Conveyor controls architecture based upon modular distributed devices connected via
ConveyLinx
Ethernet network.
Conveyor control module that is part of the ConveyLinx family. Each module can
ConveyLinx-Ai /
accommodate up to 2 MDR conveyor zones. The modules allow connection for Senergy-
ConveyLinx-Ai2
Ai platform motor rollers and gear drives.
Dynamic Host Configuration Protocol A protocol for assigning IP addresses to devices on
DHCP
a network from a pool of available IP's. A dynamic IP address changes each time the
device connects to the network
This is the type of a particular connector , which has four connector pins and is used on
M8
the ConveyLinx Ai2 modules for both sensor connectors and MDR connectors
Light Emitting Diode – In the context of this document, LED's are used on the
LED
ConveyLinx-Ai2 to provide visual indication of module status
Term used to describe how the signaling output circuit of a photo-sensor is configured
when it detects its reflected light. A photo-sensor that is light energized will activate its
Light / Dark Energized
output circuit when it detects its reflected light. A dark energized photo-sensor will
activate its output circuit when it does not detect its reflected light.
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
Normally Open /
sensor would have its output circuit energized when it detected its reflected light and its
Normally Closed
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.
Electronics term that indicates the type of transistor circuit used for a logical input or
NPN / PNP
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.
A device, mounted near the end of the conveyor zone to sense the presence of a load on
Photo-sensor
the zone
Programmable Logic Controller – A wide variety of industrial computing devices that
PLC
control automatic equipment
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.
Retro-reflective /
Reflex (or sometimes known as proximity) type photo-sensors emit light to be reflected
Reflex
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.
The IP Code (International Protection Marking) specifies the device's degree of
IP54
resistance to intrusions, dust and water. IP54 certified device must be fully protected
from splashed water , dust particles and completely protected from contact
