Protocol Converter Is The Key Component In Communication

Share

The Protocol Converter, a device converts one protocol into other protocol, is ideal for situations where data from monitored equipment is incompatible with the protocols used by the building management system (BMS) or network management system (NMS), such as in cases where legacy monitoring systems are present. The ability of the protocol converter to accept up to 1,024 inputs over 32 modules means flexible integration with multiple alarm and management systems using one simple device. Protocol converters are widely used in process or industrial automation, building automation, substation automation, automatic meter reading and vehicle automation applications.

Protocol converters are normally used with switches, PCIe network cards and fiber media converters, CWDM and DWDM equipment, PDH multiplexers etc. Protocol converter series may put into action the actual transformation in between single E1 protocol port as well as protocol ports of V.35, V.24, RS232 or Ethernet within the tranny system; it may be thoroughly utilized in numerous being able to access problems with regard to providers as well as commercial clients, for example DDN, ATM, as well as for that transformation in between router and E1 port, or even the actual occasion exactly where Ethernet tend to be interconnected from divided internet websites through SDH or even additional tranny gear.

1. Protocol converter can offer local, remote loop-back functions, commanded remote device loop-back as well as pseudo-random code testing perform; loop-back perform may be used without influence on normal network data conversation and can not really lead to the actual meltdown of network;

2. E1 port may support 120ohm/75 ohm opposition concurrently;

3. V.24 port may assistance a rate of 64K or 128K (optional), and may carry out tranny from any kind of specific time-slot within E1 port; also it can function under DTE and DCE modes;

4. V.35 user port may support N*64K (N=1~32) adaptive rate, and may assistance inner, exterior and slave clock modes, in order to end up being designed in order to numerous programs; also it can function under DTE and DCE modes;

5. RS232 port may assistance the actual a good adaptive rate lower than 115.2K;

6. Ethernet port may assistance N*64K (N=1~32) adjustable rate, and may assistance four channels of Switched Ethernet ports and may end up being channel-isolated; Ethernet mode may assistance 10M/100M semi-duplex as well as 10/100M full-duplex modes as well as adaptive mode (optional), as well as assistance VLAN protocol;

7. Ethernet protocol convertor may identify the actual delivering as well as getting information caution associated with E1 port instantly, as well as switch off Ethernet function instantly.

How To Choose A Converter

There are basically two types of protocol converter which are listed below.

1. Software Protocol Converters
2. Hardware Protocol Converters

Some of the most popular industrial automation protocols are DF-1, CAN (Controller Area Network), Ethernet RS232 Converter, Ethernet RS422 Converter, ControlNet, DeviceNet, HostLink Protocol, Profibus, Modbus, Honeywell SDS, HART Protocol, EtherNet/IP etc. And some Industrial control system protocols like MTConnect, OPC, OPC UA. Select the converter that best matches your application and communication setup, keeping in mind three key features:

Number of connections—some converters support single connections, while others provide as many as 32 multiple connections with multiple serial ports.

Baud rate—we have seen converters with baud rates as high as 921kbaud. Converters with lower baud rates are less expensive, but their performance is slower.

Connectivity protocol—the converter must support the protocol used by your network, either TTL serial, RS-232, RS-422, or RS-485.

Consider the number of connections, baud rate and connectivity protocol, you can finally buy a protocol converter meet your applications.

Devices Can Communicate Directly With A Protocol Converter

Protocols are determined by several factors such as data rate, encryption methods, file and message formats and associated service. A protocol converter is tasked with taking this protocol and changing it to another one, making devices connected across these networks to communicate directly. Protocol converters, much like a language translator, translate messages or data streams between networks, to enable both networks easily interpret the data.

Protocol converter is a highly beneficial device used by various industries in order to convert the proprietary or standard protocol of a device into suitable protocol of other tools or device in order to attain inter compatibility. Within a network, the large number of different machines and there is a possibility that different machines will run on different protocols. This can make work difficult, because most protocols are inherently incompatible with one another, thus preventing machines with different protocols from integrating. By using a protocol converter, users can bypass this difficulty by changing the protocol, which allows the different machines to work together — as long as the converter supports the protocols of each machine.

The most attractive benefit of the protocol converter is that the users can carry out the networking and serial communication without even bothering about the programming performed at the hardware level. Without the need of any additional programming for the end user, the protocol converter manages well to transmit the transparent data along the channel which connects a combination of two communication ports. Another key feature of the protocol converter is that of being a programmable driver.

Most protocol converter units are programmed to understand a handful of different protocols, and these units use an internal database to track all the protocols. This database will store all the factors associated with the known protocols, and the database also is tasked with helping this device understand what needs to be changed to alter one protocol to another. Unlike regular databases, which can be manually updated, this database typically is locked from users.

Typical types of protocol converters include E1 to Ethernet, V35 to Ethernet and E1 to V35.

The E1 protocol converter is used to convert E1 signal to 10/100Base-T Ethernet signal, and vice versa. It extends the bandwidth to 7.68Mbps. It can be used in two LAN connection, remote monitor or video broadcasting.

E1 to V35 protocol converter realizes the bi-directional data transfer from E1 port to V. 35 network. This equipment is used in communication network including WAN and LAN, realizing the transfer from E1 channel of SDH or PDH equipment to V. 35, which maybe provided by routers.

V35 to Ethernet Protocol Converter accomplish the converting between the 10/100M Ethernet port and the V. 35 port. It provides at most bandwidth N*64kbps data transmission channel for Ethernet through V. 35 Lines. It is suitable for many situations, such as increasing the range of LAN, founding a special Ethernet network, and so on.

The protocol converters have the capacity to support the Modbus ASCII, Modbus RTU, Modbus TCP and the RFC-2217, E1, Ethernet, V.35, RS232, RS422 and beyond. There are protocol converters that even allow great solution developers the ability to add the proprietary applications and protocols. Also there are converters like RS422 converter and RS232 Ethernet converter available.
