Functional Description

IS220PCNOH1A is a CANopen Master Gateway Module developed by GE.

It is a part of Mark VIe series. The CANopen Input/Output pack is an NMT

CANopen master that maps I/O from CANopen Woodward GS6 and GS16 valves to MarkVIe controllers via I/O Ethernet.

The CANopen I/O pack (PCNO) is a network management master that maps CANopen I/O to IONet Mark VIe controllers.

The PCNO I/O pack includes a BPPx processor board and an acquisition carrier board outfitted

with a Hilscher GmbH COM-C CANopen communication module.

The CANopen fieldbus interface is provided by the COM-C module via a DE-9 D-sub receptacle connector.

It functions as a CANopen master with a maximum transmission rate of 500 kbps.

The PCNO supports the redundancy two options.

Single I/O pack with a single I/O Ethernet connection (no redundancy) and dual I/O Ethernet connections

Features

The module includes a processor board that is shared by most Mark VIe distributed I/O modules

and an acquisition carrier board outfitted with a Hilscher GmbH COM-C CANopen communication module.

The CANopen fieldbus interface is provided by the COM-C module via a DE-9 D-sub receptacle connector. 

It functions as a CANopen master with a 500 Kbaud transmission rate that communicates with one to five Woodward GS6 or GS16 valves.

The following redundancy options are supported by the PCNO:

One I/O pack with one Ethernet connection (no redundancy)

Dual I/O Ethernet connections on a single I/O pack

Compatibility

The SPIDG1A CANopen Master Gateway Terminal board is used to mount the PCNO and provide an electronic ID.

Its only connection is to the PCNO, as the CANopen connection is made to the DE-9 D-sub receptacle connector exposed on the PCNO's side. 

On the PCNO, indicator LEDs provide visual diagnostics.

Processor

The processor board is shared by all Mark VIe Ethernet I/O packs or modules. It includes the following:

Two fully independent 10/100 Ethernet ports with connectors

High-speed processor with RAM and flash memory

Hardware watchdog timer and reset circuit

Internal temperature sensor

Status LEDs

Soft start/current limiter on the input power connector

Local power supplies, including sequencing and monitoring
