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.
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
