Introduction
Project Introduction

One of the world's leading machine builders plans, develops, manufactures, and installs machines and complete filling, labeling, and packaging lines. As an innovator in Ethernet controlled machine automation, the company is expanding its integrated machine solutions, leading a paradigm shift in machine control that is essentially the equivalent of putting an industrial network onto a single machine or set of machines. Ethernet offers this builder numerous advantages for their lineup of solutions, which includes stretch blow-molding technology, filling and closing technology, cold-aseptic filling, labeling and dressing technology, inspection and monitoring technology, washers, rinsers and pasteurizers, packing and palletizing technology, conveyor technology, systems engineering, process engineering, and brewing technology. One of their primary solutions is a soft drink bottling production line that comprises three primary machines—a filling machine, a labeling machine, and a packaging machine. The company was looking for several best-in-class, industrial strength Ethernet switches to form an "internal network" for this and other product lines.



Moxa Solution

Each of these machines is made up of a combination of PLC controllers, HMI control panel, and numerous I/Os, relays, sensors, and counters. The machine builder needed a proven and reliable Ethernet switch to form the internal network that allows these Ethernet-based devices to communicate at the system (machine) level, as well as port out to the factory floor to integrate with other process machinery and allow remote monitoring and control. Since the company designs and builds machinery for the food packaging industry, sanitation and maintenance requirements play a critical role in system design. Machinery must withstand high-pressure and high-temperature washdowns as well as the cleaning solvents used for sterilization. Rugged, centralized machine control that uses watertight sensors and enclosed Moxa Ethernet switches to support the machinery have made it possible to design systems that can better withstand and support these demanding operating requirements.

The builder used the Moxa EDS-305-M-SC, EDS-308-M-SC, and EDS-316-M-SC unmanaged Ethernet switches. These rugged Ethernet switches are designed to withstand the wide temperature shifts, vibrations, and EMC prevalent in industrial environments. All of these switches support one multimode fiber and are capable of transmitting data up to 5 kilometers, making it easier to configure and support reliable, high-speed data transfer between machines or to the central control room used by large-scale operations. Important features of the Moxa switches include redundant DC power inputs, and models for standard temperature conditions (0 to +60°C) or wide range temperature conditions (-40 to +75°C). All of the switches come with a solid 5-year warranty and provide alarm relay contact outputs to warn operators and system controllers when the power fails or a port link breaks.


 


Why Moxa

  • These rugged Ethernet switches are designed to withstand wide temperature, vibrations, and EMC, and come in an IP30 rated casing for application in harsh environment.
  • The selected switches support multimode fiber and are capable of transmitting up to 5 kilometers to fulfill the long-haul transmission requirements of largescale factories.
  • The T models of Moxa Ethernet switches are rated to operate reliably under extreme temperature conditions from -40 to 75°C.
  • The fanless, low-power design ensures a high MTBF, for long-term, trouble-free operation, which ease the maintenance effort for both machine builder and end user.
  • The switches can send out a warning message by relay output when power failures or port break are detected, providing field engineers with real-time alarm.
