lntroduction

This document explains the Metasys Integrator Cleaver-Brooksapplication. Use this document with the Metasys Integrator technicalbulletins in the Metasys Connectivity Technical Manual (FAN 629.5)which provide information on installing and commissioning the MetasysIntegrator unit. For information on Cleaver-Brooks boiler control panels,see Cleaver-Brooks documentation (obtainable from a Cleaver-Brooksrepresentative).

Note: If you are using a Universal Packaging Module (UPM), you mustinstall the Metasys Integrator 300 Series in a two high enclosure(EN-EWC25-0) rather than a one high enclosure (EN-EWC13-0)as shown in the figures in this application note.

The Metasys Integrator unit allows Cleaver-Brooks equipment to becomean integral part of the Metasys and Metasys Companion Networks.Once either a CB-Hawk ASCII Interface or CB-General Purpose Interface(CB-GPI) and boiler control panels are connected to a Metasys orCompanion Network via the Metasys Integrator unit, their data is availableto the full complement of Metasys Building Automation System (BAS)features, including Change-of-State (COS) monitoring, alarm notification,trend, and totalization.

The CB-Hawk ASCII Interface allows information to be transmittedbetween CB-Hawk boiler control panels and non-Cleaver-Brooks devices(such as the Metasys Integrator unit). A six slot CB-Link is requiredbetween the CB-Hawk ASCII Interface and the boiler control panels.Optionally, you can connect a CB-Hawk Enhancer to Slot 6. However, ifyou use a CB-Hawk Enhancer, you must tie it into Slot 6, and you mustthen tie the CB-Hawk ASCII Interface into Slot 5 as shown in Figures 1and 2.

Each Metasys Integrator vendor port can connect to one CB-Hawk ASCIIInterface. Each CB-Link can connect to five CB-Hawk boiler controlpanels, or four CB-Hawk boiler control panels and one CB-HawkEnhancer.

Figure 1 shows a Metasys Network with the Metasys Integrator unitconnected to one CB-Hawk ASCII Interface. Four CB-Hawk boiler controlpanels connect to the CB-Hawk ASCII Interface through Slots 1 through 4on the CB-Link. A CB-Hawk Enhancer connects to Slot 6 on the CB-Link.Figure 2 shows a similar Cleaver-Brooks configuration integrated into aMetasys Companion Network.

Figure 2: Cleaver-Brooks CB-Hawk Boiler Control Panel andMetasys Companion Integration (CB-Hawk ASCII Interface)

You can also integrate Cleaver-Brooks equipment with the Metasys andMetasys Companion Networks through the CB-GPI. This interface resideson an RS-485 bus. The CB-Link communicates with up to fiveCB-Hawk/CB-780 boiler controls and, optionally, a CB-Hawk Enhancer.

The RS-485 connects to a Johnson Controls RS-232 to RS-485 converter(MM-CVT101) which connects via an RS-232 cable to the MetasysIntegrator panel. The Metasys Integrator unit can receive data from, andsend data and commands to, Cleaver-Brooks equipment.

Each Metasys Integrator vendor port can connect to one RS-232 to RS-485converter which can connect by RS-485 bus to one CB-Link.

Install the CB-GPI in Slot 6 of the CB-Link, unless a CB-Hawk Enhanceris present. If a CB-Hawk Enhancer is present, you must install it in Slot 6,and you must install the CB-GPI card in Slot 5. The number of boilercontrollers that you may connect is then reduced to four.

When integrating Cleaver-Brooks equipment, keep the followingconsiderations in mind:

• Make sure all Cleaver-Brooks equipment is set up and runningproperly before attempting to integrate with the Metasys orCompanion Network. (The Cleaver-Brooks representative isresponsible for operation of CB equipment.)

• RS-232 cable distance between the Metasys Integrator unit and theCB-Hawk ASCII Interface or the Johnson Controls MM-CVT101 is amaximum of 50 feet.

• Cable distance between the CB-GPI and MM-CVT101 can be amaximum of 1000 feet.

• The CB-780 Burner Control and the CB-783 Expanded Annunciatorfor a given burner must be commissioned to the same slot (they musthave the same vendor address).

• When using the CB-GPI with a CB-Hawk, configure the CB-Hawk as“Setback Capable = Yes.”

• When using the CB-GPI with an Enhancer, follow these instructions:

1. Disconnect the Metasys Integrator unit.

2. Connect the 9-pin female connector to a PC Commissioning portusing the RS-485 CVT-101 cable configured for a MetasysIntegrator unit.

3. Configure a terminal emulator for 9600 baud, 8 bit, 1 stop bit, noparity.

4. Enter this command in lower case to set the GPI to its defaultvalues:

sz zap

5. Enter this command in lower case to set the reply timeout to8 seconds:

Metasys Integrator Setup

To set up the Metasys Integrator unit, use a portable PC connected to theMetasys Integrator Terminal Port. The Metasys Integrator unit setupinvolves:

• downloading the correct vendor communication table (.VCT file)

• setting up the port

• setting up the network addressing

The following table provides information specific to the Cleaver-Brooksapplication. For detailed procedures, see the Metasys Integrator technicalbulletins.

If your system has a CB-Hawk Enhancer option, you need to downloadthe .VCT files required for the CB-Hawk Boiler points, CB-HawkEnhancer Boiler points, and the CB-Hawk Enhancer general points. If youare not using a CB-Hawk Enhancer, you need only the CB-Hawk points.

Point Mapping Tables

The following tables show the CB-Hawk boiler control points. The pointsavailable for mapping depend on the type of equipment you are using. Ifyou use only boiler control panels with an ASCII interface, use Table 2. Ifyou also have a CB-Hawk Enhancer, use the points shown in Tables 2, 4,and 5. The CB-Hawk Enhancer points have been split into two groups:CB-Hawk Enhancer Boiler Points (Table 4) and CB-Hawk EnhancerGeneral Points (Table 5).

CB-780ControllerPoints

To get the hardwarereference formapping points toCS object attributes(via the softwaremodel), combine theNPT (Network PointType) and NPA(Network PointAddress). Forexample, thehardware referencefor Test/Run Switchis BI1.

ADI points (internalparameters) cannotbe mapped tostandard objects.To monitor thesepoints, map them toCS object ADattributes (whichcan then bemapped to standardobjects).

Metasys Network Setup

Metasys Network Setup is described in the Metasys Integrator technicalbulletins. This section contains details specific to Cleaver-Brooksapplications.

Table 8 lists the software model files and the recommended Display andNetwork Terminal (NT) Command Attributes.

Whether all the models shown in the table are needed depends on theequipment used. For example, if the system has only boiler control panels(and no CB-Hawk Enhancer), only the model file for boiler control pointsis needed. If the system has a CB-Hawk Enhancer and an ASCII interface,all the three ASCII model files are used.

The CB-Hawk Enhancer points are split into two groups:

• CB-Hawk Enhancer boiler points and

• CB-Hawk Enhancer general points

The point mapping tables show how the points are categorized.

1 Whether you use the AI1 or AI2 point depends on whether your system has asteam boiler or a hot water boiler.

2 For the NT Command attribute, use the same attribute as the Display attribute.However, since the CB-780 and CB-783 points are not commandable, you will notbe able to command the attribute. (This must be defined, because the NTCommand attribute cannot be null.)
