More Information

Overview Manuals Channel Pairing Input Timing Diagnostic Paths Safety Evaluation

Features:

  • Sixteen physical inputs can be assigned individually as single-channel points or combined into eight two-channel evaluations.
  • Selectable input filtering lets the project balance response time against the documented cable-screening boundary.
  • The safety architecture supports SIL 2 in single-channel use and SIL 3 in a valid two-channel arrangement.
The a.x and b.x naming scheme keeps each possible two-channel pair visible during configuration instead of treating all sixteen terminals as unrelated points.

A 0.8 ms filter setting requires shielded conductors for both digital inputs and sensor supply, so timing selection directly affects field wiring.

Input LEDs provide local state feedback while the PROFIsafe configuration carries the evaluated safety information to the S7-1200 controller.

The Siemens 6ES7226-6BA32-0XB0 SIMATIC S7-1200 SM 1226 F-DI Module may be available for purchase and support from Apter Power.

Assigning a.x and b.x inputs

  • Single-Channel Choice: An a.x or b.x point can be evaluated independently as a 1oo1 input.
  • Two-Channel Choice: The matching a.x/b.x pair can be combined into one 1oo2 safety input.
  • Per-Pair Setting: Each pair on 6ES7226-6BA32-0XB0 is assigned separately in the module configuration.
  • Capacity Result: The selected pattern determines whether the module presents sixteen single points or eight paired evaluations.

Filter choice and field wiring

  • Delay Selection: Five parameterized filter times let the input response be matched to the signal behavior.
  • Fastest Setting: Selecting 0.8 ms introduces the documented shielding requirement.
  • Sensor Supply: At the fastest filter, the sensor-supply cable must be shielded together with the digital-input cable.
  • Run Length: The field connection remains within the specified 200 m cable boundary.

Separating local state from safety evaluation

  • Input Indication: Front LEDs show the current state of the individual digital inputs.
  • Pair Context: The project configuration identifies whether a lit point belongs to a 1oo1 channel or one side of a 1oo2 pair.
  • Module Context: Diagnostic handling remains associated with the SM 1226 F-DI module inside the S7-1200 station.
  • PROFIsafe Route: Safety-related input information is transferred through the configured PROFIsafe path.

How channel structure changes the limit

  • One-Channel Limit: A single-channel 6ES7226-6BA32-0XB0 evaluation is specified to Category 3, PL d and SIL 2.
  • Two-Channel Limit: A valid paired evaluation can reach Category 3 or 4, PL e and SIL 3.
  • Configuration Dependency: The higher classification depends on using the two-channel structure rather than merely installing the module.
  • Input Assignment: Safety planning must therefore match the a.x/b.x pairing to the intended evaluation architecture.
Description
Within the SIMATIC S7-1200 platform, Siemens 6ES7226-6BA32-0XB0 is the SM 1226 F-DI fail-safe digital input module. It acquires 24 V DC field states for a PROFIsafe safety configuration and keeps those inputs within a dedicated 70 mm module width.

Channel organization is selectable on 6ES7226-6BA32-0XB0: each a.x and b.x pair can remain two separate 1oo1 inputs or become one two-channel 1oo2 evaluation. This produces either sixteen single-channel points or eight paired safety inputs without changing the physical module.

Input timing on 6ES7226-6BA32-0XB0 is set from five filter values. The shortest 0.8 ms choice changes the wiring boundary because the digital-input and sensor-supply cables must then be shielded, while the documented maximum run remains 200 m.

Status LEDs on 6ES7226-6BA32-0XB0 expose the input states during commissioning and diagnostics. The achievable safety classification follows the selected evaluation: single-channel operation is limited to Category 3, PL d and SIL 2, while a valid two-channel structure can reach PL e and SIL 3.

Technical notes
Siemens 6ES7226-6BA32-0XB0 allows every a.x/b.x input pair to be assigned as one 1oo2 channel or two independent 1oo1 channels.

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.
When should 6ES7226-6BA32-0XB0 be configured as eight 1oo2 inputs instead of sixteen 1oo1 inputs?
Use the 1oo2 arrangement on 6ES7226-6BA32-0XB0 when the safety design requires paired evaluation; sixteen 1oo1 points remain separate single-channel inputs.
How are the physical terminals paired inside 6ES7226-6BA32-0XB0?
Siemens 6ES7226-6BA32-0XB0 pairs each a.x input with the corresponding b.x input, and every pair can be assigned independently as one 1oo2 channel or two 1oo1 channels.
Why can a 0.8 ms filter setting change the cable choice for 6ES7226-6BA32-0XB0?
At 0.8 ms, 6ES7226-6BA32-0XB0 requires shielded cable for the digital inputs and sensor supply, whereas longer documented filter settings allow the stated unshielded arrangement.
Which field-signal levels should be verified before connecting sensors to 6ES7226-6BA32-0XB0?
For 6ES7226-6BA32-0XB0, signal 0 is specified from -30 to +5 V DC and signal 1 from 15 to 30 V DC, so the sensor output must fit those windows.
What does an input LED confirm during commissioning of 6ES7226-6BA32-0XB0?
An input LED on 6ES7226-6BA32-0XB0 confirms the local state of that terminal; the project still determines whether the point is independent or part of a paired safety evaluation.
Can 6ES7226-6BA32-0XB0 reach SIL 3 with single-channel wiring?
No. The single-channel mode of 6ES7226-6BA32-0XB0 is specified to SIL 2; SIL 3 is tied to a valid two-channel configuration.
