The SNAP PAC rack-mounted Wired+Wireless Programmable Automation
Controller (SNAP-PAC-R1-W) is the most powerful and versatile I/O and
controller combination available. This controller works like a laptop - plug an
Ethernet cable in for traditional networking, or switch on the Wi-Fi radio for
wireless networking. No additional I/O hardware is required to use wireless and
all functions work the same no matter which networking method is used. Also,
all standard industrial protocols currently supported by the SNAP-PAC-R1-W's
Ethernet interface are fully supported over wireless as well, including
OptoMMP, ModbusÂ®/TCP, EtherNet/IPTM, FTP, SNMP, SMTP, and more. The dual (wired
plus wireless) functionality of this controller gives automation professionals
more industrial networking options, thereby making it easier for them to
design, build, and modify their control systems. It allows them to use
controllers and I/O in remote or inaccessible areas, or where network wiring is
difficult or impossible to install. They can realize significant cost savings
by eliminating typical network wiring and termination. At the same time, users
can easily switch from wireless to a wired network if necessary, or use both simultaneously,
thereby effectively segmenting the two networks. The SNAP-PAC-R1-W is the first
system of its type to provide each of the major 802.11 variants (a, b, g) in
one offering. Part of the product's uniqueness is that the wireless
capabilities are built into Opto 22's standard product line. This approach
contrasts with competing solutions from other vendors that typically offer
separate and distinct wired and wireless product lines. This approach increases
risk and adds costs in software, training, and stocking of spares. With the
SNAP-PAC-R1-W, however, end-users, system integrators, design engineers,
machine builders, OEMs, and others make one investment and gain the ability to
design using Ethernet wiring, wireless, or both.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
