Description
INFI-NET is a unidirectional, high-speed serial data highway shared by all INFI 90 OPEN nodes. INFI-NET provides sophisticated interfaces for data exchange. This process control unit interface is made up of state-of-the-art INFI 90 OPEN modules.
INFI-NET is a unidirectional, high-speed serial data highway that can be used by all INFI 90 OPEN modules. The INNIS01 Network Interface Slave Module (NIS) and the INNPM11 Network Processing Module (NPM) make up the process control unit interface.
All INFI-NET communication modules have normal INFI 90 OPEN security functions that insure module integrity. The module hardware checks for illegal addresses and monitors the machine fault timer (MFT) and the I/O expander bus clock. If a module detects an illegal address, it generates a bus error and displays an error code on the faceplate LEDs. If the microprocessor fails to reset the MFT timer, it expires. When this happens, the communication module stops and the status LED turns red. Module hardware also monitors the I/O expander bus clock. If there is no clock signal, the module hardware generates an interrupt.
Features
The process control unit interface has the following features:
• INFI-NET provides a plant wide communication network.
• INFI-NET provides time synchronization across the control system plant wide.
• Each node, depending on configuration, can operate independently of other INFI-NET nodes.
• The process control unit interface modules provide localized start-up/shutdown on power failure without operator intervention.
• The ten-megabaud communication rate gives timely information exchange.
• The NPM module packages process information for maximum transmission efficiency.
• The process control unit interface modules handle four message types: broadcast, time synchronization, multicast and NIS poll.
• All messages contain cyclic redundancy check codes (CRC) and checksums to insure data integrity.
