Hello everyone! I have read through the following Thread: [How to set a the IP-Address of GEV-Camera programmatically in CVB - Programming Questions / C++ API - Common Vision Blox User Forum](https://forum.commonvisionblox.com/t/how-to-set-a-the-ip-address-of-gev-camera-programmatically-in-cvb/274) What Andreas coded it’s an example of what I’d like to re-create in Python, basically setting a static IP Address on a Camera that is or is not in my subnet. Changing one by one with the GenICam software it is easy, but I would like to automate the process thanks to a Network Switch and Python, in order to get the job done quicker and spend energies and resources on something else in the meantime. I have tried to code something similar, but without success. I have not found much on the documentation unfortunately (or maybe it’s just me being blind). Does anybody know how to solve this one? Many thanks, Axel ---

@axelprinceton Hey! I haven’t actually done that, but from looking at the C++ code (or C# [https://forum.commonvisionblox.com/t/exception-during-discovery/318/8](https://forum.commonvisionblox.com/t/exception-during-discovery/318/8) ), this should be possible. All the functions should also be available in Python. Do you have any idea why your version fails? Maybe we can solve it together 🙂 Best Regards, Silas ---

Hello @silas, thanks for your answer. Forgot to mention that I am working with cvbpy 1.5, on python 3.10.9 (conda) and CVB 14.00.002 on Windows. I believe part of my code may be incorrect, also I do believe it is incorrect to open the device with the access token, but as the first link and your link suggest, the interface needs to be accessed instead. ```auto import os import time import ipaddress import socket import cvb cameras = {} print("Looking for Cameras...") iflags = cvb.DiscoverFlags.UpToLevelInterface | cvb.DiscoverFlags.IgnoreGevSD all_interfaces = cvb.DeviceFactory.discover_from_root(iflags) bflags = (cvb.DiscoverFlags.IgnoreVins | cvb.DiscoverFlags.IncludeInaccessible | cvb.DiscoverFlags.IgnoreGevSD) for interface in all_interfaces: cvb.DiscoveryInformation.set_genapi_feature(interface, "TLInterface", "DisableSubnetMatch", "1") cvb.DiscoveryInformation.set_genapi_feature(interface, "TLInterface", "AllowBroadcastDiscoveryResponse", "1") found_devices = cvb.DeviceFactory.discover_from_level(interface.access_token, bflags) if len(found_devices) > 0: print(f"{len(found_devices)} devices discovered.") for i in range(len(found_devices)): access = found_devices[i].access_token devsn = found_devices[i].read_property(cvb.DiscoveryProperties.DeviceSerialNumber) devip = found_devices[i].read_property(cvb.DiscoveryProperties.DeviceIP) devmac = found_devices[i].read_property(cvb.DiscoveryProperties.DeviceMac) accstat = found_devices[i].read_property(cvb.DiscoveryProperties.DeviceAccessStatus) if devip not in [camera_info["IP"] for camera_info in cameras.values()]: camera_name = f"cam{len(cameras)}" cameras[camera_name] = {"SN": devsn, "IP": devip, "MAC": devmac, "Access Status":accstat} for i, camera in enumerate(cameras, start=1): print(f"{i}. Camera {camera}: {cameras[camera]}") print("") choice = input("Choose a camera (1-{}), or press 'Enter' to rescan: ".format(len(cameras))) if choice.isdigit() and 1 <= int(choice) <= len(cameras): camera_name = "cam{}".format(int(choice)-1) print("You selected {}.".format(cameras[camera_name]["SN"])) print("") time.sleep(1) os.system("cls") #rest of my code.... #snippet elif mchoice == "15": ipconst = "10.2" room_n = int(input("Enter the Room number: ")) if room_n < 10: room = f".10{room_n}" elif room_n >= 40: print("Number is too great") else: room = f".1{room_n}" camera_number = int(input("Enter the camera number (0-5): ")) if camera_number == 0: cam = ".11" elif camera_number == 1: cam = ".12" elif camera_number == 2: cam = ".13" elif camera_number == 3: cam = ".14" elif camera_number == 4: cam = ".15" elif camera_number == 5: cam = ".16" else: print("Invalid camera number") time.sleep(1) ip = ipconst + room + cam subnet = "255.255.255.0" ip_address = ipaddress.ip_address(ip) sub_address = ipaddress.ip_address(subnet) hex_ip = socket.inet_aton(str(ip_address)).hex() hex_sub = socket.inet_aton(str(sub_address)).hex() print(ip) print(hex_ip) print(hex_sub) with cvb.DeviceFactory.open(access) as device: deviceUpdateListNode = cvb.CommandNode("DeviceUpdateList") cfgIPNode = cvb.IntegerNode("IPCfg_IP") cfgSubnetNode = cvb.IntegerNode("IPCfg_Subnet") cfgForceNode = cvb.CommandNode("IPCfg_SetForceIP") cfgStaticNode = cvb.CommandNode("IPCfg_SetStatIP") deviceUpdateListNode.execute() cfgIPNode.value(hex_ip) cfgSubnetNode.value(hex_sub) cfgForceNode.execute() deviceUpdateListNode.execute() cfgStaticNode.execute() print("IP address Flashed: " + ip) time.sleep(2) os.system("cls") time.sleep(1) ``` Thanks again for your help!

