SR30-0AA1 / 6ES7288-1SR40-0AA1 / 6ES7288-1SR60-0AA1. Check that the HMI targets the exact CPU, uses matching IP parameters and reads addresses that exist in the downloaded program.
