Features:
- Dual-channel 16C552 UART architecture provides two independently controlled serial interfaces.
- Operating power is supplied directly through the associated M7 programmable or expansion module.
- Hardware identification uses the documented 41H interface-submodule identifier.
Siemens 6ES7962-3AA00-0AC0 is the IF 962-COM execution for compatible M7-300 and M7-400 hardware. Its compact plug-in construction adds serial connectivity without requiring an externally powered communication unit.
The submodule transfers data between the automation computer and established serial peripherals. Two separately addressed channels allow different devices to operate through the same M7 station.
Selection must preserve the correct submodule receptacle, COM-port mapping, connector wiring and application communication settings. Address and interrupt conflicts must be resolved before commissioning.
Availability is subject to exact part-number, hardware condition and M7 system compatibility confirmation by Apter Power.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Serial data exchange with operator terminals installed in M7-based automation and process-control stations.
- Connection of RS232-compatible modems for application-defined point-to-point communication tasks.
- Transfer of reports, status records or operating data to compatible serial printers.
- COMa is assigned to connector X1, while COMb is provided through connector X2 as a separately controlled channel.
- Each nine-pin Sub-D connection carries RS232C data, control, handshake and signal-ground lines.
- Transmission rates extend to 115.2 Kbps, with reliable performance dependent on cable construction and electrical interference.
- Both serial channels can operate in the AT-compatible address area or the reserved M7 I/O area beginning at C000H.
- Communication framing supports five to eight data bits, selectable parity and one, one-and-a-half or two stop bits.
- Each channel has a BIOS-assignable interrupt request; the documented defaults are IRQ4 for COM1 and IRQ3 for COM2.
- The submodule must be installed in a supported receptacle of an M7 programmable module or compatible EXM expansion module.
- Power must be switched off before inserting or removing the module or its connector, with ESD precautions observed throughout handling.
- Serial cables should remain within approximately 10 m, and process-side grounding measures may be required to prevent ground loops.
