Product Overview

Siemens 6ES7193-6BP00-0DA1 Replacement for ET 200SP: Seamless Transition & Legacy System Upgrade

The Siemens 6ES7193-6BP00-0DA1 is a BU15-P16+A0+2D BaseUnit designed for the ET 200SP distributed I/O system — one of Siemens’ most widely deployed field-level automation platforms. As legacy installations built around earlier ET 200S, S7-300, or first-generation ET 200SP configurations approach end-of-life, the 6ES7193-6BP00-0DA1 BaseUnit serves as the critical mechanical and electrical foundation for a smooth, low-disruption migration. This page provides procurement engineers, system integrators, and maintenance teams with the technical context needed to evaluate, source, and deploy this BaseUnit as a direct replacement or upgrade component within an existing SIMATIC automation architecture.

The ET 200SP platform is engineered for modular, rail-mounted distributed I/O deployment in control cabinets and field enclosures. The 6ES7193-6BP00-0DA1 BaseUnit supports push-in terminal technology, enabling tool-free wiring and significantly reducing installation time during both initial commissioning and field replacement. Its 16-channel I/O capacity, combined with integrated potential distribution (A0+2D configuration), makes it directly compatible with a broad range of digital and analog I/O modules from the ET 200SP family — including the 6ES7131-6BF01-0AA0 8DI module and the 6ES7132-6BF01-0AA0 8DO module — without requiring additional terminal blocks or wiring adapters.

For sites migrating from ET 200S installations, the transition to ET 200SP via the 6ES7193-6BP00-0DA1 BaseUnit requires attention to DIN rail footprint differences. ET 200SP modules are narrower than their ET 200S predecessors, which typically results in a net reduction in control cabinet width — a meaningful advantage when retrofitting existing enclosures with limited horizontal space. The push-in terminal design also eliminates the screw-terminal torque requirements that were standard on ET 200S BaseUnits, reducing the risk of wiring errors during field replacement.

From a communications perspective, the 6ES7193-6BP00-0DA1 integrates into ET 200SP stations managed by an IM 155-6 PN interface module (such as the 6ES7155-6AU01-0BN0), which handles PROFINET communication back to the S7-1500 or S7-1200 CPU. Sites currently running PROFIBUS DP with legacy S7-300 CPUs and ET 200S remote I/O can migrate to PROFINET by replacing the DP interface module with a PN-capable IM 155-6 and re-engineering the GSD/GSDML device configuration in TIA Portal V16 or later. The hardware configuration process in TIA Portal supports direct import of ET 200SP station topologies, and the 6ES7193-6BP00-0DA1 BaseUnit is fully catalogued within the TIA Portal hardware library, eliminating manual device definition.

Power supply compatibility is a key consideration during migration. The ET 200SP system requires a 24 V DC supply, and the BU15-P16+A0+2D configuration of the 6ES7193-6BP00-0DA1 supports both load group and potential group configurations. When replacing BaseUnits in an existing ET 200SP station, engineers should verify the current potential group assignments to ensure that the replacement BaseUnit maintains the correct supply voltage segmentation — particularly in mixed-signal stations where 24 V DC digital outputs and analog signal circuits share the same rack. The 6ES7193-6BP00-0BA0 light-colored BaseUnit variant is commonly used alongside the 6ES7193-6BP00-0DA1 in the same station to separate potential groups, and both variants are mechanically interchangeable on the same DIN rail segment.

For installations involving SIMATIC S7-1500 CPUs with centralized I/O expansion, the ET 200SP station anchored by the 6ES7193-6BP00-0DA1 BaseUnit can be configured as a PROFINET IO device with deterministic cycle times as low as 250 µs, supporting high-speed process control applications. The BaseUnit’s color-coded terminal design (dark BaseUnit = new potential group) provides a visual installation guide that reduces wiring errors during rack assembly and field maintenance — a critical advantage in high-density control cabinets where technician access is limited.

Spare parts management is a common driver for sourcing the 6ES7193-6BP00-0DA1. As ET 200SP stations age, BaseUnit terminal wear from repeated wiring cycles can degrade contact reliability. Replacing the BaseUnit — rather than the entire I/O module — is a cost-effective maintenance strategy that preserves the installed I/O module investment. The 6ES7193-6BP00-0DA1 is backward compatible with all ET 200SP I/O modules released since the platform’s introduction, including the 6ES7134-6GD01-0BA1 analog input module and the 6ES7138-6CG01-0BA1 F-DQ 4x24VDC/2A PP HF safety output module, ensuring that existing module inventory remains fully usable after BaseUnit replacement.

