2 INTRODUCTIONElectrical Teleprotection is an optional feature that uses communications links to create protection schemes. It canbe used to replace hard wiring between dedicated relay output contacts and digital input circuits. Two productsequipped with electrical teleprotection can connect and exchange commands using a communication link. It istypically used to implement teleprotection schemes.Using full duplex communications, eight binary command signals can be sent in each direction betweenconnected products. The communication connection complies with the EIA(RS)232 standard. Ports may beconnected directly, or using modems. Alternatively EIA(RS)232 converters can be used for connecting to othermedia such as optical fibres.Communications statistics and diagnostics enable you to monitor the integrity of the communications link, and aloopback feature is available to help with testing.Chapter 17 - Electrical Teleprotection P14x372 P14xEd1-TM-EN-1
