Network Control Module 300

Series

IntroductionThe Network Control Module 300 Series (NCM300) is the main

processing module in the Metasys® Network. Fully programmable,

the NCM coordinates and supervises the control activities for all

objects and control loops connected to it via Network Expansion Units

(NEUs) and Application Specific Controllers (ASCs). Table 1 shows

the models available for the NCM300 Series.

This document also shows how to replace an NCM401 with an

NCM300.

Network Control Module 300 Series Technical Bulletin4

Table 1: NCM300 Series NCMs

Model Description

NCM300 (NU-NCM300-0, -1) The NCM300 is connected to the Metasys network via the

N1 ARCNET® Local Area Network (LAN).

NCM311 (NU-NCM311-1) The NCM311 is the European version of the NCM300. Construction

and operation are similar to the NCM300; however, there are minor modifications that

are required to conform with European Safety and Emission standards that apply in all

European Union countries.

NCM350 (NU-NCM350-1) The NCM350 is functionally the same as the NCM300; however, it

can connect to either an ARCNET or Ethernet LAN.

You can upgrade from an NCM300 either by swapping the NU-NCM300-0 for an

NCM350, or by upgrading an NU-NCM300-1 at Rev. B or later using the

NU-NCM300-1 to NU-NCM350-1 Upgrade Kit (NU-ROM150). Instructions come with

the upgrade kit.

Note: Do not attempt to upgrade NU-NCM300-1s at Rev. A hardware or any

revisions of NU-NCM300-0s to NCM350s. If you have already tried to upgrade one of

these models, choose one of the following options:

Replace the ROM SIMM with an NU-ROM101. The NCM is now an NCM300 suitable

for ARCNET applications only.

Return the NCM to the repair center for upgrade to NU-NCM350-1. Go to the Products

Focus tab and click on Repair Center > NCM3n0Upgrade on The Advisor for details.

The physical difference between the NCM300 and the NCM350 is a Flash chip in

place of the ROM chip. This Flash chip contains everything that is in the ROM, along

with configuration data. The Flash chip also contains information about the ISA drivers,

and the user can download additional information to the Flash chip.

NCM350-8 Updated version of the NCM350. Contains 8 MB total memory. Replaces all previous

versions of NCM300s and NCM350s. Meets UL 864 UUKL for smoke control

applications.

NCM361 (NU-NCM361-1) The NCM361 is the European version of the NCM350. You can

purchase the NCM361 new, or you can upgrade an NCM311 either by swapping the

NU-NCM311-0 for an NCM361 or by upgrading the NU-NCM311-1 using the

NU-NCM311-1 to NU-NCM361-1 Upgrade Kit (NU-ROM150). Instructions come with

the upgrade kit.

Construction and operation are the same as the NCM350; however, there are minor

modifications that are required to conform with European Safety and Emission

standards that apply in all European Union countries.

NCM361-8 Updated version of the NCM361. Contains 8 MB total memory. Replaces all previous

versions of NCM311s and NCM361s.

Fire-Net NCM (NU-NCM300-FIRE/NU-NCMFIRE-1) The Fire-Net NCM is connected to the

Metasys Intelligent Fire Network. It is physically the same as the NCM300; however, it

is UL 864 UOJZ Listed for fire alarm use. The NCM300-FIRE comes with a

preinstalled ARCNET board, 2 MB additional memory, and a special power supply.

The NU-NCMFIRE-1 is the same as the NU-NCM300-FIRE, except that it has 8 MB of

memory. For information on the Fire-Net NCM, refer to the Metasys Intelligent Fire

Network Technical Bulletin (LIT-448196).

Smoke Control NCM (NU-NCM300-2, replaced by NU-NCM350-8) The Smoke Control NCM is physically

similar to the NCM300; however, it is UL 864 UUKL Listed. For information on the

Smoke Control NCM, refer to the Smoke Control Technical Bulletin (LIT-636330).

Network Control Module 300 Series Technical Bulletin 5

Unless otherwise specified, the information in this technical bulletin

refers to all NCM models in the NCM300 Series.

NCMs described in Table 1 require Metasys Release 8.0 software or

later except for the NU-NCM300-0, which requires Release 6.0 or

later, and the NU-NCM350-8, which requires Release 9.01 or later to

use all 8 MB of memory. When using Release 10.0 or later, the

WINCSETUP Information view shows the NCM350-8 with 6 MB

RAM before a download and 8 MB RAM after download. The

problem occurs within the flash memory program code; the

NCM350-8 is not faulty (maintains 8 MB memory throughout

download).

