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), RS232 converter, 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.
