Overview

Part 1105779-04
E 2014 Nordson Corporation
CAN and Ethernet Networks
Refer to the system diagrams in Section 7.
CAN Network: Handles communications between the gun control cards,
iFlow modules, and the iControl PC, and with other iControl consoles.
Ethernet Network: Handles communications between the iControl system
and remote devices such as optional in/out positioners, reciprocators, and
scanners.
Digital Inputs
The iControl master console includes an interface board that provides
optically isolated digital inputs. Included are
S eight inputs for zone detection
S eight inputs for part identification
S one input for a conveyor motion encoder
S one input for a conveyor interlock
S one input that locks out guns when any booth exhauster is off (only used
on multiple booth systems using a single iControl)
The encoder and the devices (photoeyes or scanners) or customer inputs
used for zone and part ID detection are connected to a terminal block in the
Photoeye Junction Box (PEJB). A 24Vdc power supply in the PEJB
provides power for these devices.
A 25-conductor input cable connects the PEJB to the iControl master
console. If the master console cannot be located within direct wiring range
(19 ft) of the PEJB, an extension box and extra cable is provided. If the
system is equipped with a remote I/O (Ethernet) network, then the
25-conductor cable is routed through a network junction box.
Encoder
The iControl system provides one optically isolated digital input for a
conveyor motion encoder. The encoder can be either mechanical or optical
and must have a 50% duty cycle.
Resolution: At an encoder resolution of one inch to one pulse (1:1), the
effective distance parts can be tracked by the iControl system is
approximately 1333 feet. At a 2:1 resolution (
1
/
2
inch per pulse), the
effective tracking distance is halved, to approximately 666 feet.
The maximum speed of the encoder input is 10 Hz (10 pulses per second).
This may require a trade off between desired conveyor speed and part
tracking resolution (the higher the conveyor speed the coarser the tracking
resolution).
NOTE: A timer may be used instead of an encoder. Consult with your
Nordson representative.