An NCM, via the N1 LAN, also has the ability to control activities for

objects located in other NCMs. An example of exchanged control

would be objects shed or restored by the Demand

Limiting/Load Rolling feature.

Different program sets download to an NCM to support a variety of

devices on its local bus. The program sets are of two types: Standard

Functionality and Migration Functionality. The Standard Functionality

supports one of the following applications:

• Standard NCM software supports: NEU devices (XMs, DCM),

Heating, Ventilating, and Air Conditioning (HVAC) devices such

as Air Handling Units (AHUs), Variable Air Volume (VAV)

controllers, Variable Air Volume Modular Assemblies (VMAs),

Unitary (UNT) controllers, Lab and Central Plant (LCP)

controllers, DX-9100s, Intelligent Fire Controller (IFC) panel,

Extension Modules (XTM), Generic Vendor Devices (VNDs),

Metasys Integrator® units, and lighting application specific

controllers. For details, see NCM Software Options Technical

Bulletin (LIT-636023).

• Fire Management software integrates the fire alarm system

IFC panel (IFC-2020 or IFC-1010) to the Metasys network, as well

as supporting XMs and HVAC devices (listed above) on the

N2 Bus. In this configuration, the IFC panel operates as a

stand-alone fire alarm system, the NCM is part of the Metasys

Intelligent Fire Network, and is not UL Listed for fire alarm

(UOJZ) or for smoke control (UUKL) applications. The NCM

connected to the IFC panel serves as an ancillary annunciation link

between the IFC panel and the Metasys system.

Note: If you are using the Fire-Net NCM on the Metasys

Intelligent Fire Network, refer to Appendix A: Fire-Net NCM in this

document for details on the software used with the Fire-Net NCM.

Network Control Module 300 Series Technical Bulletin6

• Intelligent Access Controller software integrates the IAC-600

access controller to the Metasys network, as well as supporting

XMs and HVAC ASCs (listed above) on the N2 Bus.

• As an alternative to the portable Network Terminal (NT),

Operator Terminal software connects a VT100 (or a Personal

Computer with VT100 emulation software) to the NCM. An NCM

with an Operator Terminal connected also supports NEUs,

Intelligent Lighting Controllers (ILCs), and HVAC Application

Specific Controllers (ASCs) (listed above).

In addition, an Operator Terminal connected to one NCM on the

N1 network can display, schedule, and control Fire, Access, or

S2 applications connected to other NCMs on the network.

The Migration Functionality builds pathways from the NCM to other

systems. While it can support any of the Standard Functionality

program sets described above, the advantage to Migration

Functionality is that it connects one of the following applications to

the Metasys system:

• S2 Migration software brings JC/85® field gear, object

information, and control directly into the Metasys system from the

JC/85 trunks.

• JC/85 Gateway allows Metasys object information to integrate

with the JC/85 Central Processing Unit (CPU). In the Gateway

application, the NCM serves as a high-level protocol translator,

making Metasys object information available to a JC/85 headend.

• The Network Port software lets you monitor and control the

Metasys system from a third-party host. The host computer can be

any of the many types that can communicate with an

ALLEN-BRADLEY® PLC-5® Programmable Logic Controller

(PLC-5 Family). The host, in turn, communicates with the

Network Port, which emulates some features of a

PLC-5 controller.

For complete information on the Network Port, refer to the Network

Port Technical Bulletin (LIT-6295050).

Network Control Module 300 Series Technical Bulletin 7

Key Concepts

NCM The NCM is a microprocessor-based intelligent node in the

Metasys network. It integrates three streams of information:

• system and database information

• application programs

• data and Input/Output (I/O) information arriving from the

communication ports

Figure 1 illustrates the basic components and functions of the NCM,

including callouts referenced throughout this document.

Note: NCM350-8s do not have Single Inline Memory Module

(SIMM) banks on the circuit board. They are delivered from the

factory with their maximum 8 MB of RAM.

Memory

Each system has different memory requirements in terms of database

size and capabilities for processing information. Dynamic Random

Access Memory (DRAM) memory expansion is available through

industry standard SIMMs. The NCM is delivered from the factory with

2 MB of on board memory. This provides 580 KB of database memory

(which is approximately equivalent to an NCM200 with an NIM204).

Note: The NCM350-8 comes from the factory with 8 MB of

memory. Metasys Release 6.0 through Metasys Release 9.0 only

recognize it as having 6 MB of memory. Metasys Release 9.01

recognizes the full 8 MB of memory. SW1 and SW2 are not used on

the NCM350-8.

