Series of 1-8 port MEI (RS-232/422/485) device servers.
Automated factories often have computer numerically controlled
(CNC) machines in the production line. CNC machine tools move in precise
increments according to instructions processed by dedicated CNC computers.
Direct Numerical Control (DNC) software is used for automatic instruction
code generation and entry. Traditionally, uploads to the CNC computer
meant long, cumbersome serial cables or floppy disk transfers. Now Ethernet
netowrks and device servers offer easy data transfers from the network
jack of an engineer's PC to the COM port on a CNC computer--just as if
the CNC were directly attached to the COM port on the engineer's own PC.
Quatech device servers are the #1 Performer for CNC/DNC
Networking Applications because they offer the industry's lowest latency
and highest throughput. This low latency advantage is particularly
important because it eliminates buffer overflow errors when drip-feeding.
Further, remotely accessing machine tools using a single connection to
simultaneously uptate multiple CNC machines, instead of manually updating
each one on the factory floor, increases both safety and convenience.
It also completely eliminates the need for A/B switch boxes, long serial
cable runs, and floppy disks.
Ideal for use in most industrial enviornments, Quatech
device servers are housed in a sturdy metal case and can be easily DIN-rail
or rack mounted. The diagram below depicts a typical CNC?DNC programming
system.
