Features:
- Siemens 6MF1013-0CF51-0AA0 is the SM-2551 two-interface serial processor identified by item code BC2-551.
- The module uses X2 and X3 on a CP-2016 or CP-2019 carrier for its two serial communication paths.
- Both interfaces are galvanically separated from the logic circuits and from each other.
The carrier position places
6MF1013-0CF51-0AA0 between the supplementary system-element bus and the external serial connection. Operating power enters from the carrier rather than a separate terminal.
Each path on
6MF1013-0CF51-0AA0 can handle byte-asynchronous or byte-isochronous pulse-code operation. The supported interface characteristics are selected with the relevant protocol configuration.
When parallel wiring is used,
6MF1013-0CF51-0AA0 places outgoing signals in tristate operation while keeping incoming circuits active. The V.28 cable limit then changes with the selected bit rate.
The Siemens 6MF1013-0CF51-0AA0 SICAM AK 3 SM-2551 Serial Interface Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Two Serial Channels on the Carrier
- Channel count: 6MF1013-0CF51-0AA0 provides two independent serial communication circuits.
- Connector X2: The first serial path reaches the external connection through X2 on the carrier module.
- Connector X3: The second serial path uses X3, keeping the two communication paths separately identifiable.
- Protocol setting: Electrical characteristics and signal assignments follow the selected protocol mode rather than a single fixed pin function.
Signal Behaviour in a Shared Connection
- Parallel limit: Up to two interfaces can be connected in parallel for the supported operating mode.
- Outgoing path: Transmitted interface signals use tristate technology so their driven state can be controlled.
- Incoming path: Receive circuits remain active while the outgoing side changes state.
- Mode selection: Byte-asynchronous and byte-isochronous pulse-code modes are selected through the applicable protocol configuration.
Separated Signal and Auxiliary Paths
- Logic separation: Serial signals are galvanically isolated from the module logic circuits.
- Channel separation: The two interface circuits are also galvanically isolated from each other.
- Gate voltage: A carrier-supplied 4.7–5.6 V DC gate voltage can be selected instead of the DSR signal.
- Protection limit: The gate-voltage output is neither short-circuit-proof nor overload-proof, so the connected load must remain within its stated limit.
How the SM-2551 Fits the Basic Element
- Supported carriers: The SM-2551 is installed on CP-2016 or CP-2019 basic system elements.
- Power source: The carrier supplies 4.75–5.25 V DC to 6MF1013-0CF51-0AA0.
- Current budget: Carrier planning must allow 300 mA typical and 540 mA maximum at 5 V.
- Cable-rate relation: V.28 permits up to 25 m at 50 bit/s but only up to 5 m at 115200 bit/s.
