CAN I/0 Bus

Open CAN -Bus，up to 1 MBd

Foundation Fieldbus H1

up to 31. 25KBd

Foundation Fieldbus H2 (fast Ethernet)

HART

The system allows different types of field buses to be mixed and run simultaneously in the same field controller PS.

Industrial “field control explosion (AC800F) consists of the following components:

Basic unit pm802f

Power supply sa801f/sd802f

Ethernet network card ei801f/ei802f/ei803f

Fieldbus interface card fi810f/fi820f/fi830f

Various accessories

The main components of the field controller PS are described below.

Basic unit pm802f

The basic unit pm802f is composed of a metal rack and a CPU motherboard. It periodically scans the data from the

The signals of the field bus sensors are processed according to the control application program configured by the user, and then the calculation results are passed

The fieldbus interface card returns the corresponding fieldbus actuator.

Two field controllers can realize controller 1:1 redundancy, and undisturbed switching between master and slave PS. Two on each PS

Ethernet network card, the second network card is used to connect the system network diginets), and the second network cards can be interconnected with each other to form a special

Redundant communication link (diginetr) to ensure information synchronization between master and slave PS. — However, the master PS fails, and the slave PS can quickly and undisturbed connect the replacement worker

Make. All inputs and outputs also support redundant operation.

The data communication between the field process controller PS. operating station 0s and the engineer station es is completed by the system network (diginets), which is inserted

The – Ethernet network card on the PS basic unit provides the interface between PS and diginets. ES. Hardware configuration and PS

The user program is downloaded to the PS CPU through diginets and the first network card. After the field bus interface card is newly installed or replaced, the required group

The status information will be automatically reloaded. The configuration results and real-time process data are stored in RAM, and ram is installed on the Ethernet network card or battery card

The backup battery can maintain the configuration content and data in case of power failure.
