The VersaMax™ Nano Controller from GE Fanuc Automation, http://gefanuc.com/products/controllers,
targets high-volume applications with cost, space, and fast-processing-speed
constraints. "Its $180 list price makes it a more flexible option for engineers
designing counter-, timer-, and relay-based control systems," says Product
Manager Bill Black. With only 10 I/O points, Nano targets applications that need
powerful control, but not high I/O counts. The compact (75- x 80- x 47-mm) PLC
includes 2K words of memory, PID, floating-point math, subroutines, and serial
read/write commands. It supports up to two high-speed counters (10 kHz) and has
three PWM/pulse train outputs (5 kHz). Standard RS-232 communication can be used
for SNP Slave, Modbus RTU Slave, or Serial In/Out commands. Plus, the new
VersaMax SE Module connects Micro and Nano controllers to Ethernet so users can
solicit and send information, upload/download programs, and monitor and control
devices over Ethernet.
Sales of semiconductors, interconnects, and other electronic components in North America were flat through the second quarter of 2015, reflecting a pattern that’s been repeating itself for several years.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
