Sepac - Model Scadapac CIC XAR2/4 -Compact Communication Controller Equipment

It transfers information to a local console through a Lan IEEE 802.3 and to the Superior Level Control Center via Modem, Radio-Modem, Microwave System, Power Line Carrier, etc.

Monitoring communication telegrams in the selected protocol, can be done using the RS232 port exclusively utilized for monitoring and configuration. Communication diagnosis and determination of kinds of errors can be obtained through this port. Also a real time event logger is automatically available.

Monitoring the Data Base makes equipment status available at all times.

Real time reading and modifying of the Data Base, table transfers, point selecting and grouping (considered virtual RTU data), can be sent to Superior Levels.

It allows timing  settings for pre and post transmission and adjustable timing for repeater applications on the different protocols installed.

It is a Communication Controller and Protocol Translator in the same piece of equipment.

The SCADAPAC-CIC XAR 2/4 is part of a family of products manufactured under the Integrated System concept. It’s functionality and performance under severe conditions make it highly reliable in Substation Automation applications.

ARCHITECTURE

Each SCADAPAC-CIC XAR 2/4 is dimensioned according to the specific characteristics of each system.

Each board that integrates the CPU is designed to withstand industrial environments.

The different SCADAPAC-CIC XAR 2/4 models can be delivered with RS232, RS485 or both ports; expandability is possible to a maximum of 32 channels increasing by two at a time.

CONNECTIVITY         

SCADAPAC-CIC XAR 2/4 is in charge of acquiring data from the systems coded on TCP/IP. Then it transmits them to Superior Level in the protocol required by  the Master Station.

Physical connection for radio communication can be done in two or four strings. To connect ports RS422 and RS232 we use a standard configuration  DB-9 connector.

BUILT IN CLOCK SYNCHRONIZATION

SCADAPAC-CIC XAR 2/4 can synchronize its built in clock through Lan network given the instruction from the local console, or through TCP/IP if the instructions come from the Master Station or a remote console.

Time can also be synchronized through an IRIG-B interface via satellite using GPS equipment.

SUB MASTER

SCADAPAC-CIC XAR 2/4 can communicate with RTUs from other manufacturers. It can be configured as a Sub Master to control several RTUs. i.e. pole RTUs, water well RTUs, remote modules from different manufacturers, etc.

When configured as a Sub Master, and communications on any channel should fail the SCADAPAC-CIC XAR 2/4 will ask the inferior module the same question a determined number of times. If it does not get an answer, it skips that module during the next scan unblocking the channel that is not working properly.

BACK-UP

SCADAPAC-CIC XAR 2/4 has the option of configuring a Main and a Back-up communication port.

Hot Standby redundant communication channel is made available, each time the back-up communication port is used.

PROTOCOLS

The equipment can operate with different protocols at the same time and/or several protocols of the same kind. Some of the main protocols SCADAPAC-CIC XAR 2/4 manages are:

• SCADAPAC V5.0
• DNP3.0
• HARRIS 5000/6000
• LEEDS & NORTHRUP
• LANDIS & GYR
• CDC
• WESTON RECON 1, II
• FUJI
• INDACTIC
• MODBUS +
• MMS

It also has capability of configuration of multiple addresses for each protocol.

The mentioned protocols can be managed in a master or remote configuration. In the master mode, scanning is made by the SCADAPAC-CIC XAR 2/4. In the remote mode, it responds to the scanning from Superior Level equipment.
