Gocator Line Profile Sensors: User Manual
How Gocator Works • 78
One of the main functions of Gocator sensors is to produce pass/fail decisions, and then control
something based on that decision. Typically, this involves rejecting a part through an eject gate, but it can
also involve making decisions on good, but different, parts. This is described as “output” in Gocator.
Gocator supports the following output types:
l Ethernet (which provides industry-standard protocols such as Modbus, EtherNet/IP, and ASCII, in
addition to the Gocator protocol)
l Digital
l Analog
l Serial interfaces
An important concept is digital output tracking. Production lines can place an ejection or sorting
mechanism at different distances from where the sensor scans the target. For this reason, Gocator lets
you schedule a delayed decision over the digital interfaces. Because the conveyor system on a typical
production line will use an encoder or have a known, constant speed, targets can effectively be “tracked”
or "tagged."Gocator will know when a defective part has traveled far enough and trigger a PLC to
activate an ejection/sorting mechanism at the correct moment. For more information on digital output
tracking, see Digital Output on page 438.
