        Overview Manuals Input Voting Output Testing COM 95F Setup Unit Pairing

        Features:

        • Sixteen failsafe digital inputs can include two-out-of-three evaluation and line short-circuit testing.
        • Eight failsafe outputs are tested separately from the two groups of ordinary single-channel outputs.
        • STEP 5 control logic and COM 95F safety parameters occupy distinct engineering roles.
        The S5-95F arrangement pairs two identical basic units so safety-related processing can be compared across the system.

        Interrupt and counter inputs give the controller dedicated paths for time-critical and pulse-related safety functions.

        PG/OP/TD, SINEC L1 and PROFIBUS connections provide separate routes for engineering, operation and network exchange.

        The Siemens 6ES5095-8FB01 SIMATIC S5-95F Failsafe Programmable Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

        Evaluating safety-related field states

        • Failsafe inputs: Sixteen onboard channels carry the safety-related digital states into the controller.
        • Voting mode: Two-out-of-three evaluation lets three assigned signals be assessed as one safety decision.
        • Line test: The input short-circuit test is assigned to the relevant subunit rather than treated as a general wiring check.
        • Diagnostic result: Detected input or line faults are processed through the parameterized failsafe reaction.

        Separating failsafe and ordinary output paths

        • Safety outputs: Eight failsafe channels carry commands whose output path is checked by the controller.
        • Test interruption: Defined switch-off pulses expose faults that would otherwise leave an output continuously energized.
        • Standard groups: Two groups of four single-channel outputs remain distinct from the failsafe output set.
        • Program reaction: The configured error response determines how a failed output test affects system operation.

        Dividing control logic from safety parameters

        • STEP 5 program: The user control sequence is stored in the controller program area.
        • System parameters: COM 95F defines the safety-related operating data used by the basic units.
        • Startup behavior: Parameter settings control how the system enters operation after power-up or a detected fault.
        • Acceptance record: The COM 95F workflow supports checking and documenting the approved parameter set.

        Keeping both S5-95F basic units aligned

        • Order number: Both basic units in one system must carry the same documented order number.
        • Revision level: Matching hardware revisions keep the paired safety processing on the same unit design.
        • DI/DQ link: The failsafe link transfers the defined digital states used by the high-availability arrangement.
        • Shared diagnosis: A mismatch or communication fault must be evaluated as a system condition, not only as a local I/O fault.
        Description
        Siemens 6ES5095-8FB01 is the SIMATIC S5-95F failsafe programmable controller basic unit that reads safety-related field states, executes the STEP 5 control program and issues checked outputs within an S5-95F system. Two identical basic units are paired so their safety processing can be evaluated together.

        The sixteen failsafe digital inputs of 6ES5095-8FB01 accept the field signals used by the safety program. Two-out-of-three evaluation can be assigned where the input arrangement requires voting, while the subunit-specific line test checks the relevant input wiring for short circuits.

        Output control on 6ES5095-8FB01 combines eight failsafe digital outputs with two groups of four single-channel outputs. The controller interrupts its normal output state for defined test intervals so faults in the failsafe output path can be detected without treating the ordinary single-channel groups as safety outputs.

        Programming and parameter assignment follow separate paths on 6ES5095-8FB01: STEP 5 holds the control logic in the unit memory, while COM 95F defines system parameters, startup behavior, diagnostic reactions and acceptance data. The PG/OP/TD and network connections then link engineering, operator equipment and SINEC L1 or PROFIBUS communication to the controller.

        Technical notes
        Siemens 6ES5095-8FB01 uses COM 95F parameters to coordinate input voting, line tests and failsafe output test pulses. Verify the assigned field channels before acceptance testing.

        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.
        VIEW ALL FAQS
        Why must two 6ES5095-8FB01 basic units have the same revision level?
        An S5-95F system compares paired processing, so both 6ES5095-8FB01 units must have the same order number and revision level.
        When does 6ES5095-8FB01 use two-out-of-three input evaluation?
        The 6ES5095-8FB01 uses two-out-of-three evaluation only when three assigned failsafe input signals are parameterized to form one voting decision.
        What should be checked if 6ES5095-8FB01 reports a failsafe input line fault?
        For 6ES5095-8FB01, inspect the affected channel wiring and the subunit-specific short-circuit-test assignment before changing program logic.
        How are the ordinary outputs of 6ES5095-8FB01 different from its failsafe outputs?
        The 6ES5095-8FB01 has eight tested failsafe outputs plus two four-channel single-output groups that do not provide the same safety function.
        Which software holds the safety parameters for 6ES5095-8FB01?
        COM 95F stores and checks the system parameters for 6ES5095-8FB01, while STEP 5 is used for the controller program.
        Can operator panels exchange data with 6ES5095-8FB01 during failsafe operation?
        The 6ES5095-8FB01 includes function blocks for operator-panel or text-display connection with recording functions available in failsafe mode.
