NOTE: The M-Series Cameras support Delay Debounce on the Trigger input (Frame Trigger on Line Scan
camera).
The M-Series Cameras do not support Holdoff Debounce on the Trigger or Frame Trigger, only Delay
Debounce.
The M-Series Line Scan Camera does not support any Debounce setting on the Line Trigger.
The M-Series Processor does not support any Debounce setting on Event Inputs.
Third-party cameras have varying Delay and Holdoff Input Debounce settings. Refer to the M-Series Cam-
era and Processor Guide (843-0138) for details.
• Delay: The debounce timer starts when the hardware signal’s active edge is detected, and stops when
the opposite edge is detected. The input must remain active for the delay amount of time for the cam-
era or event to be triggered.
Delay is good for filtering random noise on the input, but delay makes the time between the input sig-
nal’s edge and system triggering speed-dependent, especially on high-speed inspections. Use a Delay
time that is long enough to filter out the worst expected noise, but short enough to accommodate your
fastest inspection times.
• Holdoff: The shift, or event is triggered when the hardware signal’s active edge is detected, but
another active edge will not trigger the input until the Holdoff time has elapsed.
Holdoff is good for noise on the signal’s leading edge and it is not speed-dependent, but it is suscepti-
ble to random noise on the input signal. Use a Holdoff time long enough to reject leading edge noise,
but not so long that the inspection rate is limited.
Enable OPC/ActiveX Server
If this check box is checked, the OPC/ActiveX Server on the device will be started each time the device
starts. This server must be running if you are using OPC Data Access (see “OPC Data Access” on page 2-
42) or the Impact ActiveX Interface (refer to the Impact ActiveX Reference Guide 843-0119).
TCP/IP
This is the device’s Ethernet input port number where the device "listens" for a TCP/IP message. When a
message is received on this port, the device triggers the TCP/IP event and tasks that have the Task Trigger
event set to TCP/IP are queued to run.
You can use VPM’s TCP/IP Out tool in a task in another device to send messages to this port. The port num-
ber used in that TCP/IP Out tool should be the same as this port number. However, as the communication is
