Chapter 1 Module Overview

Section 1.1 General Description

The 2080sc-BAC Communication Module is a two-channel communication, plug-in module for use with Rockwell Automation Micro800™ systems.
The plug-in module supports two channels of data communications: one channel is configured for RS-485, half duplex serial communications, and the other channel is configured for 10/100M Ethernet full duplex serial communications. After installation, the module is configured via the Ethernet port. By default, this is the port that the module uses to communicate with external devices such as other BACnet modules or personal computers.
The module plugs into an extension slot on the PLC. The module interfaces with the controller via Asynchronous Parallel Interface (API), and communicates with other BACnet modules using the BACnet protocol. The module stores the data internally. During module setup, you map Micro800 PLC tags to BACnet tags so that the Micro800 system is able to receive, and respond to, BACnet messages. The BACnet protocol is configured to run on the Ethernet port by default.
The data exchanged between a module and controller, or other BACnet modules, includes module configuration, configuration changes, interrupts from the module to the controller, module status queries from the controller, controller reset commands to the module, and other associated communications.
The BACNet configuration software resides on the BACNet module. You use a

WARNING
This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters (6562 feet) without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate precautions, there may be potential difficulties ensuring electromagnetic compatibility in other environments due to conducted as well as radiated disturbance.
This equipment is supplied as open-type equipment. It must be mounted within an enclosure that is suitably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. The enclosure must have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with a flame spread rating of 5 VA, V2, V1, V0 (or equivalent) if non-metallic. The interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this publication may contain additional information regarding specific enclosure type ratings that are required to comply with certain product safety certifications.
In addition to this publication, see: Industrial Automation Wiring and Grounding
Guidelines, Allen-Bradley publication 1770-4.1, for additional installation requirements.
NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure.
web browser to access this software to configure the parameters for the module. Configuring the communication module includes setting the User Interface
password, entering the module device address, IP address, serial baud rate, and mapping PLC tags to BACnet tags. For complete information, refer to Chapter 3, Configuring the Module using Software.
Power for the module is provided across the backplane. MS/TP signals from the field side are connected to the module via the 6-pin connector (RS-485). The Ethernet port handles BACnet/ IP traffic.

WARNING
Cet équipement est prévu pour fonctionner en environnement industriel avec une pollution de niveau 2, dans des applications de surtension de catégorie II (telles que définies dans la publication 60664-1 de la CEI) et à une altitude maximum de 2000 m sans déclassement.
Cet équipement est considéré comme étant un équipement industriel du Groupe 1, classe A selon
CEI/CISPR 11. En l’absence de précautions
appropriées, des problèmes de compatibilité électromagnétique peuvent survenir dans des
environnements résidentiels et dans d’autres
environnement en raison de perturbations conduites et rayonnées.
Cet équipement est fourni en tant qu’équipement de
type « ouvert ». Il doit être installé à l’intérieur d’une armoire fournissant une protection adaptée aux
conditions d’utilisation ambiantes et suffisante pour éviter toute blessure pouvant résulter d’un contact
direct avec des composants sous tension.
L’armoire doit posséder des propriétés ignifuges capables d’empêcher ou de limiter la propagation des
flammes, correspondant à un indice de propagation de 5VA, V2, V1, V0 (ou équivalent) dans le cas
d’une armoire non métallique. L’accès à l’intérieur de l’armoire ne doit être possible
qu’à l’aide d’un outil. Cette armoire doit permettre des connexions d’alimentation par un système de
câblage de Classe I, Division 2, conformément au code électrique national (NEC). Certaines sections de la présente publication peuvent comporter des
recommandations supplémentaires portant sur les indices de protection spécifiques à respecter pour maintenir la conformité à certaines normes de sécurité.
En plus de cette publication, consultez :
La publication Rockwell Automation 1770-
4.1, « Industrial Automation Wiring and Grounding Guidelines », pour d’autres critères d’installation ;

Electrostatic discharge can damage integrated circuits or semiconductors if you touch bus connector pins. Follow these guidelines when you handle the module:
Touch a grounded object to discharge static
potential.
Wear an approved wrist-strap grounding
device.
Do not touch connectors or pins on
component boards.
Do not touch circuit components inside the
module.
If available, use a static-safe work station.
When not in use, keep the module in its
static-shield box.
WARNING
Cet équipement est sensible aux décharges électrostatiques, lesquelles peuvent entraîner des dommages internes et nuire à son bon onctionnement.
Conformez-vous aux directives suivantes lorsque vous manipulez cet équipement :
Touchez un objet mis à la terre pour vous
décharger de toute électricité statique éventuelle ;
Portez au poignet un bracelet antistatique
agréé ;
Ne touchez pas les connecteurs ni les broches
figurant sur les cartes des composants ;
Ne touchez pas les circuits internes de
l’équipement ;

WARNING
Pour se conformer à la Directive basse tension CE,
cet équipement doit être alimenté à partir d’une
source ayant les caractéristiques suivantes: très basse tension de sécurité (TBTS) ou très basse tension de protection (TBTP).
WARNING
This equipment is considered Group 1, Class
A industrial equipment according to IEC/CISPR 11. Without appropriate precautions, there may be difficulties with electromagnetic compatibility in residential and other environments due to conducted and radiated disturbance.
Be careful when stripping wires. Wire
fragments that fall into the controller could cause damage. Once wiring is complete, make sure the controller is free of all metal fragments before removing the protective debris strip.
Do not wire more than 2 conductors on any
single terminal.
If you insert or remove the plug-in module
while power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.
Cable length should be less than 10 meters
(30 feet).
Do not insert or remove the plug-in module
while power is applied; otherwise, permanent damage to equipment may occur.

Section 1.4 Parts List

Your package contains one Micro800 BACnet Communication Module, installation screws, and one Quick Start Guide.
You can choose to wire the plug-in before inserting it into the controller, or wire it once the module is secured in place.

Section 1.6 LED Indicator

A single LED indicator is provided with the module. The LED is green for ON. The LED blinks in case of a fault.

Section 1.7 Software Upgrade

The module software can be upgraded in the field.

Section 1.8 Module DC Power Specifications

The controller provides two Power Supplies to the module:
3.3 Volts (3.0 V Min, 3.6 V Max), Current Rating: 40 mA 24 Volts (20.4 V Min, 26.4 V Max), Current Rating: 50 mA
You may not use an external power source to power the module. Refer to the specifications in the Appendix for further information.

Section 1.9 Module Chassis Earth Ground

The Micro800 controller does not have a chassis (earth) ground. The 2080sc­BACnet module connects to an isolated ground, ISO-GND, which is exclusive to the external communication interfaces. The purpose of the isolated ground is to prevent possible interference on the I/O channels from permanently damaging the module itself.
