How to set values for IPD and PacketSize by code?

[lcflorindo]

Hi, everytime that I turn my whole system off, I must set the Packet Size and Inter-Packet Delay values throught pylon software before use the camera again (else I get the buffer error).

There is a way to do it by code? (Then everytime I run my programm it sets automatically)

Thanks in advance.

You can always lookup the parameters in the normal camera documentation

docs.baslerweb.com

The translation between C++ and python is nothing more than search-and-replace:

Take care to call camera.Open() before accessing camera features.

C++

// Payload Size
int64_t payloadSize = camera.PayloadSize.GetValue();
// Packet Size
camera.GevSCPSPacketSize.SetValue(1500);
// Inter-Packet Delay
camera.GevSCPD.SetValue(1000);
// Frame transmission delay
camera.GevSCFTD.SetValue(1000);
// Bandwidth Assigned
int64_t bandwidthAssigned = camera.GevSCBWA.GetValue();
// Bandwidth Reserve
camera.GevSCBWR.SetValue(10);
// Bandwidth Reserve Accumulation
camera.GevSCBWRA.SetValue(10);
// Frame Jitter Max
int64_t jitterMax = camera.GevSCFJM.GetValue();
// Device Max Throughput
int64_t maxThroughput = camera.GevSCDMT.GetValue();
// Device Current Throughput
int64_t currentThroughput = camera.GevSCDCT.GetValue();
// Heartbeat Timeout
camera.GevHeartbeatTimeout.SetValue(5000);

becomes:

Python

# Payload Size
int64_t payloadSize = camera.PayloadSize.GetValue()
# Packet Size
camera.GevSCPSPacketSize.SetValue(1500)
# Inter-Packet Delay
camera.GevSCPD.SetValue(1000)
# Frame transmission delay
camera.GevSCFTD.SetValue(1000)
# Bandwidth Assigned
int64_t bandwidthAssigned = camera.GevSCBWA.GetValue()
# Bandwidth Reserve
camera.GevSCBWR.SetValue(10)
# Bandwidth Reserve Accumulation
camera.GevSCBWRA.SetValue(10)
# Frame Jitter Max
int64_t jitterMax = camera.GevSCFJM.GetValue()
# Device Max Throughput
int64_t maxThroughput = camera.GevSCDMT.GetValue()
# Device Current Throughput
int64_t currentThroughput = camera.GevSCDCT.GetValue()
# Heartbeat Timeout
camera.GevHeartbeatTimeout.SetValue(5000)

Issue has been solved by adding these two lines into code:

Packet Size

camera.GevSCPSPacketSize.SetValue(1500) # using 9000 causes grabbing image is not successful every single time

Inter-Packet Delay

camera.GevSCPD.SetValue(2000)

Thanks for the support! It worked!

I am using a acA1300-200uc, and when I try to set its attributes, I get the following error:
Exception Node not existing (file 'genicam_wrap.cpp', line 16130) Exception initializing camera

This only happens when I try to set PacketSize and IPD. Acquisiting rate and exposure time methods don't seem to have the same problem

@kesaroid .... You own a USB camera ... GIGE specific parameters are not available on your device.

Please check the docs.baslerweb.com for your camera specific parameters
