Product Overview

The Siemens 6AG1350-1AH03-2AE0 is a SIPLUS S7-300 FM 350-1 high-speed counter module for applications that require dedicated counting and measurement functions within an S7-300 automation system. The module uses one high-speed counting channel and can process incremental encoder signals at frequencies of up to 500 kHz, making it suitable for applications where the PLC’s standard scan cycle would not be sufficient for direct pulse counting.

In a machine such as a conveyor, rotary positioning station, packaging line, or production counter, the FM 350-1 can receive pulse signals from an incremental encoder and perform the counting independently of the normal cyclic CPU processing. It can also be used for frequency, period, and speed measurement, so the same module can support more than simple piece counting.

The 6AG1350-1AH03-2AE0 belongs to the SIPLUS S7-300 range and is intended for industrial applications with extended ambient conditions. This version is based on the FM 350-1 and can also support clock-synchronized operation with a suitable interface module in an ET 200M configuration.

  • Can be integrated into established S7-300 control architectures without assigning high-speed counting entirely to the CPU program.

Working Principle

The FM 350-1 receives high-frequency pulse signals from an incremental encoder or other suitable pulse source and processes the counting operation directly in the function module. Instead of waiting for the S7-300 CPU to detect every transition during its normal scan cycle, the dedicated counter hardware handles the incoming pulses.

Depending on the machine application, the module can perform continuous counting, single counting, or periodic counting. The count process can be enabled or stopped through the user program using the software gate, or controlled through an external hardware signal when the application requires a faster physical trigger.

The same high-speed input processing can also be used for measurement functions. By evaluating pulse timing, the FM 350-1 can determine frequency, period, or speed. This is useful for rotary equipment where encoder pulses represent shaft movement or rotational speed.

For applications involving precise machine timing, the counting function can be coordinated with the broader S7-300 architecture. From the specified release associated with article number 6AG1350-1AH03-2AE0, the FM 350-1 can also operate in a clock-synchronized configuration with a suitable interface module in an ET 200M system.

Installation and Maintenance

  1. Confirm the S7-300 configuration — Check the rack arrangement and CPU configuration before installing the FM 350-1.
  2. Install the module correctly — Mount the counter module securely in the designated S7-300 position and ensure proper backplane contact.
  3. Connect the encoder — Wire the incremental encoder or pulse source according to the required signal configuration.
  4. Check signal quality — High-speed counting is sensitive to signal integrity, so inspect cable routing, shielding, grounding, and connector condition.
  5. Configure the counting function — Set the required counter mode, measurement function, gating behavior, and related parameters in the engineering configuration.
  6. Test the gate signal — Verify that the software or hardware gate starts and stops counting at the intended machine conditions.
  7. Compare actual counts with machine movement — During commissioning, check that encoder pulses correspond correctly to the expected mechanical movement.
  8. Monitor measurement values — Compare speed, frequency, or period values with the actual machine condition when using measurement functions.
  9. Inspect connections during maintenance — Check the module seating, encoder wiring, shielding, and signal terminals during scheduled control cabinet inspections.

Technical FAQs

What makes the FM 350-1 suitable for high-speed counting?

The FM 350-1 processes counter pulses through dedicated hardware rather than depending on the normal S7-300 CPU scan cycle. The module can handle counter signal frequencies of up to 500 kHz, depending on the encoder signal and application conditions.

Can the 6AG1350-1AH03-2AE0 measure speed as well as count pulses?

Yes. The FM 350-1 supports speed measurement in addition to continuous, single, and periodic counting. It can also perform frequency and period measurement, making it suitable for rotary machinery and encoder-based monitoring.

What is the purpose of the software gate and hardware gate?

The software gate allows the S7-300 user program to control when counting starts or stops. The hardware gate uses an external signal for this function, which can be useful when the counting window must be controlled directly by a machine event.

What should be considered when connecting an incremental encoder?

The encoder signal type, wiring, shielding, grounding, pulse frequency, and cable installation should all be checked. At high pulse frequencies, poor signal integrity can lead to incorrect counts or unstable measurement values, so the encoder interface and wiring arrangement should be verified carefully.
