What is a Field Network?

A field network is a dedicated network that connects controllers, sensors, monitors, and other equipment used on the factory floor to support control and data collection. Its implementation offers the following benefits.

Simplification of wiring
Rapid troubleshooting
Promotion of overall system visualization
Streamlining maintenance, inspection, and operational management, etc.

This technology has been gaining even more attention in recent years because it is directly linked to improving productivity at the field level.

Are you having trouble with inconsistent standards?

By introducing a field network...

〉〉 You can consolidate wiring connections

Reduced installation costs through simplified wiring
Wiring work is reduced, allowing for lower installation costs.
Improved maintainability
Wiring becomes simpler, making maintenance easier.

>> Furthermore, adding equipment is also easy

Improved reliability
Since wire breaks can be detected, wiring faults are identified quickly, leading to improved system reliability.
Improved flexibility
Wiring changes become easier, increasing system flexibility.

Role and Effects of Field Networks

What you can do with Field Networks × Robots

Robot operation and stop instructions can be issued.
Operating status, position, and alarms can be communicated to the host PLC/PC.
Operation programs and parameters can be set remotely.

Benefits of integrating robots into a field network

Multiple robots can be easily controlled in synchronization.
Reduction of downtime through faster response to abnormalities.
Product types and programs can be flexibly changed according to production status.

Types of Field Networks and How to Choose Them

There are multiple protocols for field networks, such as EtherNet/IP, PROFINET, and CC-Link IE, which differ in interoperability, communication speed, and ease of implementation.
The CC-Link IE field network is characterized by its high-speed communication and scalability, making it easy to retrofit equipment onto active lines. On the other hand, EtherNet/IP is highly versatile, supports products from many overseas vendors, and offers excellent compatibility.
It is important to select the optimal network while considering the requirements of your facility and future expansion plans, with an eye toward long-term cost performance.

Supported standards

Field Network Glossary

Open Field Network:

A standardized field network that does not depend on a specific manufacturer. This allows devices and systems from different manufacturers to be compatible and work together flexibly.

Real-Time Communication:

Real-time communication capability refers to the network's ability to reliably transmit data within a certain latency. Real-time communication is extremely important in industrial automation and process control.

Scalability:

Scalability refers to the characteristic that a system or network can be expanded. Excellent scalability means that it is easy to add new devices or nodes, allowing for flexible responses to future system expansions or changes.

Node:

A node refers to an individual device or piece of equipment connected to a network. In a field network, sensors, actuators, controllers, etc., function as nodes. Each node has its own unique address and communicates over the network.

FAQ

Q Is it possible to use the SHOTMASTER I already own?

A Yes, it is possible.
If it is a series currently on sale (click here), you can install an additional field network unit.

Q Are there any limitations when using a field network unit?

A The robot's RS-232C communication will no longer be available.

Q Is it possible to issue program instructions from a host system?

A Yes. It can be operated with a feel similar to I/O signals.
In addition to channel instructions, you can perform operations such as execution, stop, and return to origin.

Q Is it also possible to edit programs?

A Yes, it is.
By using the FNW communication mode, you can read and write step data.
