Get manufacturing flexibility without
compromising your systems reliability with eNETDNCs
Wireless DNC. eNETDNCs Wireless DNC can connect
all your CNCs or can be used in conjunction with an eNETDNC
cabled DNC network system. In today's lean manufacturing environment,
machine tools need to be more mobile. eNETDNCs Wireless
DNC solution enables CNC mobility without loss of DNC integrity.
The eNETDNC Wireless solution is based on the 802.11b
wireless Ethernet standard and can be configured to work with an
existing wireless network or as a stand-alone system. The wireless
configuration is flexible; it can be installed to include all of
the CNC machines or used in combination with a wired installation.
- No Need to string wires
- Move machines without moving cables
- No issues with shop interference or noise
- Remote access from machine control
- Encrypted for security
- Built in verification for insured data integrity
Each CNC machine is connected to the network via a
single port eNETDNC Wireless CNC Unit that converts the RS-232 to
Ethernet. This is linked to a eNET Wireless Access Point that communicates
to the network. The wireless option eliminates the cost of the running
cable to each machine and allows customers to move machines throughout
the shop with out changing the DNC system. For the machine shop
that would like to have both options, one system can be configured
to handle both communication methods.
A eNET Wireless Access Point mounted in the ceiling
or high point above the shop acts as communications hub for transmitting
NC programs to individual machines on the floor. This strategically
placed device, acts as an Ethernet client bridge, and transmits
part programs to all CNCs having eNETDNC Wireless CNC Units. Transmission
is good for up to 200 feet of line of sight.
shop cannot be lean without DNC"
Operators access the eNETDNC system as if it were
hardwired to the CNC, with no difference in how the DNC interface
functions. The eNETDNC Wireless CNC Unit on each machine converts
incoming NC programs from Ethernet data into RS-232 signals for
input to the CNC's serial communications port.
Drip-feeding long NC programs are not a challenge
with the eNETDNC Systems. It is able to drip/spoon feed multiple
CNC machines simultaneously.
A key aspect of the eNETDNC software, which resides
on the DNC server, is communicating with each individual machine. The
single port eNETDNC Wireless CNC Units are designed to specifically
work with the eNETDNC configuration which simplifies the entire
system and therefore is a more reliable connection.
This software allows the shop to assign a specific
IP address on the DNC server for each of the CNC machine ports.
This capability eliminates the need for a separate serial port server.
key issues with wireless DNC are security and interference. The
single port eNETDNC Wireless CNC Units was designed to convert the
serial signal prior to transmitting thus allowing the wireless device
to encrypt data at the point of transmission. The Ethernet
to RS-232 converters decode the data before the file is passed to
the CNC. The eNETDNC system uses a radio frequency within a
bandwidth recently dedicated to wireless networks, which makes it
immune to interference from other sources.
The eNETDNC Wireless DNC System has security restrictions
limiting the permissible IP addresses it will accept. No new machines
can be added to the eNETDNC system unless a IP address is added
to the DNC server. The system administrator can log onto the
eNETDNC's operating system and change its directory of addresses.
The eNETDNC system can be expanded to support an unlimited number
of machines. Moreover, the machines can be moved at any time, and
more machines can be added to the network without incurring new
Even older NC machine tools can be used within an
eNETDNC Wireless DNC System. eNETDNC designs and builds BTR
Interface Boards and factory hardened eNET e-Terminals thereby allowing
older NC machine to be used with the eNETDNC Wireless CNC Units.