@axelprinceton Hey there! I think the issue is caused by the following lines of your code: ```cs with cvb.DeviceFactory.open(access) as device: deviceUpdateListNode = cvb.CommandNode("DeviceUpdateList") cfgIPNode = cvb.IntegerNode("IPCfg_IP") cfgSubnetNode = cvb.IntegerNode("IPCfg_Subnet") cfgForceNode = cvb.CommandNode("IPCfg_SetForceIP") cfgStaticNode = cvb.CommandNode("IPCfg_SetStatIP") ``` Here, you create new Command/Integer Nodes, but they aren’t referenced to any device. If you have a look at the C# example I sent you, there is a method called ‘ForceIP’ that does the same thing, but it gets the nodes from the passed-in ‘iface’ NodeMap. This way it should be referenced 🙂 ```cs var ifaceToOpen = allInterfaces .First(iface => iface[DiscoveryProperties.InterfaceId] == cam[DiscoveryProperties.InterfaceId]); using (var ifaceDevice = DeviceFactory.Open(ifaceToOpen)) { ForceIP(ifaceDevice.NodeMaps[NodeMapNames.Interface], cam, newIP); } static void ForceIP(NodeMap iface, DiscoveryInformation camera, IPAddress newIP) { var macAddress = PhysicalAddress.Parse(camera[DiscoveryProperties.DeviceMac]); var subnet = GetInterfaceSubnetMask(camera); var updateDeviceList = iface["DeviceUpdateList"] as CommandNode; updateDeviceList.Execute(); var cfgMac = iface["IPCfg_MAC"] as IntegerNode; cfgMac.Value = MacToInt(macAddress); var cfgIP = iface["IPCfg_IP"] as IntegerNode; cfgIP.Value = IPToInt(newIP); var cfgSubnet = iface["IPCfg_Subnet"] as IntegerNode; cfgSubnet.Value = IPToInt(subnet); var cfgForceIP = iface["IPCfg_SetForceIP"] as CommandNode; cfgForceIP.Execute(); } ``` In Python, you’ll access the needed Nodemap with the following code: ```py import os import cvb import ipaddress # Load driver device = cvb.DeviceFactory.open(os.path.join(cvb.install_path(), "drivers", "GenICam.vin"), port=0) #Load Interface NodeMap for the device dev_node_map = device.node_maps["TLInterface"] IPcfg = dev_node_map["IPCfg_IP"] print("IPcfg: " + str(ipaddress.IPv4Address(IPcfg.value))) IPcfg.value = int(ipaddress.IPv4Address("192.168.1.48")) print("IPcfg: " + str(ipaddress.IPv4Address(IPcfg.value))) ``` Here are all the nodes that the ‘Interface’ Nodemap holds. You can look at them yourself in the GenICam Browser 🙂 ![Interface Port](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/2X/4/4445b1eea1865019edb6acd83ed8c3c3916095cd.png) I hope that helped you. If you need further assistance, feel free to come back to me 🙂 Regards Silas ---

Hello Silas. Sorry for the long wait, been on and off multiple projects! I have tried your resolution and followed your advice. I have also adapted your example to my code to match it and make it work the way intended. Unfortunately, none of the node maps really changed, the IP/Subnet/gateway stay 0.0.0.0 on: IPCfg\_IP / IPCfg\_Subnet and IPCfg\_Gateway even by doing it manually via GenICam browser. By using the access token “access = found\_devices[i].access\_token” the code you provided me runs just fine, but yet no change on IP address of the actual camera. While by using this one: ```auto device = cvb.DeviceFactory.open(os.path.join(cvb.install_path(), "drivers", "GenICam.vin"), port=0) ``` unfortunately it throws me an error: ```auto access = cvb.DeviceFactory.open(os.path.join(cvb.install_path(), "drivers", "GenICam.vin"), port=0) RuntimeError: C-API call failed; try getting a log by using CVB LogGUI/silogutil: {"Name": "LoadImageFileW", "CVC_ERROR_CODE": 1} ``` While on LogGUI I don’t see any logs. Now I am wondering if there is a way to change the IP address without accessing the camera nodemaps, the same way I do manually by right-clicking the camera in GenICam Browser and selecting Assign IP, as the nodemaps related to them are all read-only if the camera is accessed via token. ![image](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/2X/d/df59a859f77035e6b7c1799c299d3b6a807e70cb.png) ![image](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/2X/6/6e5350da20fe5a78b48b5227db38b8bb59c81201.png) Basically, instead of editing the nodemaps, I will edit what’s in the NIC. Many thanks, Axel Princeton ---

@axelprinceton Hey! Sorry for the delayed response. I was out of the office 🙂 I think you identified the problem in the last line. As of my knowledge, if your NIC is set to DHCP, you can’t set a persistent static IP that is outside of your network range. If you set the desired range in your NIC, the code should work. Thanks and regards Silas
