Introduction
Project Introduction

A pulp mill originally used a PLC with I/O wiring stretching 100 feet or more over the factory floor to collect sensor data. After the system had been used for several years, it was determined that the cost of replacing the I/O and communication cables and overhauling the entire cabling system was cost-prohibitive. For this reason, the pulp mill decided to use Moxa’s smart I/O products, which offer a cost-effective cable replacement solution that utilizes the factory’s existing Ethernet infrastructure together with a WiFi network to transmit sensor signals as TCP/IP packets back to the PLCs.

 



Moxa Solution

The pulp mill decided to leverage their existing Ethernet infrastructure and cut costs by using Moxa’s ioLogik E1200 active Ethernet I/O products, which support peer-to-peer input-to-output signal regeneration. The ioLogik E1200 smart remote I/O devices support channel-to-channel mapping over Ethernet by using an emitter and receiver I/O pair to simultaneously transmit to multiple targets, and allow the destination’s socket ports to be specified separately for each channel map. This technology provides the flexibility needed to install ioLogik units behind a router or firewall.
In addition, the smart remote I/O devices can replicate both digital and analog input signals to remote output modules over any TCP/IP communication medium, without using an external controller or server. One of the strengths of using TCP/IP is that you can use an existing Ethernet infrastructure to build your sensor network, without needing to install additional cabling.


Why Moxa

• Does not require programming or using a controller
• Uses an existing Ethernet infrastructure to reduce cabling and wiring costs
• Dual Ethernet ports for easy I/O cascading and expansion
