About the BMX NOR 0200 H Module

Overview

The BMXNOR0200H module brings Remote Terminal Unit functionality to the Modicon Mx80 PAC platform.

The RTU system provides an extensive set of control and communications features including industry and telemetry standard protocols such as IEC 60870-5-101, IEC 60870-5-104, DNP3 and Modbus TCP.

About the Module

The BMXNOR0200H module is a ruggedized module, designed for installation and operation in harsh environments and extended operating temperature ranges.

For more detailed information, refer to Modicon M580, M340, and X80 I/O Platforms, Standards and Certifications.

The Modicon Mx80 PAC platform offers these features for telemetry applications:

operations in extended temperature ranges and harsh environments
in-rack RTU module with support for IEC 60870-5-101/104, DNP3, and Modbus TCP
specialized function blocks (AGA, flow calculations)
expandable rack-based modular I/O configurations and remote I/O capabilities
high-density, discrete, analog, and I/O counting modules
isolated input power supply (various voltage ranges available 24 Vdc, 24/48 Vdc, 125 Vdc, 100/240 Vac)
built-in CPU and modules with serial and Ethernet communication ports
support for Modbus TCP
local or remote downloading of operating system firmware

The BMXNOR0200H module addresses a wide range of telemetry requirements:

conformal coating and extended operating temperature ranges
various communications methods
- serial and TCP/IP networks
- intranet
- WAN
- modem connections
various modem connections
- serial and radio modems
- GSM and PSTN modems
- IP modems (GPRS, ADSL)
upstream communications with SCADA master stations for polling interrogation of data, backfilling of time stamped event data, receiving master commands
downstream communications with other RTU substations, slave field devices and IEDs (for data collection), sending commands, and synchronizing distributed control
remote programming and downloading of control program with Control Expert software through Ethernet or modem connections
remote diagnostic and monitoring with a built-in Web server

Functions and Protocols

The BMXNOR0200H module supports these functions and protocols:

RTU protocols:
- Built-in RTU protocols for serial or Ethernet communications
- IEC 60870-5-101 (master or slave)
- IEC 60870-5-104 (client or server)
- DNP3 serial (master or slave)
- DNP3 IP (client or server)
- Modbus TCP (client or server)
Main RTU Protocol Features
- Time synchronization through protocol facility or NTP
- Data synchronization on demand of the SCADA
- Balanced and unbalanced transmission mode
- Events management with time stamping - Sequence of Events (SOE)
- Events queue stored in RAM memory (up to 100,000 events for all clients)
- Events data backfill to SCADA application via protocol facility
- Report by exception data exchanges
- Unsolicited messaging data exchanges
- Protocol setup via Web page
Other built-in functions
- Historical DataLogging with time stamping inside the module SD memory card
- Email/SMS notifications
- Web server for RTU set-up and remote diagnostic and monitoring
- Advanced TCP/IP networking: NTP client, FTP client, or server, HTTP server, SOAP/XML, communication server, SNMP agent, SMTP client.

NOTE: When the BMXNOR0200H module works as IEC-104/DNP3 Client, the number of connected servers affects the module performance (webpage access, module start-up and data exchange through the backplane.)
