Contrôle de mouvement: Safety status monitoring for elevators, cranes, conveyor systems

Energy Industry: Safety protection mechanisms for power generation and distribution systems

5. Replacement Part & Compatibilité
6. Official Replacement: 6ES7136-6BA01-0CA0 (enhanced version)

Added counting function (up to 500Hz, bidirectional counting)

Added standstill and overspeed monitoring functions

Configurable with TIA Portal V17 and higher

2. Compatibility Notes

Fully compatible with the original module in physical dimensions and mounting

Hardware configuration and safety program must be updated

Works with all standard ET200SP BaseUnits

6. Notes d'utilisation
7. Configuration Software Requirements

Original module: TIA Portal V12–V16 or STEP 7 V5.5 SP3 and higher

Replacement module: TIA Portal V17 and higher

2. Safety Programming

Safety programs must be developed using Siemens F-library function blocks

Safety programs require safety certification testing (par ex., TÜV Rheinland)

3. Wiring Rules

Safety input signals shall use twisted shielded cables, routed separately from non-safety signals

Shield grounded at one end to reduce electromagnetic interference

Siemens 6ES7136-6BA01-0CA0 vs 6ES7136-6BA00-0CA0: Différences fondamentales

1. Core Position & Replacement Relationship

6ES7136-6BA00-0CA0: 1st generation ET200SP fail-safe digital input module (F-DI 8x24VDC HF), abandonné, officially replaced by 6ES7136-6BA01-0CA0

6ES7136-6BA01-0CA0: 2nd generation upgraded version, currently in production, direct successor to 6ES7136-6BA00-0CA0

2. Key Comparison Table

3. Detailed Functional & Performance Differences

3.1 New Core Functions

Counting Function: Prise en charge 1 counter, up to 500Hz, bidirectional counting, suitable for safety counting applications (par ex., convoyeurs, packaging machines)

Standstill & Overspeed Monitoring: New safety-related motion monitoring, detects abnormal stop or overspeed to enhance safety protection

je&M Data Support: Adds I&M0–I&M3 data sets for improved traceability, lifecycle management, diagnostics, and maintenance

3.2 Software Configuration Notes

With TIA Portal V17+, select 6ES7136-6BA01-0CA0 directly to access all new functions

With older software (TIA V12–V16 or STEP 7 V5.5), the module can only be configured as 6ES7136-6BA00-0CA0 and new functions are unavailable

3.3 Physical & Electrical Compatibility

Identical physical size (15mm largeur) and mounting method

Same terminal assignment and electrical parameters (24VDC input, response time 0.4–20ms, etc.)

Supports same safety wiring (1oo1/1oo2), configurable as 8-channel SIL3/PL d or 4-channel SIL3/PL e

4. Remplacement & Upgrade Recommendations
5. Direct Replacement: Hardware can be swapped directly regardless of software, no configuration or wiring changes needed
6. New Projects: Prefer 6ES7136-6BA01-0CA0 to avoid discontinued parts and ensure long-term supply & support
7. Legacy System Upgrade

New functions require TIA Portal V17 or higher

Without software upgrade, direct replacement is possible but new functions are disabled; module behaves identical to legacy version

4. Risk Note: Re-test safety program after replacement to ensure proper operatio

As an upgraded version, 6ES7136-6BA01-0CA0 retains full safety performance and hardware compatibility while adding practical functions such as counting and standstill monitoring, plus improved software and diagnostics. The main constraint is a higher software version requirement, which must be considered when upgrading engineering software.
