F860-CA HONEYWELL Series C “fieldbus interface module

Description

Overview

Essential details：F860-CA HONEYWELL Series C “fieldbus interface module

Product Description

The F860 is designed to provide redundant power to eight foundation fieldbus H1 segments when used with the Honeywell Experion “Series C” Fieldbus Interface Module (fim). Module brackets comply with 11.6
The mechanical and electrical requirements of the inch I/O Terminal Assembly (iota) can be installed directly into the Honeywell installation channel.
The fieldbus segment is powered by two redundant power modules f801 or f802. Fault warning, current isolation, power regulation and segment termination are incorporated into each F80x module. In simplex applications, can
To use a single F80x module. Automatically maintains the termination of the fieldbus segment when a single or redundant F80x module is installed.
To ensure high reliability, the F860 IOTA uses passive mode and provides only power modules to connect to external connections.
IOTA has two multi-pin connectors, each connected to FIM IOTA via a standard system cable.
Different lengths are available to accommodate the installation of the F860 and its respective FIM iota in different locations within the series C /O cabinet. Field wiring is connected at FIM IOTA.

CAN bus uses serial data transmission mode, can run on 40m twisted pair at 1Mb/s rate, can also use optical cable connection, and on this bus bus protocol supports multiple master controllers. CAN is similar to the l2C bus in many details, but there are some obvious differences.

When a node (station) on the CAN bus sends data, it is broadcast in the form of a message to all nodes in the network. For each node, data is received regardless of whether it is sent to it or not. The 11-bit character at the beginning of each set of messages is an identifier that defines the level of the message. This message format is called content-oriented addressing scheme. Identifier in the same system Yes, it is not possible for two stations to send a message with the same identifier. This configuration is important when several stations simultaneously compete for bus reads. When a station wants to send data to other stations, the CPU of the station will send the data and its own identifier to the CAN chip of the station, and is in a ready state; When it receives the bus assignment, it switches to the sending message state. The CAN chip organizes the data into a certain message format according to the protocol and sends it out. At this time, other stations on the network are in the receiving state. Each station in the receiving state checks the received packets to determine whether the packets are sent to it, and then determines whether to receive them.
