System Role
The FM 350-2 counter module serves as a high-speed counting and measurement function module in the S7-300 system, designed for:
- High-speed counting with 8 independent 32-bit channels
- Frequency measurement up to 20 kHz
- Speed measurement for motion control applications
- Period duration measurement for process monitoring
- Dosing and batch counting applications
- Replacement for up to six FM 350-1 single-channel modules
Compatibility
Drop-in Replacements
- Predecessor: 6ES7350-2AH00-0AE0 (discontinued in 2011)
- Successor: 6ES7350-2AH01-0AE0 (current version)
- Compatibility: Successor is fully compatible with the original design
- Replacement: Direct drop-in replacement, but commissioning is required
- Programming software: STEP 7 V5.5 or higher
- Configuration: FM 350-2 Option Package required
Long-term Migration (S7-1500)
Recommended S7-1500 replacement: 6ES7550-1AA00-0AB0 (TM Count 2x24V)
Migration requirements:
- • Program must be ported to TIA Portal
- • Hardware module replaced with S7-1500 technology module
- • Configuration and programming completely different
- • Full re-engineering required, no plug-and-play migration
Applications
- Counting and measuring frequencies in industrial automation
- Speed measurement technology for motion control
- Precise period duration measurement for process control
- Dosing and batch counting applications
- Position monitoring with incremental encoders
- Replacement for older FM 350-2 modules

Frequently Asked Questions
Is 6ES7350-2AH01-0AE0 discontinued? What is its availability?
This module is still an active standard product. It is the successor to the discontinued 6ES7350-2AH00-0AE0 (discontinued in 2011). It remains fully available through Siemens and authorized distributors.
What is the difference between 6ES7350-2AH00-0AE0 and 6ES7350-2AH01-0AE0?
The 6ES7350-2AH01-0AE0 is the successor product and is fully compatible with the original design. While it is a drop-in replacement, commissioning is required as the module must be configured in STEP 7.
What is the maximum counting frequency this module can handle?
The module can handle a counting frequency of up to 20 kHz for each channel. For the FM 350-2, this allows for high-resolution measurements in various applications.
What types of sensors and encoders can be connected?
The module supports incremental encoders (asymmetric), 24V initiators, 24V directional sensors, and NAMUR sensors according to DIN 19 234.
Which programming software is supported? Do I need special licenses?
Supports STEP 7 V5.5 or higher. The FM 350-2 Option Package (comes with the module on CD-ROM) is required for configuration. In TIA Portal, the module is also supported for S7-300 systems.
Does the module support diagnostic alarms?
Yes, the module supports diagnostic alarms and diagnostic information readout. These are configurable for process and diagnostic alarms.
