- 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
INFI-NET is a unidirectional, high-speed serial data highway shared by all INFI 90 OPEN nodes. INFI-NET provides sophisti- cated interfaces for data exchange. This process control unit interface is made up of state-of-the-art INFI 90 OPEN modules.
Through the NPM and NIS interface the process control unit has access to INFI-NET. At the same time the NPM module communicates with the control modules via the Controlway. The process control unit interface can support hardware redundancy. In a redundant configuration, there are two NIS modules and two NPM modules. One pair of modules is the primary. If the primary modules fail, the backup modules come on-line. Redundant data highway communication capability is a standard feature.
The NIS module is an I/O module that works in conjunction with the NPM module. This allows a node to communicate with any other node on the INFI-NET loop. The NIS module is a single printed circuit board that occupies one slot in the module mounting unit. The circuit board contains microprocessor based communication circuitry that enables it to interface with the NPM module. Two latching screws on the faceplate secure the NIS module to the module mounting unit. There are 16 LEDs on the faceplate that display error codes and event/error counts. The NIS module has three card edge connectors for external signals and power (P1, P2 and P3). Connector P1 connects to the module power source. Connector P2 connects the NIS module to the I/O expander bus to communicate with the NPM module. Serial communication to other nodes is through con- nector P3 using a cable connected to a termination unit or termination module. Communication between nodes is through coaxial or twinaxial cables that connect the termination units or modules on each node.
The NPM module acts as a translator between INFI-NET and Controlway. The NPM module holds the process control unit database and directs the communication process between the modules residing on Controlway and the NIS module. The NPM module is a single printed circuit board that occupies the slot adjacent to the NIS module in the module mounting unit. The circuit board contains microprocessor based communication circuitry that enables it to interface with the NIS module and all Controlway modules. Two latching screws on the NPM module faceplate secure the module in the module mounting unit. The faceplate contains eight CPU LEDs, a status LED, and a stop/reset pushbutton. The NPM module has three card edge connectors for external signals and power (P1, P2 and P3). Connector P1 connects to common (ground), +5 VDC power, and the Controlway. Connector P2 connects the NPM module to the NIS module. Connector P3 provides for communication between primary and backup process control unit interfaces. The NPM module communicates with the NIS module within its process control unit through the I/O expander bus.

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.
Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.
InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.
It's like having the store come to you!

Excellent company, employees, and service! Tim, Ann, and Todd are stellar to work with during transactions.
Have dealt with Artisan for over a decade and have always found them to be knowledgeable, professional and have a great inventory to choose from! Great company!
We have some test equipment in our lab from the 1990's that stopped working about 2 years ago. It sat in the corner collecting dust, but we took on a project last month that required more machines. After talking to Artisan, we found out we could get parts to fix our machine for much less than buying a new one!
