More Information

Overview Manuals Input Conversion Output Path Processing Modes Diagnostic Events

Features:

  • Four analog inputs convert configured voltage or current signals into PLC data.
  • Four isolated analog outputs reconstruct controller words as field signals.
  • Operating modes coordinate conversion with conditional, comparator, or measurement sequences.
Two input channels are voltage-only, while the other pair accepts the documented current or voltage ranges.

Range modules and software settings must identify the same electrical configuration.

Diagnostic and end-of-cycle interrupts report different events to the CPU.

The Siemens 6ES7335-7HG01-0AB0 SIMATIC S7-300 SM 335 Analog I/O Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Matching field sources to the correct measuring path

  • Voltage pair: Two channels receive the configured voltage ranges.
  • Current or voltage pair: The remaining channels follow the selected current or voltage arrangement.
  • Range module: The mechanical setting identifies the permitted input circuit.
  • PLC value: Conversion places the measured result and status in the controller data area.

Turning controller words into isolated field signals

  • Output word: The CPU writes the commanded analog value through the backplane.
  • Range conversion: The configured channel range scales that word into voltage or current.
  • Field circuit: A two-wire connection carries the generated signal to the receiving device.
  • Reference path: Analog reference and sensor-supply wiring follow the documented common arrangement.

Selecting when conversion and comparison occur

  • Free cycle: Input and output processing repeats continuously.
  • Conditional mode: An assigned condition controls when the conversion sequence is handled.
  • Comparator mode: The module compares the configured values within its processing cycle.
  • Measuring only: The selected mode limits the task to acquisition without normal output processing.

Distinguishing channel conditions from cycle completion

  • Parameter error: A configuration mismatch prevents the intended channel range from operating.
  • Wire or range fault: The module reports supported field-side diagnostic conditions.
  • Diagnostic interrupt: The CPU receives a module diagnostic event through the rack.
  • End-of-cycle interrupt: A separate event indicates completion of the configured processing sequence.
Description
Siemens 6ES7335-7HG01-0AB0 is the SIMATIC S7-300 SM 335 analog input/output module that links four field measurements and four analog control signals with the PLC backplane. Its conversion circuits turn configured voltage or current values into controller data and reconstruct output words as field signals.

The four inputs of 6ES7335-7HG01-0AB0 are not interchangeable without configuration: two are voltage channels, while two accept the documented current or voltage ranges. Measuring-range modules and HW Config must describe the same electrical range so the converted value and diagnostic state represent the connected transmitter correctly.

Each output generated by 6ES7335-7HG01-0AB0 follows its configured range through a two-wire field connection. The output circuits are isolated from the backplane, while their analog reference and the integrated 10 V sensor supply share the documented field-side arrangement.

Processing modes change how 6ES7335-7HG01-0AB0 updates data: free-cycle operation converts continuously, while conditional, comparator, and measuring-only modes coordinate conversion with the configured control sequence. Diagnostic and end-of-cycle interrupts then inform the CPU about module conditions or completed processing.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does Siemens 6ES7335-7HG01-0AB0 return an implausible analog value?
Compare the Siemens 6ES7335-7HG01-0AB0 measuring-range module position, HW Config range, channel wiring, and transmitter signal type.
Can every input on 6ES7335-7HG01-0AB0 accept either current or voltage?
No. The 6ES7335-7HG01-0AB0 has two voltage inputs and two channels that accept the documented current or voltage configurations.
What must be saved before exchanging 6ES7335-7HG01-0AB0?
Keep the 6ES7335-7HG01-0AB0 hardware parameters, channel ranges, processing mode, interrupt settings, and front-connector assignments.
How should an output problem on Siemens 6ES7335-7HG01-0AB0 be isolated?
For Siemens 6ES7335-7HG01-0AB0, verify the PLC output word, configured range, 24 V supply, analog reference, and two-wire load connection.
Why can 6ES7335-7HG01-0AB0 generate an interrupt when no channel is failed?
The 6ES7335-7HG01-0AB0 can issue an end-of-cycle interrupt separately from a diagnostic interrupt, depending on the selected processing mode.
Is 6ES7335-7HG02-0AB0 automatically interchangeable with 6ES7335-7HG01-0AB0?
No. Siemens identifies a successor, but 6ES7335-7HG01-0AB0 replacement still requires verification of hardware, parameters, wiring, and program behavior.
