Siemens 6ES7153-1AA03-0XB0 | SIMATIC ET 200M IM 153-1 DP ST — PROFIBUS DP Interface / Max 8 S7-300 Modules / 24VDC / 350mA / 5ms Bridging / 3W

The Interface That Connects ET 200M to PROFIBUS

The IM 153-1 DP ST is the PROFIBUS DP interface module at the head of every ET 200M distributed I/O station. Without it, the signal modules in the ET 200M rack have no network connection — the IM 153-1 is what makes the station visible to the PROFIBUS DP master, manages the cyclic I/O data exchange, and distributes the communication data to the installed S7-300 signal modules on the station's internal backplane.

The IM 153-1 DP ST is the standard variant — not the High Feature (IM 153-2 HF). It supports up to 8 S7-300 signal modules per station, standard PROFIBUS DP cyclic exchange, and basic station diagnostics. There is no redundancy, no isochronous mode, and no DP V1 acyclic services. For installations where the station needs only reliable cyclic I/O exchange without timing synchronisation or intelligent device management, the IM 153-1 DP ST provides everything required at lower cost and complexity than the HF variant.

The 5ms stored energy time ensures the module continues operating through brief supply dips — transient disturbances on the 24V DC cabinet supply that are common near frequency inverters and motor starting equipment. Short interruptions that would otherwise cause the station to drop off the PROFIBUS bus and require a restart are bridged without data loss.

Key Specifications

Application Scenarios

Distributed I/O cabinet at machine section: An ET 200M rack installed in a local sub-panel near the machine section, connected to the main S7-300 or S7-400 CPU over PROFIBUS DP. The IM 153-1 DP ST manages communication from the main PROFIBUS cable; field wiring for sensors and actuators in that section connects locally.

Replacement in existing PROFIBUS-based systems: Many S7-300, S7-400, and PCS 7 systems built around PROFIBUS DP with ET 200M stations continue in production. When the IM 153-1 fails, replacing it with the same IM 153-1 DP ST restores the station without any configuration change — the PROFIBUS address is set via rotary switch to match the original, and the signal module bank below it is undisturbed.

Process industry field panels: ET 200M with IM 153-1 DP ST is standard in process industry field junction boxes where analogue transmitters and discrete field devices connect to a PROFIBUS DP trunk. Up to 8 signal modules per station handles a reasonable field device count from a single distribution point.

Cost-effective standard I/O without redundancy: Where station availability during controller failover is managed at the PROFIBUS master level (S7-400H with dual DP masters), standard IM 153-1 DP ST stations are often sufficient. The redundancy architecture sits at the master side; the station simply reconnects to the active master.

FAQ

Q1: How does the IM 153-1 DP ST differ from the IM 153-2 HF?

The IM 153-1 DP ST supports up to 8 S7-300 modules with standard cyclic PROFIBUS DP exchange only — no redundancy, no isochronous mode, no DP V1 acyclic services, no timestamping. The IM 153-2 HF supports up to 12 modules, station redundancy (dual-DP redundant connection), isochronous mode, and DP V1 acyclic parameter access. Specify IM 153-1 DP ST for standard installations; IM 153-2 HF for stations requiring redundancy or isochronous operation.

Q2: How is the PROFIBUS station address set?

Via a rotary address selector on the module's front face. Set the address to match the value assigned to this slave in the DP master's STEP 7 hardware configuration. A mismatch between the physical selector and the configured address activates the BF (Bus Fault) LED and excludes the station from the PROFIBUS bus cycle until corrected.

Q3: What happens to ET 200M outputs if the PROFIBUS connection is lost?

The module's PROFIBUS watchdog expires when no valid DP telegram is received within the configured timeout. On timeout, the ET 200M station enters a safe state — output modules typically de-energise all outputs or hold last values depending on how module parameters were set in STEP 7 hardware configuration. The response is configurable per station during commissioning.

Q4: Can S7-300 signal modules from any revision be used with the IM 153-1 DP ST?

Yes. The IM 153-1 DP ST is compatible with the full range of S7-300 SM (signal modules), FM (function modules), and CP (communication processors) that fit in the ET 200M rack, up to the 8-module maximum. Confirm compatibility for any specialised function or communication modules with Siemens product documentation.

Q5: Where is the 6ES7153-1AA03-0XB0 sourced?

Through the Siemens ET 200M aftermarket — Siemens service channels, industrial automation spare parts dealers, and tested surplus suppliers. The IM 153-1 AA03-0XB0 is a widely deployed ET 200M interface module; aftermarket availability is generally reliable. Confirm the full part number including the AA03-0XB0 revision from the installed module's label — adjacent IM 153-1 revisions (AA00, AA01, AA02) are functionally compatible but the AA03 is the latest revision in this series.
