ABB SPNPM22 Network Processing Module

SPNPM22 Network Processing Module

The SPNPM22 network processing module is the gateway between Cnet and Control way. It holds the Harmony control unit (HCU) database and directs the communication process between the modules residing on Control way and the SPNIS21 module.

Two latching fasteners on the faceplate secure the SPNPM22 module to the MMU. There are 16 LEDs on the faceplate (8 red and 8 green), a Status LED, and a Stop/Reset push button.

The SPNPM22 module has a 16-byte module status record. The status report provides summary flags for error conditions, module type, and firmware revision level.

The status report can be viewed from a human system interface. You need to convert each hexadecimal byte to the binary equivalent to interpret the status bytes.

The SPNPM22 Network Processing Module acts as a gateway between Cnet and Control way. The module holds the HCU database and directs the communication process between the modules residing on Control way and the SPNIS21 module. The module is a single printed circuit board that occupies one slot in a MMU. The circuit board contains microprocessor based communication circuitry that enables it to directly communicate with its SPNIS21 module over a dedicated I/O expander bus and to interface to Control way.

The SPNPM22 module has two card edge connectors for external signals and power (P1 and P2). Connector P1 connects to common, +5 VDC power, and Control way. Connector P2 connects the SPNPM22 module to the I/O expander bus to communicate with the SPNIS21 module.

Block Diagram

The following figure shows a functional block diagram of the SPNPM22 module. The module primarily contains a central processing unit(CPU), memory, and I/O expander bus and RS-232-C serial channel interfaces. Refer to sub-section 2.2.1.4- I/O Expander Bus of this user manual for an explanation of the I/O expander bus interface.

CPU

The CPU contains a 32-bit microprocessor running at 160 megahertz and associated support circuitry (i.e., control logic, address decoder, interrupt interface, system timer, etc.). The CPU interprets and executes instructions to perform the computer interface functions, control communication, and run diagnostics. Since the microprocessor is responsible for overall module operation, it communicates with all the functional blocks.

Memory

The SPNPM22 module memory consists of ROM memory and RAM memory. The ROM memory holds the operating system instructions for the microprocessor (i.e., firmware). The RAM memory provides temporary storage and a copy of the exception report route database records.

Controlway

Control way provides a one-mega baud, peer-to-peer communication link capable of supporting up to 32 connections. There are two separate communication paths on the MMU backplane for Control way communications. Data is transmitted over both channels simultaneously and received in separate receivers where it is checked for integrity. In this way, the Control way minimizes the chances that a failure on a circuit board or the backplane will cause loss of module communication. As point data between intelligent modules travels on the bus, the module performs a bit-by-bit comparison.