For the -0, -1, and -2 versions of the NCM300/350, Johnson Controls

provides four DRAM memory configurations: 2 (default), 4, 6, and

10 MB. The SIMMs (Item 1 in Figure 1) are located under the battery

pack. DIP switches on the board (Figure 1: Callout 2) set the memory

configuration that has been installed.

Note: Disconnect and remove the battery pack before servicing the

DRAM SIMMs.

Notes: 1 or 4 MB SIMMs should be 9 bits wide on a 30-pin SIMM with a speed rating of 100 nS or faster.

Three-chip SIMMs use less power than 9-chip SIMMs (this can extend your battery backup time). See Table 6

in this document.

Memory is always upgraded in pairs (banks) of SIMMs.

Memory switches are not used in the NCM350-8. The NCM350-8 comes with 8 MB memory.

Network Control Module 300 Series Technical Bulletin 9

Microprocessor

The microprocessor applies the various supervisory programs to the

combined data, and exercises control over the modules and devices

that connect to the NCM via a local bus.

This supervision and control operate in the same manner when any of

the Standard Functionality program sets (Standard, Fire Management,

Intelligent Access Control, or Operator Terminal) are downloaded.

For Migration Functionality, the microprocessor translates data from

the field gear into compatible code for the target system:

• For S2 Migration, the microprocessor integrates the incoming S2

data into the Metasys system and extends NCM supervisory and

control functions over the objects on the S2 trunk.

• For JC/85 Gateway, the NCM microprocessor:

- executes commands from the JC/85 headend to objects on the

Metasys software side

- provides attribute information for all objects on the

Metasys software side

- translates and sends Metasys software reports to the

JC/85 devices

• In Network Port applications, the microprocessor:

- translates the host-generated requests to Metasys software

commands

- applies the various supervisory programs to the combined data,

supporting those functions that relate to the mapping of data

objects to the host computer (mapped analog data and binary

data objects)

All the software applications and supervisory routines take place

inside the NCM; database exceptions and historical files are uploaded

to the Operator Workstation (OWS) for reporting and archival

purposes.

80-Pin SIMM Board

This circuit board (Figure 1: Callout 3) provides Read-Only Memory

(ROM) to the NCM. (For the NCM350 or NCM361, Flash memory

replaces the ROM.)

Communications

The I/O subsystem supports a multi-user environment consisting of

network connections (N1, integrated N2, and N2E) and direct I/O

communication (NT or Operator Terminal [OT], and RS-232 ports).

Network Control Module 300 Series Technical Bulletin10

Local Bus: N2 (Port 1)

The N2 Bus communications also are provided by a built-in interface

(Figure 1: Callout 6). Devices on the N2 Bus constitute a local

network, controlled by the NCM. The NCM polls the devices

according to a user-set priority level, which is set at each device’s

Definition window.

The N2 connects in a daisy-chain fashion and provides the

transmission medium for modules installed within the base frame

(for example, a Digital Control Module or Point Multiplex Module), as

well as the external devices (application specific controllers including

the AHU, UNT, VAV, VMA, LCP, DX-9100, IFC-1010/IFC-2020

Intelligent Fire Controller, and IAC-600 Intelligent Access Controller).

For information on setting N2 End-of-Line (EOL) switches, see

Setting the N2 End-of-Line Switches in this document.

ISA Bus Cards The NCM is equipped with two ISA slots. These slots can hold 16 bit

ISA cards (Figure 1: Callouts 4 and 5). These slots allow for the use of

off-the-shelf communication cards (either 8 or 16 bit).

Metasys Release 8.0 and later support the following communication

cards in the NCM ISA slots:

• ARCNET card (Slot 1 only)

• Ethernet card (NCM350 and NCM361 only [Slot 1 only])

• LONWORKS® interface card; Slot 2 only (Figure 1: Callout 5)

• Non Plug and Play (PnP) serial cards (if downloading is desired,

use the NCM350 or NCM361)

• Media Interface Board (MIB-OWS) must be placed in Slot 2

(Figure 1: Callout 5) (NU-NCM300-FIRE or NU-NCMFIRE-1)

PnP modems and devices are not compatible with NCMs unless the

PnP feature can be disabled. Most new internal modems are designed

to be PnP compatible. Note that the Information

Technology-Acquisition Services (ITAS) Personal Computer (PC)

price list (pcprices.doc) on The Advisor contains an updated list of

recommended modems. Please check the list prior to purchasing an

internal modem. You can find the list by searching for the file name,

pcprices.doc, on The Advisor.
