Normally Open /
Normally Closed
Control logic terminology to define the state of the output of a Boolean “on” or “off”
device. The term specifically describes the state of the output circuit when the device’s
sensing circuit is un-energized. In the context of photo-sensors; a normally open wired
sensor would have its output circuit energized when it detected its reflected light and its
output circuit would be de-energized when it did not detect its reflected light. Conversely
a photo-sensor wired normally closed would energize its output circuit when it did not
see its reflected light and it would de-energize its output circuit when it did detect its
reflected light
NPN / PNP
Electronics term that indicates the type of transistor circuit used for a logical input or
output for controllers. NPN devices will provide a common or ground connection when
activated and a PNP device will provide a logic voltage connection when activated
Photo-sensor
A device, mounted near the end of the conveyor zone to sense the presence of a carton
on the zone
PLC
Programmable Logic Controller – A wide variety of industrial computing devices that
control automatic equipment
PWM
Pulse Width Modulation – a control scheme that utilizes high speed switching transistors
to efficiently deliver power in a controlled fashion from the ConveyLinx controller to MDR
Retro-reflective /
Reflex
Term used to describe the two basic types of photo-sensors. Retro-reflective photo-
sensors utilize a reflective target that must be aligned with the photo-sensor such that
the light emitted by the photo-sensor is reflected back to it. ‘Reflex (or sometimes known
as proximity) type photo-sensors emit light to be reflected back from an object located
sufficiently close to the sensor. ‘For both types of photo-sensors, when they detect their
reflected light source, their signaling output circuit changes state.
RJ-11 / RJ-12
Registered Jack Style 11 / 12 – Standard connector / receptacle format utilizing 4 or 6
pin connections. The typical standard connection for telephones. RJ-11 utilizes 4 pins
and RJ-12 utilizes 6 pins but both styles use the same physical size.
RJ-45
Registered Jack Style 45 – Standard connector / receptacle format utilizing 8 pin
connections. The typical standard for computer network cable connections
Senergy-Ai
PulseRoller brand proprietary motor control platform that provides electronic intelligence
inside the motor that can be read by ConveyLinx-Ai and ConveyLinx-Ai2 control
modules. The connection from the motor to the controller is via 4-Pin M8 style connector
Singulation
Release
Conveyor control method for zoned controlled conveyor that dictates that when a zone
is discharging its carton, the upstream carton waiting to enter must wait until the
discharged carton is completely clear before it is allowed to enter
Slave Rollers
A set of non-motorized conveyor rollers mechanically linked to an MDR. The MDR and
slave rollers make up a physical zone. All of the slave rollers in a zone rotate at the
same speed and direction as the MDR because of their mechanical linkage
TCP/IP
Transport Control Protocol / Internet Protocol – IP is the protocol which oversees the
transmission of information packets from device to device on an Ethernet network. TCP
makes sure the packets have arrived and that the message is complete. These two
protocols are the basic language of the Internet and are often referred to together as
TCP/IP.
Train Release
Conveyor control method for zone configured conveyor that dictates that when a zone is
discharging, the upstream zone’s carton can move in unison with the discharging carton.
