Common industrial network protocol – Foundation Fieldbus
This protocol is developed by the International Society of Automation (ISA). Its application areas include petrochemicals, food and beverages, power, and other heavy-process applications. It is used to connect foundation Fieldbus-enabled devices such as sensors/transmitters to a control system with less wiring. It allows several Fieldbus devices to use a single cable.
Two types of foundation Fieldbus implementation are Foundation Fieldbus H1 and Foundation Fieldbus High-Speed Ethernet (HSE):
- Foundation Fieldbus H1: This version provides speeds of up to 31.25 Kbps. Twisted pair cables and fiber optic cables can be used as network media. It provides digital communication and DC power over the same twisted pair. It is implemented using a bus or star topology. Its network can have up to 32 nodes per segment. It is used for communication between several sensors/transmitters and actuators (field devices) and a PLC...
