Description
The SIEMENS 6DS1220-8AB N8-H Local Bus Interface is a local bus interface module from the Siemens TELEPERM M / ME distributed control system family. It serves as the critical communication bridge between the central processing unit and the local I/O modules in TELEPERM M automation systems.
The "N8" designation indicates an 8-bit local bus interface operating on the CS275 bus system, which is the standard communication backbone of the TELEPERM M system. The "H" suffix signifies that this module is designed for fault-tolerant operation in a redundant automation system configuration. Specifically, the N8-H implements a 1-out-of-2 master/reserve (1oo2) redundancy scheme, where two CPU modules operate in parallel with one acting as the active master and the other as a hot standby reserve.

Visual Check: Once installed and powered on, check the status LEDs. Proper operation is typically indicated by a steady or flashing LED pattern as defined in the system's reference manual.
Software Recognition: Use your system's engineering tool (such as PROGRAF AS) to verify the interface is recognized by the central controller.
Technical notes
In the N8-H configuration, the local bus interface supports three CPU operating modes: Master (M), where the CPU has full control of the N8-H bus access; Standby (R), where the CPU is ready to take over as master; and Passive (P), where the CPU operates asynchronously without N8-H bus access. Automatic switchover from master to standby occurs upon detection of a failure in the active master CPU, ensuring continuous system operation without interruption.