Seamless Upgrade Solutions

A complete ET 200SP station migration typically involves more than a single BaseUnit. When upgrading from a legacy ET 200S or PROFIBUS-based architecture, the following components are commonly sourced alongside the 6ES7193-6BP00-0DA1 to ensure a fully functional, tested station before installation:

The IM 155-6 PN ST interface module (6ES7155-6AU01-0BN0) is the PROFINET head module that anchors the ET 200SP station and manages all downstream I/O communication. It replaces the DP coupler used in ET 200S stations and is required for any PROFINET-based migration. Alongside it, the BU-COVER (6ES7193-6PA00-0AA0) end cover is required to terminate the BaseUnit bus connector on the rightmost module position — a mandatory component that is frequently overlooked during initial procurement.

For digital I/O expansion within the same station, the 6ES7131-6BF01-0AA0 (8DI 24VDC ST) and 6ES7132-6BF01-0AA0 (8DO 24VDC/0.5A ST) modules mount directly onto the 6ES7193-6BP00-0DA1 BaseUnit without additional adapters. Analog signal acquisition is handled by the 6ES7134-6GD01-0BA1 (4AI U/I 2-wire ST) analog input module, which is commonly used in process control applications migrating from S7-300 analog I/O cards.

For stations requiring functional safety, the 6ES7138-6CG01-0BA1 F-DQ 4x24VDC/2A PP HF safety output module integrates into the same ET 200SP rack and is certified for use in SIL 3 / PLe applications — enabling safety and standard I/O to coexist in a single compact station. Power supply for the ET 200SP station is typically provided by a SITOP PSU100S 24V/5A (6EP1333-2BA20) or equivalent 24 V DC regulated supply, which should be verified for adequate current capacity when adding modules to an existing station.

Programming and commissioning of the migrated station requires a SIMATIC S7 USB programming cable or direct Ethernet connection to the TIA Portal engineering station. For sites without an existing TIA Portal license, the STEP 7 Safety Advanced package is required if F-modules are included in the station configuration. Signal isolation between field devices and the ET 200SP I/O is recommended for long cable runs or electrically noisy environments, using DIN-rail-mounted signal isolators compatible with 24 V DC I/O levels.

Retrofit Guidance FAQ

Q: Can the 6ES7193-6BP00-0DA1 replace an existing ET 200SP BaseUnit without rewiring?
A: Yes. Within the ET 200SP family, BaseUnits of the same color and terminal configuration are mechanically and electrically interchangeable. The push-in terminals accept the same wire gauges (0.2–1.5 mm² solid or stranded) as the original unit. No rewiring is required if the replacement BaseUnit matches the original’s potential group color (dark = new potential group).

Q: Is the 6ES7193-6BP00-0DA1 compatible with PROFIBUS DP systems?
A: The BaseUnit itself is protocol-agnostic — it is the interface module (IM) that determines the communication protocol. To use this BaseUnit in a PROFIBUS environment, pair it with a PROFIBUS-capable IM 155-6 DP module. For PROFINET, use the IM 155-6 PN ST or HF variant.

Q: What TIA Portal version is required for hardware configuration?
A: TIA Portal V13 SP1 or later supports the ET 200SP platform. For F-module integration, TIA Portal V14 or later with the STEP 7 Safety Advanced option package is required. The 6ES7193-6BP00-0DA1 is catalogued in all current TIA Portal hardware libraries.

Q: How much DIN rail space does the 6ES7193-6BP00-0DA1 require?
A: The BaseUnit has a width of 15 mm on the DIN rail. A full ET 200SP station width depends on the number and type of I/O modules installed. ET 200SP stations are significantly more compact than equivalent ET 200S configurations, typically reducing total station width by 30–40%.

Q: Can this BaseUnit be used in a mixed station with both standard and safety modules?
A: Yes. Standard (dark) and safety-rated BaseUnits can coexist in the same ET 200SP station. Safety modules require F-capable BaseUnits (identified by the F designation in the order number), while standard modules use the 6ES7193-6BP00-0DA1. The TIA Portal hardware configuration enforces correct module-to-BaseUnit pairing during compilation.

Q: What is the maximum number of BaseUnits per ET 200SP station?
A: A single ET 200SP station supports up to 64 I/O modules (and thus up to 64 BaseUnits), subject to the current consumption limits of the interface module and the 24 V DC supply. Always verify total current draw against the IM module’s maximum backplane bus current rating before finalizing station design.
