CAN and Ethernet Networks
Refer to the system diagram in Section 7.
CAN Network:
Handles internal communications between the gun control
cards, iFlow modules, and the iControl PC, and with other iControl consoles.
Ethernet Network:
Handles external communications between the iControl
system and remote devices such as optional in/out positioners,
reciprocators, and analog scanner controllers.
Digital Inputs
The iControl console includes an I/O 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 that locks out guns when any booth exhauster is off (only used
on multiple booth systems using a single iControl)
The encoder, zone and part ID photoeyes or discrete (digital) scanners with
or customer part ID inputs 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 console. If
the console cannot be located within direct wiring range (19 ft) of the PEJB,
an extension box and extra cable are provided. If the system is equipped
with a 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.
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.
